IMac to tv with hdmi short circuit

I have my iMac (Intel) connected to my Sony tv with an hdmi adapter. It works fine except that sometimes the iMac seems to short circuit and turn off. I read once that my cable may not be appropriate but then I lost that info. Can anyone help?

For the "Arangements" option to appear, the external display must be turned on with the correct input selected and connected to the computer. Then close system prefs, reopen, go to "Display" and "Arrangement" will be along the top.

I want to connect my IMAC to TV with HDMI cable. I did it before going to Dispaly and Arrangments and then mirror. Now when I go to display I dont have to option of arrangements. Olny {Display and Color} pops up. Any ideas what happend to arrengements?

How do I use my late 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output.

May be this question has been asked thousand times. how do I use my mid 2011 iMac ( with thunderbolt) as external monitor for laptop/Xbox or other device with hdmi as output. if apple hasn't removed that feature and has just moved that functinoality to thunderbolt then how can I use it. currently there is no laptop available with thunderbolt output. no 3rd party converter available. whats the use of having feature on latest functionality if we cant use it. I wish they would have made one port has mini-dvi and other thunderbolt for backward compatibility untill some vendor comes up with converter.

It Says :
Mac (21.5-inch, Mid 2011) and iMac (27-inch, Mid 2011) and later computers support Target Display Mode via Thunderbolt to Thunderbolt cable (2 m) when the source is another Thunderbolt-equipped computer.
Name one computer model/vendor which has thunderbolt as output for display + audio. this is so stupid to move to new technology without availbility of its compatible devices.

IMac G3 Short Circuit Repair

Hello. I have an iMac G3 400 Ruby (summer 2000 I think). I tried to install LED beat lamps to the speakers, which worked for some time, however, a bad connection (I found this) in the wires leading to one of the LED's caused a short-circuit of the speaker when I turned on the machine. Smoke came out of the iMac before I could unplug it.
Now the iMac doesn't turn on. The green power LED comes on, but that's it. The screen stays dark, but sometimes lights up just a little. There are no sounds, and I can't hear the hard drive as usual.
I think the damage might be in the logic board or the analogue board. Where exactly do the speakers connect to on these computers? If it's the logic board, that will be easy to replace; I am very wary about opening up the CRT compartment to change out the analogue board.
Where do the speakers connect to and could that be where the damage is?
Thanks
-Nathan

Try following this procedure to reset the PMU to see if there is any improvement.

Hopefully, the smoke came from insulation burning off the internal speaker wires, and not anything burning out on any board.
Most people here would not have experience attempting anything that would cause a short out like you describe, so the only way to diagnose the problem may be to swap components one at at time. The main logic board would be a good place to start.

Macbook air A1237 short circuiting

I have just bought a macbook air A1237 the 13 inch screen - it was second hand and had a few problems.
First problem was once turned on it was show the restart screen and that would be a constant loop, managed to fix that problem so it starts and works properly
Second Problem - No battery, it wont hold charge - obvious fix replace the battery - need to do,
Third Problem - No sound, the tricky one.
The laptop had already been taken to a computer repair shop before i purchased the item - the shop is obvoiusly not competent enough to work on computers due to the fact they could not repair the restart problem (which took a non-computer techie less then 30 mins). and half of the screws from the device are missing - one on the case and all except one on the battery.
I searched around on the net for a fix for the audio and found a tutorial that said remove the sound ribbon and place it above the battery, so i did this and it worked, turned the machine off and screwed the case back together and no sound... removed the case and i had sound ?? screwed the case back on whilst turned on i had sound for 2-4 hours before it went off... Still only works when the device has no bottom on,
On anther note when i had the device with no bottom on i leaned over the machine and got a shock on my chin, didnt think anything of this due to the case being open, so screwed it all back together and thought f**k it, its a machine with no sound.
After talking to a friend who loves his apple products he mentioned that the device could be short circuiting, so i checked the electric shock on my chin again and i got one from the device and every now when using it i get one on my arm or hand??
So my question is - What could be causing the short and why is the device working properly apart from sound when short circuiting ??
Also i have downloaded OS lion - the machine is currently on OS X 10.6.8 and it will not let m upgrade? it starts the upgrade then just crashes ? any ideas?
Ps. Sorry for my spelling.

With the keyboard, if working correctly and marked as such, the "3" should also
have the "#" as an option using the Shift key. There are additional hidden keys
that these same buttons can provide, conditionally, with use of the "fn" function
key; this acts like a super-shift key in certain instances. Some keys on a main
external keyboard are condensed on a portable keyboard, & appear with 'fn'.
To tell what the keyboard can provide in various alternatives, you could find
and activate the Keyboard Viewer from within the System Preferences>
International> Input Menu. With 'visible in menu bar' activated, one can
more readily access it and the ability to tell what keys and shift, opt, etc
combinations, or the fn key, can make appear in documents or elsewhere.
The Keyboard Viewer opens into a small window on the desktop, so keys
that are pressed are highlighted on a tiny screen in there. You can also click
on the tiny keys in there to make them work in a document.
Notice the choices in the Input Menu section, as you can set it so Character
Palette and Keyboard Viewer both appear under the Flag icon in main Menu
bar in the Finder or main desktop. Saves having to open Sys Prefs to see it.
Some of the user interface points of reference change over time or between
versions of OS X. So do some names of things, esp with Mt Lion/Mav. In a
way it's good all older Intel-Macs can't run Mavericks 10.9.2. Less trouble.

When I print (both not wireless and wireless) I can print maybe one or more pages and the the print stops half way in a pageprint for 30 sec to 1 or 2 minutes - and then continues the printing
I bought the printer on jan. 11, 2011
Do I miss to install a driver or.... is there a problem with the printer?

You need to put the iPod into disk mode before it will show up on your desktop; if it is in disk mode and won't show up, open the Finder's preferences and check what's set to show up on the desktop.

Pl/sql boolean expression short circuit behavior and the 10g optimizer

Oracle documents that a PL/SQL IF condition such as
IF p OR q
will always short circuit if p is TRUE. The documents confirm that this is also true for CASE and for COALESCE and DECODE (although DECODE is not available in PL/SQL).
Charles Wetherell, in his paper "Freedom, Order and PL/SQL Optimization," (available on OTN) says that "For most operators, operands may be evaluated in any order. There are some operators (OR, AND, IN, CASE, and so on) which enforce some order of evaluation on their operands."
My questions:
(1) In his list of "operators that enforce some order of evaluation," what does "and so on" include?
(2) Is short circuit evaluation ALWAYS used with Boolean expressions in PL/SQL, even when they the expression is outside one of these statements? For example:
boolvariable := p OR q;
Or:
CALL foo(p or q);

This is a very interesting paper. To attempt to answer your questions:-
1) I suppose BETWEEN would be included in the "and so on" list.
2) I've tried to come up with a reasonably simple means of investigating this below. What I'm attempting to do it to run a series of evaluations and record everything that is evaluated. To do this, I have a simple package (PKG) that has two functions (F1 and F2), both returning a constant (0 and 1, respectively). These functions are "naughty" in that they write the fact they have been called to a table (T). First the simple code.
SQL> CREATE TABLE t( c1 VARCHAR2(30), c2 VARCHAR2(30) );
Table created.
SQL>
SQL> CREATE OR REPLACE PACKAGE pkg AS
2     FUNCTION f1( p IN VARCHAR2 ) RETURN NUMBER;
3     FUNCTION f2( p IN VARCHAR2 ) RETURN NUMBER;
4 END pkg;
5 /
Package created.
SQL>
SQL> CREATE OR REPLACE PACKAGE BODY pkg AS
2
3     PROCEDURE ins( p1 IN VARCHAR2, p2 IN VARCHAR2 ) IS
4        PRAGMA autonomous_transaction;
5     BEGIN
6        INSERT INTO t( c1, c2 ) VALUES( p1, p2 );
7        COMMIT;
8     END ins;
9
10     FUNCTION f1( p IN VARCHAR2 ) RETURN NUMBER IS
11     BEGIN
12        ins( p, 'F1' );
13        RETURN 0;
14     END f1;
15
16     FUNCTION f2( p IN VARCHAR2 ) RETURN NUMBER IS
17     BEGIN
18        ins( p, 'F2' );
19        RETURN 1;
20     END f2;
21
22 END pkg;
23 /
Package body created.Now to demonstrate how CASE and COALESCE short-circuits further evaluations whereas NVL doesn't, we can run a simple SQL statement and look at what we recorded in T after.
SQL> SELECT SUM(
2           CASE
3              WHEN pkg.f1('CASE') = 0

To see what happens in PL/SQL, I set up the following procedure. In 100 iterations of a loop, this will test both of your queries ( 1) IF ..OR.. and 2) bool := (... OR ...) ).

The F2 function is never called. What we have NOT seen, however, is PL/SQL exploiting the freedom to re-order these expressions, presumably because on such a simple example, there is no clear benefit to doing so. And I can verify that switching the order of the calls to F1 and F2 around yields the results in favour of F2 as expected.

Can you get an ipod touch 2nd gen working after a short circuit?

I was replacing the screen on my 2nd gen iPod touch, and when I was trying to lift the screen (not the glass, the display) out I accidentally and stupidly touched two chips (I think)on the board in the bottom left (the top two of the set of three brown and silver ones) together with a metal ended screwdriver, it made a quiet high pitched noise and then I couldn't turn on the display ( by pressing the lock button) , I would've turned the iPod off before hand but the touchscreen didn't work at all so I couldn't and looking back at it I really should've just waited until the battery died. But I didn't :(. Please help.

thanks, i actually checked it this morning and it was coming on to the low battery connect to power screen but the screen looked all messed up, i dont know if this was because of the short circuit or because of when i tried to take the screen out after i had short circuited it, either way i have to replace it anyway as it already had dead pixels, the reason i as this is because i dont know wether the other screen will work normally if i put it in, i dont want to fit it to find out it doesnt work.

How to aquire short circuit current from digitizer PXI-5105?

I was trying to aquire short circuit current with the digitizer PXI-5105 (it only gives me voltage). Any suggestions as to how I can make this measurements? I have gotten some hints from someone that we should use a Keithley (I have an old Keithley 237). Is this the case?
Thanks.

Using a digitizer for current measurements is not generally recommended, as digitizers are made for high-frequency voltage measurements. Why are you using a digitizer instead of a DAQ card that's made to measure current, such as the PXI-6236? What maximum current do you expect?

Problem NI 6509 DI: lines short-circuited?

Hi Everybody,
I have some problems with an NI 6509 card. I configure
Port0 as Digital Input, but while my program runs (and after....),
lines of port 0 are short-circuited, that is, I am not able to acquire
TTL signals, and, moreover, if I use a multimeter to check the
impedence between Port0-line0 and ground, I get 0! (beeeep....) And so
on for any other input digital line
   If I run max, test panels runs correctly, I have no "beep" from my multimeter.
   Thanks....

Hi Matteo,
   now everything works, I changed some stuffs....
   I use LabWindows 7, and I will keep it, because I have to
do bit maskings, bit operations, and so on. that is not easy in
LAbView, maybe because I'm experienced in LabWindows and C, while I'm
quite new to LabView.
   Anyway,there's one thing I don't like: that after a device
reset, port 0 and 1 are shortcircuited, that's not good for my
application, but I can bypass this problem!!
Goodbye and thanks!

My iMac 11,2 with hard drive and cable display problems

My iMac 11,2 with useless hard drive. Tried to replace with Seagate hard drive, but thermal connector is different from hard drive Samsung that comes with computer. I also need to replace the display cable. Any suggestions?
thanks

Hi, on the hard drive...
Tukaine
Sep 23, 2012 10:59 PM
Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor. Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable. When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
Fixes people have used in the past included:
• Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
• Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
HDD Fan Control
HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.  It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating.

Short Circuit on Inductor

Hi..
I have a simple query. How does Multisim behave to a short circuit? I take a DC source connected to an inductor. When I make it short, it should show me a msg like "The inductor gets burnt" or something like that. In stead, it shows a straignt line in an oscilloscope.
I can't prove this thory in Multisim, "A short circuit is an accidental low-resistance connection between two nodes of an electrical circuit that are meant to be at different voltages. This results in an excessive electric current (overcurrent) limited only by the Thevenin equivalent resistance of the rest of the network and potentially causes circuit damage, overheating, fire or explosion."
I shall be glad to receive the exact solution.
Solved!
Go to Solution.

Do not know if this will help, but there are components in the database in BASIC>RATED VIRTUAL. that actually simulate being "blown" by excessive current or voltage.
Another option would be to have two simulator circuits on screen at the same time. One with the fault and one without it. Hook Multisimeter/O-scopes to both circuits to demonstrate how the fault effects the voltages/currents in the circuit.
Multisim usually does not scream at you when a short occurs as most voltage sources are idea and really not affected by shorting across them. The ideal sources can handle the current within the simulator without "blowing" so to speak. I know this isn't what happens in reality, but everyone needs to keep this in mind when designing a circuit. Always be sure of the current draw from the source and wheither the "real" source can handle it as well as well as the "real" components in that circuit.
One other point. I notice you said you were using an inductor. All of Multisim inductors are ideal and have no internal resistance. Therefore, in a DC circuit they would only be a intial impedence there as the voltage was switched from 0VDC to 12VDC and then it would act as a short anyway. They are pure reactance only and this means that only in an AC Circuit would they display resistive properties. In order to model the DC resistance of an inductor in MS you have to have a series resistor tied to it.
I agree with you that there should be some type of warning that a short is occuring in the spreadsheet or somewhere.
I hope some of my ramblings have helped here.

How to connect my Satellite C650 to TV with HDMI cable?

Connecting my laptop with my television??
I have Satelite C650 laptop which isnt that old, but ive connected my laptop to the television using a HDMI cable and it isnt working.
The television is a samsung 1080p one, i would be grateful for some advice.
Many thanks
Claire

Hello Claire
I presume you use your notebook with original preinstalled OS that you got with your notebook so it should work without problems.
Connect your notebook to the TV with HDMI cable. If your TV has several HDMI ports please enable right port on TV and after doing this use FN+F5 key combination to switch from notebook to the TV.
When you use FN+F5 key combination can you see several options including HDMI option?
