32AV502U Front Panel LED Flashing, No Video/Audio

We had a short power outage last night and ever since my 32AV502U set will not turn on. Instead the power LED just flashes on and off in a patter of long, short, short. I have tried leaving it unplugged for hours and still no luck. I held the power button down while it was unplugged too, but couldn't get it to do anything other than just have the LED flash.
I was wondering if anyone knew of a way to fix this.
Thanks

I've got the same issue. I found this TV at the electronics recycling area of my local landfill, so I have nothing invested in it so far, except a bit of research time. I tried calling Toshiba Customer Service to see if they would tell me what the long short short flashing light means, but since it's out of warranty, they wanted to charge me $35 to answer the question. It looks like someone tried working on it already. I got Toshiba's Service Material and reference Tips document for this TV, and followed the section for Dead Set on page 5. I do get the standby 5 volts on the P802 connector, but following the flowchart to the next step, I do not get 4.3 volts on pin 13 when the on/off button is pressed. The next step at pin 14 showing less than .07V also fails. That results in a "Suspect a problem with the power supply module. There's no further module level troubleshooting that I could find.
None of the capacitors are bulging, so that takes away an easy check. There hasn't been much in the way of component level troubleshooting that I could find.

Front Panel LEDs problems for Mega 180

Hi, it's rigth one year I got a Mega 180, and I've not ended yet to tune and optimize it
I admit it's like a hobby now
I immediately ask you for my LEDs problems.
I have read many topics and maybe other people have the same my problem, also if I'm not sure if they treat about the Front Panel LEDs when they speak about the "LCD Display".
I have some switched off LEDs in my front panel, in the "time" displayng and in the volume bar: I have to substituite them? Someone have done it before? It's possible to remove the front panel or I have to disasseble all the pc
Or it's a firmware problem?
I also thank all people that cured the section of optical devices compatibility: last week I bought a new Pioneer 111D, because my LG GSA-4167B was not suitable in the PC mode, for DVD playback.
In fact I had many problems for the DVD fluently playback: I have spent 4 months trying new video codecs and also substituting the video card, then I finally have understood that was an optical device problem.
The Pioneer 111D was perfect in the PC mode, but then I had problems for HI-FI playing mode
Then I finally used my old Pioneer 108, that I had in the old desktop, and all work (I pray) fine both in HI-FI and PC mode.
I'll be very happy also to describe to whom that will ask me, my experience with the Mega 180 "assembling", during the last year, hoping it could be useful for other people.
Thanx

Initially, you might just hook your ring to a case structure to
determine which frame exe
cutes. You can put the terminals for the
Booleans in the different diagrams and about the only other thing to
keep in mind is that you probably want a delay in the loop.

Can I Bind a Front Panel LED to a specific element in an array of booleans?

In LabVIEW 2010 I have a string of LEDs. I have and array of boolean values that contain the values that the LEDs should indicate.
What is the best way to connect the LEDs to elements in the array of booleans?
Can I Bind a Front Panel LED to a specific element in an array of booleans?
How is this done?
Can anyone show sample code?
Solved!
Go to Solution.

Imagine that you have an I/O card that provides 128, 256 or 1024 digital inputs and the requirement is to have an LED on the front panel to represent the state of each digital input. This frequently occurs.
Wiring that many digital inputs individually is a royal pain and then some !
It would make sense to have one shared variable as an array of Booleans that represents the status of all inputs and then use data binding instead of wiring each individually. The individually wiring would violate all recommendations on diagram size and fan out.
Frequently scanned For loops to update all of the LEDS would take alot of CPU time.
Wouldn't it be MUCH better if PSP could be used to update the LEDs whenever the data changed (as it is supposed to do) ?
In my case I have a LabVIEW Yaskawa servo driver that provides me information about 16 servo drives that may be connected. I have LEDs on the front panel to represent some of that status for each individual drive. But Yaskawa provides the information on the drives as an array of clusters of information for each drive, which I perform some business logic on and turn into shared array of Booleans to feed the LEDs (and some banks of switches as well).
Unfortunately LabVIEW does not seem to have any way to bind the LEDs (and Switches) to individual elements in the shared array of Booleans. It is just not that smart. Even with only several banks of 16 LEDs and Switches, wiring them individually using Decimate Array of Index Array functions is a royal pain and makes the block diagrams very large. It would be much worse and almost unreasonable to do if the size of the information was much larger.

890GXM-G65 front panel - AC' 97 or HD audio?

Hello, folks. I bought an 890GXM-G65 and I am having a doubt regarding the installation. The audio connector from the front panel splits in two. One connector reads “AC’ 97” and the other “HD Audio”. My motherboard manual says nothing about which one should I use to plug into the JAUD1.
I have been researching and looks like AC’ 97 is from AMD boards and HD audio is from Intel boards. Is that correct? Should then I use the connector AC’ 97?
I appreciate any help!
Cheers,

Oh my bad. Never thought it was called a "hijack". I'm sorry for this.

Accessing front panel LEDs in several subVIs

Hi, I'm new to LabVIEW! Ok, what I'm trying to do is create a front panel with 9 LEDs. Then I have a Menu Ring, with three different options. These options determine the order in which the LEDs are lit. So what I was planning on doing was creating three subVIs, one for each of the options...but how can I do that when I only have one boolean for each LED? So basically how can I relate the LEDs on the front panel into the subVIs? I tried using globals - but it seemed like that just passed on the state of the boolean instead of allowing me to actually change the boolean in the subVI. I hope this makes sense...I'm really confused! Thanks for any help!

Controlling Front Panel LEDs

This is hopefully a simple problem, but I can't figure out what to search under. I have a program with two loops (Z Only Test and Full Test in Tester Program v2). They do not run at the same time. I would like both loops to interact with an LED on the front panel (Testing). How is this done?
Under Z Only Test, it works fine. I tried to connect it to the sequence (Full Test), but it tells me I can't do that. On odd sequences, for the most part, I would like to have the LED light (TRUE). On evens, off.

I would assume whatever works for this would also work for numerical displays as well.
No. I'm not even sure exactly what you mean by clicked on the LED "and changed it to a variable."
Right now you have only a single place where you use that LED. It has a terminal node on your block diagram within a while loop. I don't know how that fits into your overall program architecture as your VI is quite expansive. (Two tips, 1. Don't use stacked sequences. 2. Look into a state machine architecture)
All that happens at that point is your read from a shared variable called "Testing". I'm not sure from where else in your VI that you want to interact with that front panel indicator. Or whether it will conflict with the already written piece of code. I also don't know where this shared variable is written to. But the first idea is have the other sections of the code write to the shared variable and let this one update the front panel indicator.
The second idea is to create a local variable of the front panel indicator. Right click on the terminal within your code and select Create / Local Variable. But again, you will have to be careful with conflicts with the different portions of your code writing to the LED. This is also known as a "race condition".
(Yes you can use either shared variables to store numeric data, or create local variables of numeric controls or indicators.)
I'm a bit nervous about your code. It looks like you have a decent amount of LV experience as you have created quite a sophisticated VI there. However, it doesn't seem like it is easy to expand or modify. It takes up quite a bit of screen real estate. It doesn't use any subVI's even though a lot of the code seems to be duplicated or very similar. And it seems like it uses a lot of shared variables, probably more than necessary.

Front panel led connectors cables problem

Anyone knows how to connect the cables for the front panel power and hdd switches and leds to the jumpers on the board? The cables have wordings printed on one side of the cables (power led.. hdd led.. etc).. i'm not sure which side should be facing up on the board ... is it the side with the wordings facing up or the opposite side without the printed wordings ? i'm worried that i may end up short circuiting the board if i connec them the wrong way round ... thanks

The are just switches, so there is no polarity to worry about. the led's are polarity sensitive, so If they don't work, just reverse the connection; no damage will occur.

How do I derive front panel led's from kstat?

/* compile with cc enclosure.c -lkstat */
#include <stdio.h>
#include <stdlib.h>
#include <kstat.h>
#include </usr/platform/sun4u/include/sys/envctrl.h>
main()
kstat_ctl_t*kc;
kstat_t *kp;
envctrl_encl_t *enc_info;
int i;
/* initialize the kstat interface */
kc = kstat_open();
if (kc == 0) {
perror("kstat_open");
exit(1);
/* find the inode cache link */
kp = kstat_lookup(kc, "envctrl", 0, "envctrl_enclosure");
if (kp == 0) {
fputs("Cannot find envctrl.0.envctrl_enclosure\n", stderr);
exit(1);
/* read the ks_data */
if (kstat_read(kc, kp, 0) == -1) {
perror("kstat_read");
exit(1);
printf("there are %d instances\n",kp->ks_ndata);
enc_info = (envctrl_encl_t *) kp->ks_data;
for (i=0; i < kp->ks_ndata; i++){
printf("loop value : %d\n",i);
printf("instance : %d\n", enc_info->instance);
printf("enclosure type : %d \n", enc_info->type);
printf("enclosure value : %d \n",enc_info->value);
printf("********************\n");
enc_info++;
kstat_close(kc);
return 0;
Returns...
There are 7 instances
enclosure value : 208
or
enclosure value : 192
depending whether one of the lights is flashing or not. I need to know how to tell if an error light is on.
How about the disk led's?

You don't actually need to pass anything to the Sub-VI.
Within the Sub-VI you can call up the chain of "higher" VIs, i.e. the VI call chain leading to the sub-VI in question being called. From here you can wire simply the text of the VI you require to an "Open VI reference" function, get a list of the controls or indicators and initialise them as you wish. I used this a few times for a custom "Print Parent Panel" VI.
Here's a pic of an example (LV 6.1)
Hope this helps

MCS 7845-H2 Front Panel LED's

Trying to find some sort of support document for this server model to get an understanding of what the LED's mean, as one of them has just turned amber (which according to this ( http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/product_data_sheet0900aecd80572766.html ) it indicates an internal component failure.

There's no setting to adjust the brightness of the LED.
Next time you are near an office supply store, pick up a box of 3/8" or1/2" round, white labels/stickers.
Place one or two over the LED and it will dim the LED. Add more to adjust the brightness level you want.
The white stickers are virtually invisible once you move back 3-4 feet from the AirPort Extreme.
Looks much nicer than a piece of tape.

"What about buying a PCI card like the Sonnet Tango (http://www.sonnettech.com/product/tango_2.html) and then getting a generic PC hub to mount in the bay and plug into the Sonnett card?"
That's what I did.
It works fine except for one thing.
I can't use Option-boot. My mouse clicks don't get recognized correctly when I try to select a boot drive.
I'm pretty sure it's the hub. It has an NEC chipset according to ASP.

Using Front Panel Composite Video 2 RCA Jack on the HP m8000 Media Center PC

I have a HP M8000 Computer with front panel RCA jacks, composite video 2 and Left and Right Audio RCA jacks. I have been unable to determine how to select these jacks for inputting video recordings to the computer. Any ideas on how to use these jacks to input video from my VCR?

The front composite video jacks did not have software support for the release of this PC. The analog video software was not compatible with Windoze-Vista so there was no software given with this PC model that supported analog video input.

LEDs on front panel

Employed my Vista Pavilion for several years without incident until last night when I noticed the top "on/off" button which usually glows a light blue was unlit.   I originally assumed a power glitch, so I just restarted the machine to note the following:
    Fans come on and the power supply seems OK, but the system did not boot.   The screen was just black with no characters or image/background. In fact, the screen's power saving mode soon engaged indicating the video card was not sending a signal. Never get to the BIOS screens.
     Now here is what I think may be significant: the green LED and blue LED in the front console were on continuously.
Sometimes, hardware manufacturers provide diagnostic information by way of the lights (e.g., washing machines).   In other words, turning on LEDs can provide state information. Is this true with HP hardware?
Some more clues which tell you what is not the problem. I happened to have a new power supply handy, so I traded it out with the same results.   In normal operation, the green LED indicates disk activity, so I just removed the disk entirely to see if the green light would go out.   Nope, still on steady.   The blue LED typically implies the WiFi operation but I rather doubt at this pre-boot state the WiFi would be working.
I traced the power button line (two grey wires) to a half-sized board in the rear. No breaks in the wire or bad connections.
Any ideas?

Don't understand this reference to a half-height board.
The Front Panel Header (9-pin, 2x5) on the motherboard is where those front panel LEDs and buttons are terminated.
EXAMINE Pictorial in the Internet link to motherboard (above).
HOWEVER, some HP Desktop models have a front LED to show the user of LAN or Wi-Fi connections.
That wire would connect to the network card or motherboard via a different connector.
Some Media PCs of this era (2008) had Infared connections (option) for remote control of TV tuner option card.
LEDs do not last forever (have a long, but finite life) and can fail due to DC over-voltage or surge conditions (environmental, component failure).
In addition, this Desktop PC is now 7 years old .... a long-life for any desktop.
IF the motherboard has failed (component failure, such as capacitors), then replacement may be best advice.

Centering Label Text over front Panel Indicator

How can I get the Text in the Label of a Front Panel LED Indicator Control in LabVIEW 2009 to be centered over the LED?
How can I change the Font an Font Size of the Text of a Label?

Hi,
Label to be center at the object.
There are many Ways like
1) what the JackDunaway has explained Text Settings Toolbar button.
2) Other you can dynamically change the property of label.
Like you can change programmically change label justification, size, color, and many property.
Just right click on object.Go to creat property node. refer screen shot for more help.
Thank you.
