what do you mean when you say resistors look like they were dry??

did you try fixing the wires? i would do that first and see if anything else is bad.

SOURCE: will not stay on

FIXED IT!!!

So if you have a blinking red protection LED:

Turned out the pico-fuse for the -23V had 130 ohms resistance. Initial continuity test feature on my meter indicated it was good since anything under 200 ohms is continuity. All of this after many hours of frustration... and not understanding why all secondary voltages on the power transformer were at 50% for the 2-3 seconds of power up before shutting down.

The "leaky" pico-fuse turned into resistor allowed enough power to illuminate -23V LED despite voltage being 1/2.

Replaced with new pico-fuse to get true -23V. All other output voltages followed suit and TV is working perfectly.

Don't trust the green LEDs. Measure all voltages and be sure to verify 1 ohm or less for every pico-fuse.

I don't understand how a faulty -23V rail would cause this problem. Feedback is from the +31V rail which powers standby 12V safety regulator, 9v and 5v switched regulators.

Anyways it works now.

Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where, if otherwise,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help to solve the problem.....

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

When I push the on button the green light comes on for second or two then goes out.(will not stay turned on long enough to even get a picture on the screen.Mitsibishi Model # WS-55315


This set has a self check feature--if set has been unplugged it clears the error buffer--plug in and try to turn on set.

When green light comes on and then goes off ON THE FRONT OF THE SET press and hold BOTH the menu and input(device) buttons at same time for at least 5 seconds and release both buttons.

Power light will blink a 2 digit error code like 2 blinks, 2 blinks, a pause and repeat the code for a total of five times.

Let me know what error code you find and I will explain it.

Mitsubishi WS-65908 will not stay on


Its a color convergence problem from description:

If green light comes on for a few seconds and goes off:

On the front of the set (not the remote) press and hold both the menu and input (device) buttons at the same time for at least 5 seconds and release both.

Watch power light: it will blink a two digit error code, in your case I suspect it will be 2 blinks, 2 blinks and repeat several times.

Let me know error code and I will help.

Screen went black. Shut t.v. off and tried to turn it back on. Power comes on, front light is green, and in about 3 seconds the t.v. shuts off, green light goes off. Was playing dvd at the time. Shut off...


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix. SD TECH

I have a sony tv model kdf-50e2000,and it has a problem with the picture going blank,the only light that on or flashes is the green (POWER) light. when turning the set on the green light blinks as it...


You tv used lamp XL-2400 or also known as F93087500. It is very common for this bulb to fail and have the exact symptom you are experiencing. I cant count how many times I have seen it.. Replace the lamp with either the exact Sony or an OEM and you will be back in business..
Good Luck!!

The tv just turns off after about 5 seconds and won't stay on. i've used the system reset and unplugged it already. no power surge, lightning storm, etc. Ideas?


If reset does not cure it and if after about 70 seconds of unplugging set the green power light stops blinking, do this:

When power light comes on and goes off, on the front of the set press and hold both the menu and input buttons at the same time for at least 5 seconds and RELEASE both buttons.


Power light should blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it four more times.

Let me know what error code you find and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

Power will not stay on


Based on the model number WS65511, this set has a self check.

Turn on and when green power light goes out:
On the front of the set press and hold BOTH the MENU and INPUT buttons for at least 5 seconds and then release both buttons.

Power light will blink a two digit "error" code.

The most common is 2 blinks, a pause and 2 blinks. Set will repeat the error code at least 5 times.

Let me know what error code you find and I will tell you what it means, I hope you find it is 2,2 as that is the most easy to fix.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
