If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

SOURCE: I have a 42 LG Plasma TV with a broken screen

NO....You must pay attention to all numbers on the back of the TV. Verify these with your tech or contact your LG customer support for the correct board numbers. If the screen was broken I doubt if you can repair this for less than it cost to replace. The screen for this one runs at about $650.00. Good Luck and good advice!

I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I

The picture goes out after about 10m min in use stays off ffor about 5 seconds then comes back on, it does this several times while watching a program


This fault suggests that you have a bad joint somewhere on the tv. If you feel competent to do so,remove the back and check all lead connections.If secured ok put power on and wait for fault to occur and when it does, listen for any arcing or strange buzzing noises coming from the power supply. If so, there may be a dry solder joint on the power supply. Also check for bulging capacitor tops with possible brown fluid discharge on the central power supply board..If this is present, replace the capacitors..Samsung plasma tvs are prone for this, and if ignored, eventually the tv will not come on at all and keep tripping on and off.

Dead set, Akai 42" Plasma PDP4294, no power


Porblem solved,
It's a wonderful day.... Ahhhh, it is now FIXED and working great. I found cracked solder joints on a few of the switching power transistors and some of the big diodes and other heat producing parts. Also notice that the infamous Red caps C524 and C523 were discolored but they checked OK on my cap meter and also my ohm meter, however while I was inside the set after removing 1 million scews I decided to replace them anyway.
I hope that my repair success helps someone.
