Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.

SOURCE: LG 42 LCD no sound or picture

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

You have a component in the power supply that is getting hot and changing in it's value, look for bulging caps first or burnt spots around resistors.

My Vizio VW42L LCD television turns itself completely off


had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Power suddenly went out on the tv - the standby/power button flashes and the there seems to be no way to turn the tv on again.


What you should try is unplugging the tv, then push the power button. After about 10-20 seconds plug the tv back in. The tv should work now and if not, let me know and I can help you further.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives.

Solutions?

2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Five blinks is a severe hardware failure supplys not working. Viper is down. You have atleast a bad power supply board could have taken out your sustain boards. If you are good with a meter you can measure voltages and see if just your power supply is dead. If you have never handled a multimeter you will need a tech and a power supply is not cheap..Power supply is about a 600 dollar board.

My 42 inch plasma wont turn back on after power cut?


Hi,
We purchased a phillips plasma 50" in july 06 and it cut on and off 5 or more times a day I called phillips customer service they told us it was due to the cable company they came out and changed the tv jack gave us a new box and tested the lines said everything was ok. The problem still kept happening got back to phillips and they sent us a flash drive to update the info in the tv. still kept happening told us it was due to tv being sensitive to power flutuations. well we are now 5mths out of warrenty and the power board blows up! phillips will not do anything to help the person I spoke with admitted we were given bad advice the bill was estimated at over $500 so if I were you if its still under warrenty make them send someone out to look at it, Reading up on phillips tv complaints this seems to be a common thing By the way phillips customer service sucks dont rely on them to help you much. good luck
