Has anyone found these power supply boards. I believe the Polaroid LCD uses the same power supply. Andrews Electrionics has a part that uses this number and is a power supply. The part is $166.00. However, it is a special order part and cannot be returned if it is the wrong board.

I have a Vizio LCD TV. The TV powers on but white horizontal lines flash across the top third of the screen and then eventually vanish. Even after they are gone I have no picture. What's wrong?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

It wont turn on at all


Good day to mam wendy311!!!!


If you TV is totally dead set and no red light or green light on the front...


if that so the problem could be cause of dead set power power supply board...

You have 3 choices its either repair it on your own or took it to the technician or buy a new set of power supply board..

But for me I suggest to buy a new power supply board because if you took it to the technician cost of repair is almost or higher depends on the bad parts than the new power supply board...

But before you buy a new PSU please check this simple and common parts that usually cause of dead power supply board..
  1. Transistor----Check if shorted
  2. Capacitors----Check if bulged or leak.
  3. Resistors----Check if open or change value..
  4. Fuses---------Check if busted..

I hope this solution will be helpful..

Thanks for using fixya...

When I turn my TV on there is sound, but, the picture vanishes after a couple of seconds. Why?


The backlight inverter is what powers the screen to "light up." You will need to check your power supply for the proper voltages going to the backlight inverter. If those all check out ok, then you need to replace your inverter to get your image back. You can find a new inverter by searching "inverter + model number of your tv.



Please rate if this helped :)

Unfortunately in this scenario the only way you can fix your TV is by calling a technician. It sounds like your power board is failing and you will need to replace that in order for it to function correctly again.

My Sony WEGA kv-32" TV


The "D" board is the main circuit board assembly containing most of the set's power and deflection circuitry. It's the board that typically causes most of the problems because there's so much on it. Unfortunately, this board is no longer available from Sony as a part, and must be repaired to the component level. Many shops don't want to (or can't) get into that depth of repair, so they quote a high price on board replacement. There is no single part you could order to repair this board yourself, I'm afraid. There are some companies in the business of repairing boards, but you're still looking at $200 to $300. With the price of a 32-inch LCD set now around $300 to $400, there's no point in trying to fix a TV when it's just a few dollars more for replacement.

The tv picture vanishes and there is multi-colored lines on the screen for a second then shuts off and then will turn itself right back on and it will keep doing this


I had a similar problem with my Phillips 42 in. LCD HD TV.

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. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
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.

Hope this helps

No power with remote or manual power switch


Your convergence module is probably bad. It is a plug in module, so labor would be lower if the convergence settings are still good. The bill would be about $300.00 If not, the labor for convergence would add to the bill. If the whole job needed full convergence the cost would be about $500 to $600.
