Question about Televison & Video

I own a Sanyo DP42746 Flat Screen Plasma TV. After 3 years the top half of the display periodically blanks black. Is there an easy way to fix this or does the pdp display need to be replaced? Is it worth replacing the display?

    This is an intermittent problem. I have read of this problem with the same model TV. It occurs periodically with my TV. I am attempting to head this off before it becomes a failure.

    So there are no bad wires, loose connections, or moisture involved or incorrect wiring.

Hi


Thanks for using FixYa. Unfortunately it is not possible to contact a specific expert however; I can provide the required assistance. To start with you’ll have to open the back of the unit, then check the power supply board and check for bad components. As the power supply board develops high voltage to supply to all components so you should check that board for any bulged capacitors. If still the issue is not resolved then the issue might be with Y-sustain or X-sustain board. These boards are located on the right side of the unit. Check for any high power sources near the TV or any cordless kept near the TV. These things can also affect the working of TV. Loose connection inside panel or some output chips are gone bad. Also check that there is no moisture behind the lower front molding which might have corroded the small electrical connections. Don’t allow moisture to run down the screen. It may also be caused due to incorrect wiring in the TV or the wires that run to and from the TV. Please check and replace whichever is required. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Hi,
Top half of the display periodically blanks black shows that problem could be in panel drive boards located on either sides, visual check by qualifier tech is needed to identify what board is causing problem and luckily all boards of PD42746 are available in Shop Jimmy on reasonable price so repair would not cost you too much.
Call local tv repair shop and ask them to replace defective board as replacement would be available with Shop Jimmy.
Hope these info will help you.
Thanks.

Black screen of death - DP42746


I am a military spouse and our same tv did the same thing on Super Bowl Sunday 2009! We did everything we know to do: call the company, called the repair man, etc. There apparently isn't a solution to this that wouldn't cost more than the tv is worth. So I got an attorney to start a class action:

If you would like to be compensated for your TV please contact me @

Danimimozi@gmail.com


There are no fees or anything to do so.

Black screen on my sanyo


Call Sanyo. The 800 number is on your remote. Insist on talking to a supervisor and you may get somewhere. I had to do this and Sanyo called today to tell me to take my tv to the shop. They are paying for parts and I have to pay labor to get it fixed. Repair shop said $35.00 to look at the set and if it's just to boards that need to be replaced, it wouldn't be too expensive. We'll see.

Sanyo told me they haven't gotten many complaints on this tv, DP42746, 42" Plasma. You guys have to call them and complain.
