42" Sanyo HD Plasma TV (Model DP42746)

Premtech,

I just read about someone having problems with their Plasma TV. I just took my TV from the repair shop and they told me that I need to have the Y-Main Buffer and both upper and lower buffer boards replaced ($600.00 which is a bit crazy).

I was watching my TV and all of a sudden the picture went out, the green power light still comes on but no action as far as a picture.

I have the Samsung main board (LJ41-02759A). I see that you guys fixed the problem for some one else. What do you suggest and how much $$ are we looking at?

Thank you,

Scott Morgan

Scott,
Not at all crazy! The Samsung/Akai lines seem to have numerous problems with their Y and Z sustain boards and upper/lower Y driver boards (aka buffers). That and power supplies are generally the largest percentage of the problems in those units. That said, I'm a bit confused looking at the p/n you referenced. I don't see that as being a Samsung number belonging to a Y-sus board. Usually they start with BPxx-xxxxxx..
Lastly, while you might have every ability to replace the Y-sus board if the buffers are bad and you don't replace them you could simply burn up the sustain board when you power it up... Installing the buffers is a bit more complex than the sustain board so be really careful there...\
Good Luck
Bill

No video but audio is fine on Sanyo 42" DP42746 TV


If you unplugged the Ysus board, then you need to replace the Ysus board, or both sustain boards. This is the part: The part is often available on Ebay, or from manufacturer. Look also at Vance baldwin or Partstore. To do a good job the Sustain boards should be tested by a tech , following service manual. It is almost for sure sustain board by the way.

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.
