Question about Sanyo DP42746 42 in. Plasma Television

2 Answers

TV WONT WORK

Green light comes on But nothing after that. No picture no audio. So I took it to 2112 Electronics, INC in (Grand Junction CO.) They did a diagnostic look at it. they said three panels need to be replaced at a cost of $500.00. This TV is gust over warranty. I payed over $1,200.00 for this thing new from wall Mart. I don't have money. I went in debt to by this TV. I don't have $500.00 To rebuild it. I will put the part, or parts in my self if you could tell me what I need and how much. Need a little help. Thank you. My name is Monte. Im starting to think Sanyo could become a bad name to My friends and family

I was lucky to get a tv repair shop that was a Sanyo authorized dealer to talk to me about this issue.
They told me that they had 3 of these tv's in and they said they were all repaired by replacing "3" parts. they are:

the Y SUSTAIN Board - Part # LJ92-01200a
the Y-Upper Buffer Board Part # LJ92-01202a
and
the Y- Lower Buffer Board Part # LJ92-01203a

I am in the same boat. I amd going to rip the back of my tv off and verify the part numbers. I HAVE NOT REPAIRED MINE YET.. so take this for what it is worth. The Repair shop gave me this info because they were going out of business and did not intend to take any new tv's in for service. The girl who gave me this info read it out of the service repair tickets from 3 Sanyo DP42746 tv's that had the same symptoms as my tv.

Please post back if any one has taken action.

The Problem is the V4 Y-Main Board. This board is located on the left side of the case looking upright from the back. I spoke with may suppliers, and Sanyo all confirming this. Apparently it has been an issue for some time. Sanyo has replaced the V4 Y Main board with a W1 Y main board in newer models. The W1 Board is NOT compatible for us tho. Just to be sure... If your T.V is taken apart (like mine) Disconnect the peripheral cable from the V4 Y Main, and turn on the set. I bet it will power up with audio and channel function just NO picture. When you plug the board back in... POOF set shuts down. Replacement boards are VERY hard to come by. So Happy Hunting!

42' HD V4 Y-MAIN
PCB: LJ41-02760A LJ41-02761A LG92-01200A BN96-03352A

Oh yeah.. just FYI, Sanyo, Phillips, and Samsung all use the same parts. Hopefully that will help your searching.

Most likely the power supply board needs to be replaced. It could also be the T-con board or less likely the display itself.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

It sounds that the IIC Bus circuit shorts bey some faulty components connected to it. The troubleshooting work to this section circuit is very skilled one. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.
