Question about Sanyo DP42746 42 in. Plasma Television
I have had a 42" sanyo dp42746. last week it went dead. green light will come on and off with remote but screen and sound are dead. if i unplug is and plug back in it will come on breifly. i notice once it is dead the click from the relay(?) is missing when you push the power button. assume this is the problem but what to do?
Ok Fellas I found the Problem!
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.

Hey all guess what?
We bought our 42746 brand new from
walmart in Jan. 2008. hmmm. Looked Serial number up on sanyo and it says it's out of warranty. Well I don't think so. I, for some strange reason believe I read "one year return" to retailer for exchange. THEY DON'T MAKE THING ANYMORE!
Box didn't ever look to be opened at anytime AND this tv wasn't even on the shelf, it was in the warehouse.
Ours is doing the same thing, green light, no picture, or sound. Now I think I'm going to have a little bit of words with Sanyo in the morning. I really don't want a flippin 50" plasma, the 42" was hard enough to get up the stairs.
We'll see about it in the morning.

I had the same problem. the TV comes and my tv was out of warranty. I took it to a local repair shop and they didn;t work on that brand. they said it would be $300 minimum for labor, plus parts. So probably at least $500. Since I figured we had nothing to lose my buddy and I took it to our shop at work and decided to take it apart and look for any obvious problems such as blown fuses, burned components, etc. All of the printed circuit boards are connected to what appears to be similar to a motherboard via data ribbons. We disconnected the data input ribbon of each PCB to the microprocessor PCB and turned on the TV. Each time it turned back off after about 3 seconds. When we disconnected the Y-Main PCB the TV stayed on and I got the sound back. We then disconnected the buffer PCB's from the circuit to ensure they were not the problem. Finally, we pulled the fuse on the Y-Main PCB and reconnected the data ribbon and the TV and sound stayed on again. I found a site that sells the Y-Main for $179 and I am deciding whether to try it or not. Any suggestions or comments would be helpful.

I was told by the TV repairman that the main assembly board went out - quoted $500.00 to fix. Still fighting with Sanyo to pay, they told repair shop that they would verbally, but never faxed the authorization paperwork. Basically, Sanyo told me "too bad" since warranty expired two months ago. I told Sanyo that this is more than a warranty issue -- they have a product that is known to be defective and they didn't recall. Their are a hundred other complaints on the same model. Has anyone got their problem resolved?

We made a huge mistake by purchasing this TV. It was the same thing picture out with the little green light. I am trying to get it fixed and no one will touch it. I even called the geek squad and they said that it wouldn't be worth the money, they also said that they no longer carry sanyo because problems dealing with the company and the replacement parts were no longer in stock anywhere! I spent $1500 just to have a piece of junk. If anyone comes up with any solutions please let me know.

Please let me know what your repair shop says. I am holding off on fixing my tv for now.

I currently have my TV at the repair shop, we'll see what the problem is, I don't know if it is worth $500 to fix a 'cheap' branded TV with a history of failing when you can get another TV with the same specs for $900 or so.
