Sounds like Back - light problem.Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis.If you wish to get some details; check the site linked here.Surf the site with patience.Pull up older posts.It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS].In such cases, the power supply board might need replacement.To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself.If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board.If this is the case, you have to replace the main board.

My Sanyo HD TV power light comes on but no picture and no sound.


Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My sanyo 47 in TV is broken and its the main board and it has no sound or picture and I was wondering if I order the main board will that fix the problem


It is possible. That is about as close to an answer as you are likely to get without someone checking out the tv for you. If it is the main board at fault then replacing it should resolve the problem.

Vizio Model E470VL, HDMI ports are not functioning properly.


on some TV's the Analog board is where the other cables plug into. I know on a Sanyo I am working it looks like the analog and main digital board are all the same. but they are just hooked together. I bought an analog board for less that $30 from Shop Jimmy.com. The prices might vary according to the make and model of TV. need to be careful and remove the back of the TV . and get the part # directly off the board. BE SURE TO UNPLUG from the wall outlet first. Nearly all the boards carry a charge even when unplugged so be careful.

TV WONT WORK


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.

Sanyo plasma 42 TV Turn off for no reason


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.
