Question about Sanyo DP42746 42 in. Plasma Television
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
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
42' HD V4 Y-MAIN

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

If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.
If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.
If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.
When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.
If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.
