Question about Sanyo DP42746 42 in. Plasma Television

1 Answer

We have had our tv for about 18 months. It just went off one morning, light stayed on but no picture and no sound. We took it to a repair shop and the board that has gone out is on back order and no eta of when they will get it, but it will cost anywhere from $350-$550. Include us in whatever you do.

Toshiba 32 RegzaNo picture, but hear sound


The most i have seen an inverter board go for on a 32 inch tv is about 300$ and that was shipped from japan, not having the actual part number off the board makes it difficult to lookup. I usually charge about 100$ to do this type of replacement. so they do seem a bit overpriced, considering it also may just be a bad capacitor or 2 causing the board to fail, they run about 5$ each. If you have another repair shop in the area i would call them and shop around. If everyone seems to have the same amount of price in mind, it may be just time to get a new tv, with the release of the LED HD tv's the prices for lcd are dropping drasticaly , you should be able to get a much larger one for the same price as you paid for that one .

No Picture


I am deeply sorry but you will need to replace the backlight bulbs. These are not available.

Look on Ebay for a 32" JVC with a broken LCD Screen. Buy it and use these bulbs to fix your TV. I am sure there will be a few good ones in the broken TV. It's that or list it on Ebay for $50 and expect to get about 200-300.

LCD Panel repair for this problem is $500 for parts so you are stick with repair yourself or sell.

HELP PLEASE Vizio Plasma tv broken again - possible driver board?


This could cause by the power supply or the mainboard.

- If the LED stay Green when you turn on the TV. But you can not turn it off, in this case the main board has failed. Replace the mainboard will fix the problem.

- If the LED light always stay at Orange, you can not turn on of off. In this case the mainboard also has failed.

- If you turn on the TV you will hear the power supply click on the LED is green then it click off the light turn Orange. In this case the power supply has failed.

Which boards did the repair shop replace?

Hope this will help.

Samsung le32n had it for 16 months came down this morning blue light flashing on bottom of tv but no picture or sound. Tried swapping cables, sockets, leaving it off for a while nothing helps


Those Samsungs and most other HD units can fail within 6-18 months of purchase.. I would contact Samsung and go up the corporate ladder for help. Otherwise you may be looking at a repair bill that is as high as the cost of new unit.

Power light comes on, but no sound or picture


I had the same problem and my tv was out of warranty. I took it to a local repair shop and they told me didn't work on that brand. They said they charge $300 minimum for labor, plus parts. So probably at least $500 to fix. 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 data1.gif ribbons. We disconnected the data 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, but no picture. We then disconnected the buffer PCB's from the Y-Main 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.
