You see the live help tech support? They should be able to give you the details, Im not sure what kind of adjustments are needed or not. So try that or repost the problem if not solved.

Why wont my tv turn on


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

I have a sylvania LC200SL8 which went dead. Repair shop said it needed a new "Mother Board" (pn A7140UH) which I replaced. Still does not work at all. Any suggestions?


Power supply voltage outputs should be check first before anyhting else is replaced. I see that it has one main board which has the tuner, inverter, power supply all in one. What do get right now?

When i turn my 42 inch plasma sylvania on, it makes a sharp high pitched squeal, then shuts off. it does this repeatedly, whats the problem, and how do i fix it?


You have a short on one of the drive boards making the power supply squeal. You will have to unplug each board until the squeal is no longer there. Which ever board it is will have to be replaced. Thanks for using fixya.

After i turn on tv- it turns off right away by itself


That board has the Sylvania part number 1EDM10583 and the price is about right. It might also need some adjustments after installation. Sylvania has no circuit diagram for that board. The TV was assembled by Panasonic and also was used in a Magnavox model. Panasonic may have had the power board designed and made for them by someone else. A technician would have to have some very good luck to repair a board like that without a schematic. Sometimes board rebuilders like PTS have the capability of repairing a board like that. You just have to ask them.

Power Supply


No. They are entirely different. Panasonic was the supplier of the 6842PE and Funai was the supplier of the 6842PEM.

Switches off


You have a power supply problem ,most likly the main board will have to be replaced, My best advice is to call out an authorized Sylvania dealer because if you make a mistake on what board is bad, they will not take it back. Play it safe. Good Luck
