Sylvania 6842pe blew fuse, replaced fuse, and nothing,no lights, noise, nada. replaced power supply board with the chord attattchment and still no power, no lights, and no noise. Was wondering could it be a diode or do I need to replace aux power supply.

There is short circuited component/s at its main power supply regulator board. Check and replace them. It is best to replace the circuit board as card bassis, rather than trying to repair it.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

• No video, Power light is on or blinking.
• TV is making a clicking noise.
• TV takes a while to come on
• Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.



Capacitor being replaced! Fairly easy DIY fix.

Hopefully only your power supply is to blame. Then you can repair it or get it repaired for a little more than $150 or get it replaced for about twice as much plus the cost of labor. If you or a repair person start testing the boards and see that one or more of them have also failed then the cost of parts and labor will go up. It looks like Encompass Parts has parts still available for this television and the power supply is $194.

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.

hello, you need to check the power supply board,check for any blown fuses or burned parts.that should be your first step. and if you don't have any repairs skills call the serviceman.
good luck

it isnt a fuse, if your fuse was blown, it wouldnt even turn on, even for a second, it is your Y-SUS board, you can order one through there website, i think

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

I hate to tell you this, but they all do it. I returned mine and the replacement does the same thing.

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
