Most likely cause is the power supply board inside the set has failed. I suspect that as it is dead--could be a fuse but a fuse makes no sound when it fails--if you cannot open the set to look take it to a good shop and have it examined.

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.6_2_2012_12_46_56_am.jpg6_2_2012_12_47_12_am.jpg

Not making it on or out of standby---first place to look is the power supply for signs of damage or puffed up filter caps there.

Calm down, Calm down! Your power supply board is at fault. On the power supply, you have a bad diode. Location of this diode is D639. Replace it with an NTE 5087A. Thanks for asking, Matt of Martins TV Repair.

Component input won't work


There are 2 rows of RCA connectors on the back of this TV.
If you are looking at the back of the TV, on the right side you'll find the connectors.
On the bottom row, left most RCA jack is the Video in for the Component video.
on the top row, the right 2 connectors are for Audio connections.
we put the Yellow plug from our Wii into the bottom row video connector, and the red and white RCA connectors into the top row plugs.

This enabled us to connect the Wii, and play games.

ry changing the input device to something you are sure, works such as a DVD player. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.
