My coby flat panel television won't turn on, at all. No light, no sound, nothing. I've already tried unplugging it and plugging it back in. Even given it a rest period. Please help.
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.

Most likely you will have to replace the power supply. It is a very common problem especially in newer electronics. You can test it with voltmeter or multi-tester. They tend to get worn capacitor inside the power supply due to cheaper parts

Power-cycle the unit (turn it off and unplug for several minutes). If you're unable to power the unit on successfully, the TV probably requires repairs. In home service can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

If theres absolutely no power and no lights on, it sounds like the fuse inside the t.v.. It is pretty easy to change. You have to take out the screws on the back of the t.v. and take the back cover off. Look for a 3/4" glass tube fuse and see if the tiny wire in it is broken. Pop it out and bring it to radio shack and get a new one. Put that one in and try it, Make sure the t.v. has been unplugged for at least 2 hours before opening it so the capacitors have time to drain. They will hold power and could shock you if your not careful. Also, dont use anything metal to take the fuse out.

Thanks for the solution, I'm wondering why they don't just build these things with better parts though.
