Good Day;

Sounds like you have circuitry problems. I would recommend that you call an Authorized Service Center and come out and give an estimate. Without Model or Brand I'm sorry I could be more precise.

Good Luck, big IRISH.

Tv wont turn on


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.5_17_2012_3_16_10_pm.jpg

Bad caps that are puffed up on top- look in you power supply inside the set to see if you have this common issue.

TV screen is black but power button lights up. No


you need to open the tv up and take out the internal fuse or fuses...go and get the right type of fuses...(the fuses will be made of glass and the same size of a plug fuse) DO NOT USE PLUG FUSES....if that fails then you need to take it to the tv repair man

Not power not picture or sound


If its Dead Dead ,that mean no power is getting past the fuse :> then it needs a fuse
.30 vs 300.00-400.00

Ok there is a way of telling if its posibley
just a fuse . First no blinking lights ,good
no clicking sound from the set when you
try to turn it on .good

now unplug the set for about 30min
the plug it back in slowley if you
see and or hear sparks coming from
the plug , this is normal but bad news
for it being just a fuse , if you dont
see or hear a spark its likley just a
5-8 amp fuse blew inside the set. :>

Hope this was helpful

TV will not turn on


Good Morning Chris,
OK, first of all lets unplug the TV and wait 15 minutes for the High Voltage to discharge.
Remove the back and follow the power cord to the power supply. Somewhere around there you should find a fuse. (there may be more than one) get a bright light to look inside and try to find as many fuses as you can. Remove each fuse one at a time and check them with an ohm meter.
If you don't get a good solid reading on any of them replace the fuse or fuses with the exact same rating. Even if you get a reading and the display is jumping around and will not stablize, replace the fuse. Usually a good fuse taken out of the circuit will display a good steady reading on the meter.
I hope this solves your problem.
Have a great day!

No power no lights good fuse...


Try a different power outlet? Possible shut down of DC supply due to short circuit can be heard if listen close at back of TV on plug in or power up with remote for a quick squeel then ticking sound or tick tick tick and nothing.

Can't get full power on


I have this exact same issue; search engine took me here. I have been experiencing this problem for about a year now. When you power on, the RED standby light goes out, the power light turned GREEN, you might hear a small pop sound, then the RED standby light goes back on. YOU HAVE BLOWN A FUSE. My problem is this is occuring much more frequently now and I'm going through fused like crazy. So I'm looking for a long term solution. To replace the fuse, turn off the standby power switch on the front. Unplug the power cable. Open the back panel. All logic and power modules are on the bottom of the cabinet. Therer is a large power module in the middle. In the middle of this module are 3 fuses. The one that typically blows is the one in the middle. It's a 5 amp fuse, but double check the rating before replacing. Good luck, Mark
