If a power loss someone needs to open set and see if when power came back it popped the line fuse, follow power cord inside to the fuse which it goes directly to.

There is a fault condition in the TV. Safety circuit shuts it down.

SOURCE: RCA L26WD12 26IN, LCD TV will not turn on, the red

It can be due to unstable DC power from the power supply due to bad caps, or bad main board (I had to replace my main board, and later on the inverter boards). You may want to think about putting money into this TV.

I have a Panasonic 46" flat screen plasma tv that will stay on for as long as you want, but when turned off, will not come back on for hours


If the set is a few years old you might want to look at the caps in the power supply--not unusual for them to be puffed up and hence cause issues like this.

My 46" rca


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 tobuy and 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.3_24_2012_2_45_20_pm.jpg

No sound on my 1997 rca home theatre tv


have you checked in the menu to see that the speakers have not been switched off if you have a sattelite or cable box try unpluging the for 10 mins and plug them back to the ac and do a fresh restart many times that clears up loss of sound issues if not then you will most likely have to call a servicer in your area for further assisatnce

TURNS OFF ALL THE TIME


Hi


Thanks for using FixYa. You’ll need to reset the Projection TV and to reset it follow these steps:


  1. Turn off the television and wait for 5 minutes.

2. After 5 minutes unplug the television power cord from the electrical outlet.


3. Let the television remain without power for more then 1 minute.


4. Plug the power cord back into the electrical outlet. If the television is plugged into a power surge protector, remove it from there and plug it directly into the wall outlet. Turn on the television. If the issue is resolved, then the problem is with the power surge protector and not the television.




If the issue is not resolved then this might have happened due to over-voltage. Please check the power supply unit for swollen/bulged capacitors and burnt wires/components on the power supply board of your TV. You should try and turn off the TV for 8-10 hours to reset it. Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition. All this is only recommended if you have electrical expertise and know how to solder/re-solder components.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Needs to be cleaned


The back comes off the unit.  Lots of screws.  If you do this, DO NOT touch anything related to the tubes.  Power it off for several hours...unplugged...before touching it.
