    that was really great advice being that after i wrote the to get advice i realized that the tv had 2 power buttons thanks

    I have pressed my POWER button manually, but no sound or lights responds. I have tried plugging the TV power cord directly into wall outlets that I know work, but still nothing. This TV showed no signs of problems the night before (5 years old).



    Sometimes I turn off the TV using the remote control, which only turns off the cable box & sometimes leaves the TV light on (standby light?), but appears to be off because the screen in black. I wonder if I have caused the power supply to go dead sooner by doing this?



    I have a 36" Panasonic tv about 5 years old. I think it is the power supply that is dead. I have just called a tv repairman and told him that I think my power supply is dead... he is charging $60 just to come look. I wonder what a repair like this should cost??? any ideas...

I would have to say you have a dead power supply. You will want to make sure first that the "MAIN" power switch located on the lower left on the rear of the unit is turned on as well. Without that on there will be NO standby light.

MY TV WONT COME ON


1. Make sure AC power is on at the wall socket. Check your circuit breakers to see if one is tripped that allows power go to the wall socket.
2. Check your TV power cord and plug in to take sure the cord is not broken or damaged and that it is properly plugged into the TV.
3. If you are using a remote, replace the battery and see if the TV starts to respond to the on off button.
3. I assume you get nothing on the TV, pressing the menu button does not show the menu. If you do get something, try reprogramming the remote.

ViewSonic N3250W will not turn on


Do you get a red standby light at all? If not, I'd look first for the standby transformer as being defective. There may also be a fuse right by the AC power cord. Look around inside and update this with your results. Post whether or not there is a standby. We'll need to go step by step on this one.

That is the classic symptom of GPU damage caused by overheating. Seek a GPU re ball repair.

Magnavox 37MF23ID, would not turn on. Power button only blinks (green light). We have switched power cords and nothing happens. No picture, no sound.


if the power light comes on but the screen stays black, then your TV might be on the wrong input Channel. for example: you switch inputs when you play games or watch dvds vs. watching regular tv. Try to change the input

I have a Sony Bravia LCD tv an it won't turn on at all the standby light is not even there I've tried turning on an off and leaving unplugged for an hour still nothing.? Help,


You either have a problem with your power supply board or main board. I would start with having the power supply fuse checked as well as the power supply board!

The power on my Toshiba isn't working.


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_17_2012_8_14_45_pm.jpg6_17_2012_8_15_04_pm.jpg

No standby light


Depending on the brand and MODEL number here is what I think happened.

All TV sets have a Standby power supply. It runs all the time even if set is off but plugged in.

It supplies among other things the power (usually less then 12 volts DC to run the remote circuitry---It usually is not fuse protected so if a strike hit nearby it may have come in via the power cord.

Trouble is almost certain to be in the standby supply.
