Probably the Horizontal output is shorted. this is a 3 legged Transistor on a heat sink at the back of the board.

My old 'sharp' tv is not turning on, it's plugged


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.

TV worked fine for 12 years till this evening. When I push the power button there is an electronic clicking sound inside but the set will not turn on. The speaker still makes the quiet popping sound it...


The tv has a high voltage problem, sets that last ten years or more have come to the point where a new tv should be considered, because even if you fix it there is good chance something else will go wrong, remember the parts are twelve years old.

I have a solution for The United States of America! "If We Don't Make It, We Don't Need It".

Personally, I believe if we went back to actually manufacturing things in this country and stopped importing everything, a lot of these problems would STOP!

Think about it America!

Cant turn off panasonic PIP


To turn off the "stuck" pip on a Panasonic tv without a remote, turn off the tv. Then hold down the "Action" button on the front of the tv and press the power button. This will activate a reset and self check of the systems and voila! The pesky pip screen will be gone! This is on an approximately 10 year old regular crt "CT-xxxxx" series tv.

Try holding the volume up and channel down buttons on the set at the same time. Give me the model # if that doesn't work.

Trinitron KV-36FS13


The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply. You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset. If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set. I hope this helps.
