Re: telly wont srart up?

It sounds like you have a problem in the power supply or a short somewhere in the unit which is causing the power supply to stay in the standby mode to protect it. You say that it won't start with the remote, and I know this is simple, but it certainly would not hurt to try the controls on the unit, just in case the remote or pickup has a problem. If that doesn't work and you have repair skills, know how to use a DMM and check transistors, as well as knowledge of TV safety issues, you will have to troubleshoot the unit. This could be a shorted horizontal output transistor, a bad power supply or a short somewhere else in the unit. If the HOT checks bad I would replace the transistor and flyback and check all the associated components for any problems. If you find the HOT bad, that is probably your problem. If the HOT checks good, you may be beyond your skills and need to have the unit looked at by a qualified tech. That's your call. Good luck.

SOURCE: TV keeps turning itself on and off, onto standby

I managed to find a local repair man who fixed the problem. He put in a new transformer.

SOURCE: black box on screen

Try unplugging your tv for a few hour/days to let it reset itself to default. Hope that helps.

It sounds like you accidentally enabled a zoom feature or something similar.

Most remote controls should have a clearly labeled "zoom" button or a "picture size" option. If not, go into your TV's menu and look for something zoom related.

If this doesn't work, just go ahead and toy around in your TV's menu. I strongly suggest writing down the default settings so you can go back to them if you screw something up.

Good luck!

Suddenly no sound & no picture overnight: is my TV dead?

If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

Has sound, no picture, just color

usually if the tube has gone you will get no sound and all you will get is the telly on standby so the best thing to do is take it to repair shop and they should tell you for free what is wrong but usuall it costs more to repair than it does to buy another one sorry i couldnt be any more help

Tv is on stand by but won't 'fire up'

I don't know the age of your set but I've found some Panasonics with a loose connection on the heat sink (an aluminum plate standing vertically on the circuit board) of the regulator IC (chip). The IC gets its ground through the heatsink. If the ground is open the power supply puts out too much voltage and causes the set to go into shut down. I've found this problem several times.

Sound fine, but absolutely no picture?

it seems that your tv has a problem in horizontal circuit (with sound but no pictures). since you moved your tv from one place to another, the tv might have shaken causing to loose some soldered components particularly in horizontal circuit. if u have exprience in this stuffs, try to resolder the circuit, if not, bring it to a service technician.
