    Power has shut off completely - won`t turn on at the top or with the remote. We replaced the batteries in the converter as we had been having trouble changing channels a few weeks ago. Now, nothing. TV is 18 months old!!! Help.

SOURCE: won't turn on

These units have a separate switching power supply that does indeed get very hot. What I have found is that a 1000mF@25v capacitor goes bad in the power supply and needs to be replaced. If your set's red power light turns green for just a second and then turns back to red without the set turning on, this may very well be your problem. You can either try to find another power supply (make sure it's rated at 12v-5amp) or take your old one to a repair shop. Be very careful if you decide to try a repair yourself, switching power supplies can pack quite a punch.

SOURCE: DVD input channel reads "no signal" when I try to play a DVD

First I would run a dvd cleaner in unit! Second you could take tv apart and look to see if signal cable is loose. the power wire seem fine as it powers up, and accepts an eject dvd.

SOURCE: Proscan 26LB30Q Vs PS2 = HELP

The red white and yellow cables are composite connections. The red/green/blue connections are component connections.

The playstation's composite connections consist of two audio connections- red & white, and a composite yellow video connection. The TV's white connection is the audio, and the red/green/blue are component video. You need an adapter that will connect the one yellow(composite video) to the three red/green/blue (component video) connections

When i plug my new tv into the sky box via a scart, the tv picture is distorted and a major buzzing noise is coming from the tv. sky have checked and said the box is fine. when u connect to another tv it...


Have you tried another scart lead? Also tried all of the tv scart sockets? Don't try and cure this by using an expensive upmarket scart lead, you'll just be wasting your money. The cheapest leads work just as well when the function correctly.

You could also try reversing your current lead by swapping the tv end to the Sky box and vice-versa, as there are many leads which cause feedback issues, and also a lot of "cut" leads (designed to prevent feedback looping) which must be fitted the correct way around. A "cut" lead is one where the wire to pin 19 at the tv end and to pin 20 at the video/Sky box end has been cut.

Note that scart leads MUST be fitted with the tv and Sky box switched off to avoid damage. Most people (including professional installers) regularly ignore this precaution though.

If all else fails then take the tv back and exchange it under the Sale of Goods Act; it's certainly not uncommon for new tv's to have faulty scart sockets.

If I've solved your problem then please take a moment to rate my answer. If not, then please report back with the make and model of TV and I'll try a more specific answer.

Power switch turns on and off


that would work if you want a costly bill. Try this before dishing out cash, the problem is the switch that tells the board to turn on and of is bad and a cheep quick fix is to open the back of your TV(#15) (unplugged of course)and remove the hex(#10) screws to the mother board look under TV tube and you will see the switch board,remove both hex screws(#10) and pull the switch board out,follow black cord to mother board and pull cord out of its port. know find the word KEY also #2 on the switch board, should be the red wire. cut this wire and be sure there isn't any bare wire showing at your cut, a piece of black tape will help this. reinstall the switch board and mother board and back of TV . you should be all good to go

TV switches its self off when I turn on.


Protection circuits usually cut in when you have power supply issues and too much current. U might want to start checking out your power supply for bad components.
