PSU FAULT BAD CAPS

Thanks issue resolved

There are 2-3 z sustain boards at the bottom of the tv. reseat the ribbon cables first and ten if it does not change replace the board.

A black and white picture suggests you are trying to use a composite video input but the TV may be NTSC format while your game is PAL, or the other way round. Use a game with the correct format or use the separate RED, GREEN & BLUE inputs (may require a different type of lead).

Could be the screen itself. If so, change the TV. Good luck, Serge.

You have to programme the correct code for your TV into the Sky remote.

You can get these via "Sky Active" (if your box is connected to a phone line) or from the Sky website, or google search: "Sky remote codes".

However your sky remote wont necessarily control more recent televisions unless you have a REV8 remote control. You can check this by taking the battery cover off your remote and looking at the sticker inside. If it says RC1600/00 you're probably not going to be able to control your TV. REV4 and REV6 are more likely to work - but not guaranteed. If it says REV8, then you are probably not using the correct code or you're not programming the remote correctly.

If you have REV8, the correct code for your TV (according to Sky) is: 0678 or 1678 or 0254

Please rate my solution if you find this helpful. Thanks.

Does it turn the TV on and OFF? If yes, is it only some of the buttons that won't work or all of them? You said the batteries are good, but are the contacts on the remote where the batteries are seated clean and not showing signs of corrosion? If it is a touchpad issue, open up the remote and inspect the rubber oad and the circuit board for foreign deposit. If so, use alcohol and clean and dry with a soft cloth or Q tip. Hope this helps.

Changing the setting s to english only makes all the set up words in english. There is no way you can change the program audio to another language.

Check in the menu of the set to see if you inadvertently have set the screen size to a "zoom" mode. There are some sets that have fill & stretch features to make the 4:3 picture full screen and these can cause cutoff of the normal wide screen format when on those channels.
