My screen has gone black but has sound

backlight may have gone if your tv has one

Not knowing brand and model number most of these sets have a 4-5 year life and parts for a set of this age may not be available.

The risk in repairing a set this old is it may just fail again and again.

If this is an LCD TV, show a flash light on the screen from a safe distance. If you can see picture, it means the backlights have gone off and the TV might need servicing.

Show a torch light on the screen (not too close) when the TV and program is running. If you can see the picture, the backlights have gone off. Anyhow, the TV needs attention by a qualified service technician.

Wharfedale LCD3210HDAF this tv was working fine the night before .. when i turned it on in the morning the screen came on then instantly went blank .. although the sound is fine i am unable to get any on screen including menu an volume information and of course can any one help ??

It sounds like the main board or screen may have gone

Try the site www.TvRepairKits.com. They helped me recently.

Could be the power supply gone bad.
No easy solution I'm afraid.

Sounds like a failed vertical amplifier circuit. This is normally primarily contained in an integrated circuit mounted on a heatsink.
There are other possibilities along the line but the one above is the most likely.
Now all you need is a TV repair shop that is still in buisness.

• adjust brightness setting when playing tv.
• adjust screen control located on flyback transformer.
• hope this will help.
