Hi There,

Have you double checked that your scart leads are all pushed in fully, usually if a scart is out on one side you loose either picture and/or sound...

Tv was flicking took apart and cleaned now turn tv on and it go's right back off no pic. though


Hi Leanne.. since your TV was flickering to begin with, that problem still exist since cleaning it will not resolve it... as a rule, cleaning a TV by taking it apart will not solve any problems, only creat more..

Flickering of the picture us usually caused by weak signal reception and should be the first thing to check. Next check the power cord and receptacle and make sure neither are worn or damaged. Try moving the tv to another receptacle... if it still is not working correctly, probably time for a trip to the TV repair shop...

My kid put a plug from the computer no power to it and it just went off it was pluged into the serivce port


It's probably just a fuse.
I don't have a physical layout of that TV inside though so if it's blown, I'd need pics.

Here's the possible good news though.
He may have simply tripped the power supplys' protection circuit.
Unplug the TV for 5 minutes and plug it back in, it may be fine!
It takes a while being unplugged to reset the power supply when that sort of thing happens.

If the TV still won't come on, you'll need to open it up and get some good shots on the power supply board and the board that the service port is on, and of the cable that connects the 2 of them together.
If the pictures are good enough, I can point out where the fuses are.

If the photos are necessary, post a comment or reply here and I'll give you an address to send the photos to.

Tv wont power up makes a noise but no picture


Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
