I would hazzard a guess that there is an issue with old capacitors in the power supply as when they warm up the values return to near normal.
Check and change electrolytic capacitors in the power supply section.
Hope that helps.

HD channel picture is clear, but regular digital picture scramble


o.k. check all your connections
if you have a newer house check to see if you have a main hub in a closet somewhere and check all connections. Check your hd receiver and you may be able to chage the DPI the receiver receives in.

I have this problem on some of my non HD channels, also. So much for going digital. I get fuzz and pixel problems "from time to time", but, if it is really bad and consistent your should call your service provider.

Things to ask also ? are you using cable or satellite.

If satellite T.V. there are other reasons you could be experiencing problems.

hope this helps!

When you first turn it on, the picture is scrambled. takes fifteen to twenty minutes to warm up and get a good picture. Once and awhile after the picture warms up it will blink like the picture is going...


It seems that your unit has some sort of Thermal fault, either in the main circuitry or the Power Supply Unit, PSU. In all probability it WILL get worse and fail completely.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

1/3 of picture becomes partially scrambled


sounds like you have a frame fold-over fault, does banging the tv have any effect (slightly bang the set on the sides), if it does then its more than likely a dry joint, check all around the frame output chip, hope this is of some help to you

Scrambling for first 15 mins


That is the exact problem I am currently having with my toshiba 50 in. I did some reading and it sounds like there is a temperature drift across one of the capacitors on the board and it takes longer and longer to warm up. Havent fixed it yet...
