When i turn on my tv it is all scrambled for about 5 to 10 mins, then it starts working. Then after about 1 min it starts getting scrambled every 10 secs until the screen goes crazy and starts bouncing around.

Re: What is wrong and how much is it going to cost?
It sounds like the Picture in Picture PC Board. Its a little stand up type board that has a bunch of small capacitors on it and it goes bad just the way you descrbed cause its clipping the sync out of the video. I dont was told it wasent available anymore and there was a kit available to jump out the board on ebay somewhere. If you know electronics then you should have no problem locating and possibly getting a part from a shop that may still have one BUT if you dont know the insides of the TV set get a pro to assist you as theres a lot of voltage kickin around inside of a set even when its unpluged. Good Luck

I am not a TV man. For mine I turned it off, un-plugged power cable. held the "ON" switch down for 5 min, to dissipate the current in the capacitors. then re-plugged the TV and it working fine. I am not a TV repairman. Big Al
There is a part inside
the TV that needs to be replaced. If the TV is 2 years old, then the manufacture warranty is over. If you have an extended warranty, you can get the TV replaced. Otherwise, you're only hope is to call Memorex to see if the problem is a known issue with your model which could mean they're willing to do something for you even though the TV is out of warranty.
The biggest problem with their TVs is part availability. Under their warranty, most TVs are simply replaced not repaired, so they don't have many parts available for purchase. Then there is the fact that even if you can purchase the needed part, the cost of the part combined with having a TV repair guy install it for you would exceed the cost of a new 19" TV since prices have fallen so much in the last 13 months.
Don't bother taking the TV to get it "looked at" because all of the repair shops will charge you a diagnostic fee just to determine the problem. This fee ranges from $50 to $120. Since you already know the total cost of repair will exceed the cost of a replacement TV, why spend money that can go toward that purchase?

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
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...
Sounds like from what your describing, a horizontal sync problem and there are a few capacitors in this model that does cause that. If your not a tech this is something you should mess with as the way to trouble shoot this problem would be by using a scjhemetic, a isolation transformer and an ocilliscope. its a possiblity that you could also have a tune rproblem thats giving the sync separator circuit a weak sync pulse from the video its putting out. Good Luck
