My Toshiba 42H83 has a scrambled screen for about 5 minutes when it is turned on, if it has been off for a while. Once it warms up, it works fine. I have replaced the satellite receiver but this did not...

ok, you are talking about lines in the picture, it started where it would clear up after a few minutes but now it will slowly take longer?

I know what is wrong.

The picture is all waves ,I get sound and color but the picture is all lines and waves,what part should I get??

To fix the shaky picture on the toshiba rear projection tv model number 42h83. You need to either replace the 13 capictors on the hyper module or simply replace the hyper module itself. It's cheaper to replace the caps, but you'll need decent soldering skills to do this. You can replace the entire hyper module with less soldering skills, but I believe the module costs about $100, maybe alittle more. You can find the entire fix by googleing "hyper module". Good luck and I hope this helps

You likely have a bad hyper board.  As time goes on the lenght of time it takes to get a clear picture will increase and eventually the picture will never clear up untill the part is either repaired or replaced.
