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

50HDX82 rear projection Flicker/Fuzzy and Vertical Purple Lines


The hyper module itself is not an expensive repair about $70 to $100.00 dollars. The tech will simply be replacing about a dozen 16v/10mf smd caps and re-installing it on the signal board. But that doesn't address what he has to do to get to it and get the hyper board off and back on the signal board and that is a bit time consuming.
What I would suggest is to call around to the various shops and ask what they charge for the hyper module repair and see if you can get an off the cuff estimate for around $250.00 dollars.
If you need help finding some reputable shops try TVrepairpros.com for help in finding some of the best technicians available.
