Check all micro-fuses in power supply.If two or three are bad,a convergence circuit O/H will be necessary.Pro help usually required-chassis pull,replace convergence IC's and careful hand-
soldering needed to prevent call-back.

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
