Question about Toshiba 50HX70 50" Rear Projection Television
My TV is going on 7 years old. No problems other than a convergence problem 3 years ago that was fixed. Now I have a picture shaking issue going on. The convergence seems fine and needs adjusting every few weeks with the weather. The picture shakes when first turned on then seems to settle for awhile. Thanks for any suggestions or help.
It sounds like the Hyper board is begining to fail....Does the menu shake too?

You have a Hyper module problem.Very common with these chassis.Toshiba part # 23148024.This part is no longer available,but it can be repaired.I dont know how much electronics training you may have but it`s a pretty detailed job.The hyper board is the silver stand up module inside the unit right behind the external Audio/Video jack panel.There are 11 little capacitors that all need to be replaced.The value of these caps are 10uf @ 16VDC.I do this job for about $245.00 and the unit works fine.Check with your local shop if it is too much for you.If you don`t know what you are doing you can ruin this module then it`s time for a new set.Good luck.
