Re: shaking screen

Check the 9v regulator Ic2p01 on the signal board for correct regulation 8.9 to 9.1 volts. If voltage at the output is under 8.9v, replace the regulator Ic. Always replace C2p05 100 Ufd 16 V on this set and that should take care of the shakes but you may want the tech to go ahead and ESR some of the other troublesome caps throughout the Tv. He'll know what you mean. Many of the 100mf caps replace automatically. Several others will have a questionable ESR and should be replaced. Caps are inexpensive, but probing with an ESR meter is somewhat labor intensive so you miht discuss with the tech just how far you want him to go testing for bad caps.
A Mits is a great Tv and this repair is clearly worth it..

Zenith z56dc1d dlp tv picture works for about 1 minute then starts shaking and tv shuts off

You may want to get it in a rather warm room and or remove rear cover and use a hairdryer to warm everything up inside the Cabinet--with rear cover off look to see if the fans are dirty etc and if they all come on, if a DLP especially look at the lamp itself and the fan that cools it.

Screen shakes / jumps vertically on my Sony KP-51HW40

The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

TV picture shaking!!!

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.

Shakey Screen

That problem is caused by defective capacitors on the Hyper Board location UZ01 stamped MVPU14. You will need to have a technican remove the board and replace all the 10 uF @ 16 Volt SMD caps p/n 24619040N found on that board. The Hyper board is no longer available as a part.
