It takes about 5-10 minutes to warm up, then the picture is fine. While warming up the picture wavy and jittery untill it warms up. Is this a picture tube issue?


You have bad capacitors in the power supply or around the 5v & 9v regulator circuits. If you have a meter just measure the outputs of the regulators. If you don't know what a voltage regulator is or does you should call a qualified repair shop. Estimate repair cost $250

The ic IC9C25 is a 1 amp 9 volt regulator, see
IC REGULATOR 9V 1A TO252-3 TR - BA09FP-E2

The multimeter must read an output voltage between 8.45, and 9.45 , if it reads 1.7 then the IC is faulty.

Check the datasheet here

Mitsubishi projection tv vs60va2 picture rolls


This unit has chroin bad caps on the 5v, 9v and 12v regulators. If you know circuitry you can check thos caps and replace the weak or open electrolytic caps. If you call on a tech that services mitsu. this is faily common repair for them and should not cost over 150.00 to 200.00 depending on your area.

My vs45607 has problem


Theres a leaky capacitor on the 9V regulator output line. If you don't know what I'm talking about, you probably shouldn't try but it should be a fairly reasonable repair by a pro. Good Luck

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..

Picture is Rolling..stops after some warm-up


I have seen this many times. There is a 9 volt regulator on the small signal board that causes this. The regulator goes bad and the 9 volts starts dropping, especially at start-up when the regulator is cold. If the voltage is below 8 volts then the picture gets dark and the vertical becomes unstable, with the picture squeezing down and/or rolling. As the regulator warms up the voltage starts rising back towards 9 volts and the symptoms start clearing up. There are 3 regulators in a row on the board and the regulator in the middle is always the bad one. Replacing that regulator should cure your problems but it should be replaced by someone experienced in servicing Mitsubishi projection TV's because pulling the chassis out is quite tricky.
