I receive a blank blue screen even though my DVD players says it is playing? My tv is an older HD1080 series. I am not certain if I have chosen the correct model below. I do know it is a projection wide...


i would try other inputs and see if you can get anything. some of these tvs have a bad 9v regulator on the signal board that powers the video switch. if it goes bad, you wont get any video at all on any input, but you will still get menus and sound
its like ic9c25 its a ba09 regulator

The picture on my Mitsubishi Model VS-45607 is not staying on track and scrolling continually


Good Day,
It sounds like you have a bad cap or IC. Replace C2P05 100 ufd 16 volts, off Pin 3 of IC2P01. It is on the Signal Board. IC2P01 Part # 270P466020 (stand-up type mounted on heat sink). The Signal Board is the the board on the left hand side looking at the TV from the back. The parts are on the right side of the Signal Brd towards the middle and back. Replace it even if it checks good. Look at other Caps in the general area and if you see black stuff on the negitive leg of those caps(replace them also).

Good Luck, Big Irish.

The 9 volts power many things the microprocesser is one of them, if the voltage is dirty because a filter cap is failing color will be afected as well

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.
