The picture on my TS-4573 rear projection tv has started to roll vertically at a fast rate. How can I make this stop. On old tv's there was a vertical hold adjustment on the back that you could play with...

this fault is caused by defective electrolytic capacitors in the vertical deflection circuits, they need to be changed out, do this before it causes more problems, there are no adjustments for this anymore.

Mitsubishi Vs-60705 Bigscreen turn on vertical roll warms up stops rolling and begins jumping up and down also picture is not clear

Check C2P05[ location on convergence board]. This is a 16volt 100Mf cap that is bad. And check out C2V29 [cap value is 16volt 22 Mf.] And still while you're at it, resolder the pins on the convergence ICs.Should fix your TV!

Their is no more you can do.
Their are no "hold" controls on TV's anymore.
Power Supply failure.
NO YOu can not buy a "Powers supply"

You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

Vs5065 Toshiba

Sounds like your vertical circuit is starting to go out. Probably the capacitors in that circuit. They are starting to leak and once charged up all way and warm they are holding. But it is only a matter of time before they go out and you will have the problem permanently. You should start looking for a reputable repair shop now. In fact, if you check out toshiba's website you should be able to find an authorized repair shop in your area. If there in none then check out the shops in your area. You should find one who is authorized with at least a couple of companies. Check on pricing. You should be able to get these caps replaced for around $100.00. Some companies will also come on site (yes, there are still some people who do house calls) though you will pay more for this service it saves you from draging the TV all over town. Anyway, this is not a problem you are going to be able to fix without some real electronic knowlege.

Hitachi ultravision

Check IC601, C603 for leakage, I601 and vertical pulse detector QN05

for poor convergence check RK42 for open circuit.

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.

Picture has horiz. lines

There is no vertical hold in the tv circuits now adays. You may find a vertical center or a vertical height. Your problem sounds like (if it has PIP Thats Picture in Picture) its in the PIP module and its a small module that stands up and most models of Mistubishi this module is no longer availabvle. The problem with the module is the small pana caps are leaking and ruins the PC traces. I have heard that theres a kit available on E-Bay to jump out this module. Now if its not the PIP model then it could be a few capacitors in the vertical sweep circuit. Also the B+ feed off the Flyback that supplies voltage to the vertical output IC could have a bad or leaky capacitor in the circuit. If your not a tech or solid state troubleshooter theres not much you can do and SHOULD take this set in to a repair center. Good Luck
