Jumping lines throughout the screen affecting quality of picture


You didn't say weather the lines are verticle or horizontal, but if the lines are verticle check the circuit for a weak capacitor or if the lines are check the horizontal circuit for a weak capacitor. During your check check for cold solder joints, idf you come across ant re-solder then. Good luck.

Screen rolls and jumps


look at the back of your tv and see if you have anything in relations to verticle hold or horizontal hold. it would look like a round piece with a flat to put a flat screwdriver into . this way you can adjust your screen etc.

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!

I cannot find vertical hold


The sync is automatic. There are no knobs to turn. If the picture is rolling, look first to the source connection and make sure your tv has a solid vertical sync connection. If you are using the RF input then the issue could be within your small signal board also known as the SSB. Good luck.

Verticle hold transistor?


The vertical hold keeps a normal picture from rolling either up or down. You don't have a normal picture (raster) here.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace.

Good Luck!

The picture rolls vertically sometimes.


I would check the capacitors in the verticle deflection circuit. Also try resoldering the verticle output as well as the verticle yoke pins where they connect to the chassis. Mitsubishi has had some trouble with their capacitors, you may have one that is leaking. Let me know if I can help you further.

Picture Jumps/flashes for first 5 minutes


There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.
