Jumpy / Schrolling Picture...?

My problem started last night. The picture on the screen started "jumping" almost like the cameraman was running when filming? Now the picture "schrolls" a bit down the screen and then back up. The picture on the right seems a bit blurry at times too. The TV is about 4 years old, but it's only been used for the last 2. Are there any suggestions?

Re: Jumpy / Schrolling Picture...?

This is a problem of synchronization.  are there any adjusting knobs in the tv set (vertical hold adjust) if  yes you can try but if none maybe consult a technician.

I have a 57 in toshiba rear projection, picture just started jumping and went out, if you put it on another imput for gaming the picture is there but is rounded and is jumpy could you tell me what is wrong...

Possibly not repairable, because many problems are related to a board called the "hyper" board, which is mostly no longer available.-- Most picture problems other than convergence or a bad tube, which doesn't sound like yours.

Picture looks like it is jumping

Sounds like a vertical sync issue on the chassis board. However you also mentioned the picture moves left to right or vice versa which would suggest a horizontal sync issue. Either issue is not repairable by the DIY. Sync issues must be isolated using test equipment usually found in repair shops. My suggestion push it down a hill and enjoy the show then go buy that flat screen you almost purchased last week.

Black and white screen...

The color wheel can cause a black and white picture but not the jumpy or negative look.
Those symptoms are usually caused by the DMD assy which drives the color wheel and is somewhat expensive, most of the time you can purchase the whole Light Engine which includes the DMD assy for the same price.

Jumpy Picture on Hitachi 55FX48B

On older Hitachis the most common jumpy picture is loose connections on the vertical output IC. If you can tap on the main board and get it to act up then this is most likely the situation. I believe the location is IC401 and is located toward the front of the set on the signal panel. Not too tough to repair if thats all it is.
