Rolling horizontal (colored) lines instead of picture; audio OK
We have sound (on all channels), but instead of picture we have horizontal "rolling" colored lines. Is this something we can repair? Should a "pro" be contacted? Or will it cost more to fix than it's worth?

The convergence board is shot you going to need a new board as the horizontal ic's have given out. Reapiring this would take expertise and cost you more then its worth then just get a new convergence board. Thanks and please do rate.
That problem is caused by failed Capacitors on the signal and FMT power boards. which is a very common problem for mitsubishi TVs. There are repair kits available for the V26 dlp which contain the capacitors and instructions on how to do the repair. Heres a link check under the repair kits category. http://servicemanuals.vstore.ca/
Yes, the lamp will gradually get darker as it nears it's end. The rolling lines sounds more like the set is on a local channel for the cable hook up. If your local area has a channel 3 or 4 live terestrial broadcast simply tune the cable box output to the other one, the same for the tv. If this is cable/local broadcast issue it will go away in Febuary when the NTSC broadcast ends.

is this a horizontal black line going up or down? if yes, this sympton is caused by a trouble in the integrated circuit or in the vertical oscillator circuit.
this symptons has 2 variations. one is the intermittent rolling of the picture. this referred to as the "loose vertical hold" the other variations is the continuous upward or downward rolling of the picture
