Just replace the T-con board

That answer I agree makes no sense.

Most of these sets have NO vertical hold and if did it will not cause the lines.

A brief educated guess:

Set has a main board that communicates and controls the screen--tests for that are not simple (checking waveforms with a scope and signal generator).

The model indicated here is a DLP that uses a lamp (let me know if model listed is not the one you have).

In DLP sets aside from main/digital board you also have a optical light engine---it processes all signal in and out to the screen.

Optical engines do fail and cause some simple and some complicated picture issues.

Some will even cause the set to "lock up" with a picture or strange looking screen---clue to this is you have to shut the set off by pulling the power cord.

The set may be old enough they do not really want to help you or even talk about it.

I looked up how to fix red horizontal lines on a Philips flat-screen tv. It turns out it needed the Y buffer upper replaced. I am not sure if this problem would be similar but it might help. I am also searching how to fix a fuzzy screen on a DLP tv. Hope you find what you need.

the lines are from the vertical control, theres a minor short on the vertical board if not fixed the power supply will short and whole tv will go green call repair shop and get short fixed

You need to replace the digital board

Please let me know if you find a fix. and what the problem was. Eddie.

need the modle number to see if there is a service flash or fix/

No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.

Get DMD board part # and shop for best price.......
I will do the same......let me know.....T.
