Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

You possibly have a failing hi-voltage module or fly-back transformer going bad. If it has a fly-back transformer, It's not worth the trouble. Some repair shops will sell you a module. Call a repair shop for help.

Sounds like your YBL-Y Buffer lower board is going out. There are 3 boards here. The Y buffer upper which controls the top half of the display, The Y buffer lower controls the bottom half and the Y-SUS main control those two boards. They work in unison. Usually if one goes out you have to replace all. You can also get lucky and just repalce the YBL and all may be well. Now if they are vertical lines up and down the OSD-On screen display, then this is indicitive on dry solder joints on the D, G E, F boards. Hope this helps...

This is a Tcon board issue.

put a towel across the top of the tv so it can heat up faster and you will get your picture. be carefull!!

My Samsung DLP is having the same problem.  Not sure what to do, but I will contact my warranty place for the second time.  Hopefully they'll fix it.  Any other suggestions?

The cause is one or more shorted transistors either on CRT board or on main or both. The colors are red,blue and green, you have a transistor for each and a bias trans. check each there are 6 in all.
