TDELEX EC2089 BLUE LINE SCREEN IN THE MIDDLE

You have whats called a verticle swep falure. Its probably just the verticle output IC but if you dont know much about soldering or circuit troubleshooting ,you should leave this to the pros. Theres way to much Hi voltage inside these sets to twiddle around inside them. Also there are no consumer serviceable parts inside these sets as well, as they are all solid state, and my advice is spend a few bucks and get a pro to do this job for ya, as it can, and will, kill ya if your not careful.. Is it worth saving a few bucks??? Naawww Call a pro.. Good Luck

No vertical deflection. Vertical output IC, caps.

Replaced vertical IC ( la78041 ??>.. Or La78040 ). Look for born resistor beside IC. Replaced capacitor 100uf 35V too!!! Good luck !!

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad
