I've seen similar damage many times, always on TV's having the T-Con and driver boards located at the bottom of the display instead of at the top. It's often caused by a liquid spill. In at least one case, a tom cat backed up to the screen and marked it for his very own. That was obvious from the odor. Other times, it happened when glass cleaner was sprayed directly onto the screen (instead of onto a cloth) and allowed to drip onto the driver boards. In those cases, the area smells of detergent. Was there any evidence that liquid spill in your case?

Hi dear Bandara thanks for the best article you did a good job of not repairing this device and we also never repair such a device in IRAN but we will sell this for about $10 and we use the parts. good luck.

Suranga,

About 90% vertical line problems In LCD are due to this cable system technology and around 90% equipment related to this technology is going to dumping ground every year.in CRT TV you can arrange any similar size tube and replace it with without much efforts.this type of design is waste of money and also waste of natural resources also.here in India there are labs available for this type of Screen repair but question is to carry and transportation the screen to that lab is very difficult it can easily get damage in transport.

Good job, Suranga. Sometimes repairs are just not economical. Even if you did repair it, it may not last long because other components may have been weakened and soon fail thus making it more economical to just buy a new TV.

Looks like self destruct mode switched on. Chemical damage perhaps.
