LED TV That I’m Not Able To Repair
The complaint of this 32 inch LED TV was white screen with color vertical lines in a square box as seen from the photo below:
Before I opened the TV casing, I already knew that this kind of problem was usually due to the LCD panel, ribbon cable or the T-con board.
Once the cover was removed I could clearly see the power supply board and the mainboard while the T-con board was covered by a metal casing-see the photo below:
From the visual inspection it seems that all the circuit boards were fine until the panel board was exposed. I was shocked to see this kind of problem-see the photo below:
The panel PCB ribbon was burnt and this was my first time seeing such problem after had repaired many LED TVs throughout my repair career. To add salt into injury the other side of the panel board was also had problem-see the photo below:
I told myself there is no way to repair such problem unless if I have the Tab bonding machine and the parts but then again to repair such problem it will be very costly and I’m pretty sure the customer would not be willing to pay for the high cost of repair.
I can say that, even if you have the machine, it will not be 100% working after fixing the new ribbon because there must be a cause of why the area was burnt.
If you have read all my previous repair articles, I’m sure you can see the success in every repairs that I had posted but not in this case where I’m not able to fix it due to the reasons that I have mentioned above. If you have any comments about this situation I really would like to hear from you.
