I will first target the Main T-con board IC.Ĭonclusion- All customer are different.

If more time is given to me, I will perform an in-depth checking on this faulty board. Once the new board is replaced, the problem was gone and this had proved it was indeed the T-con board was the main culprit. The problem now is that my customer need this TV back urgently and I got no choice other than to buy a new T-con board from Ebay and fixed it-see the photo below: My guess was that one of the main T-con board ICs could have problem. Initial testing of basic components and DC supply voltage were found to be good. This means the problem is either due to bad components, Improper DC supply or signals and etc where I need to troubleshoot and find it out. The T-con board now is clean and I had to hook it up to check if The TV will get back to normal.Īfter putting everything back and powered it On, the problem still remained the same-see the photo below: Next I reflowed the ICs with a SMD rework station. What I had done was to clean the board with a brush and sprayed at the connectors with a contact cleaner.

I took out the T-con board for visual inspection and found that one of the LVDS connector area had ant’s nest-see the second photo below: From my testing, the faulty part was the T-con board. If the OSD menu appeared then you know the problem is not in the LCD panel and T-con board is the cause. In order to confirm that the LCD panel is not the cause of the problem you can actually press on the menu button.

This kind of problem can be caused by bad LCD panel or faulty T-con board. This 32″ Videocon LED TV came in with the complaint of many color vertical lines across the screen.
