I think its a main input board. Looked at all the compacitors and diods and never seen any pointed tops. It is almost like it is using the intellsensor to adjust the screen. It works great with no problems when you use a USB Jump drive just viewing pictures but when you are using any other input cable compon RCA HDMI Cable still flashes or blinks. I will change the main input board once i get on on ebay and match numbers. I will keep you posted on the repair. These videos come in handy when trying to make an easy fix. There are only about 5 main parts in these tv's They all have certain jobs to do so It should'nt be that hard to pinpoint the problem. I had one LCD tv screen black but had sound screen jet black was TCON Board fixed for about 20.00 part on ebay. Any help is greatly appreciated. |
