    Olevia 265-t12 -LCD display problem

    This was a great place to turn for this TV before so I hope you can help with my new problem. Recently I replaced the inverter board because a transformer went bad again. Once I got it running I checked the backlight and my 2 seconds to black problem was gone.

    So I reassembled it and connected it to a video source and now my display is messed up. Basically if the TV display were cut in half vertically and also in half horizontally to give you 4 equal sections, the top two 1/4's look fine. The bottom left corner is mostly good but fades where it meets a completely blacked out section.

    At first I thought that I had broken the LCD but the lines are too perfect for that to be the case. There are 4 ribbon cables, 2 each on the top and the bottom center. Could one of them be off? I had them disconnected before and the TV shut off without them connected. Could I have damaged the LCD and not cracked it while moving?

    I didn't get any feedback on this so I thought it might help attaching a picture of the problem. If anyone thinks I would be wasting my time trying to repair this or could tell me what you think the problem might be I would be very grateful.

    Thanks!

      That looks like it could be a panel problem sadly. There is the chance a t-con board or main board could cause it.

        The curious thing is that it was working just fine when the transformer on the inverter board went bad. I bought a new inverter board from ebay and installed it. Reassembled everything and then this. I think I will take it apart again and check the connections. I will post back if I fix it.

          Just in case anyone else runs into this I want to relay the fix. Begrudgingly I took this thing apart for the umpteenth time. I checked all the connections and tested with the same result.

          I inspected the ribbon cables and they looked good. I pulled the ones on the bottom where the black square was and carefully put them back checking each left and right pin to ensure its aligned. Tested and boom it was fixed.

          Put the thing back together and now I just need to get some help to put it back on the stand. The thing weighs 250-300 pounds. Such a pain everytime I need to work on it.

          Thanks for looking and hope this helps someone in the future.
