Re: e701i-a3 no picture but backlights

All,
Small update. TV is fixed by replacing the transistor on the T-Con board. $.78 and I have 3 extra transistors after replacing the original and previous owner's transistors.

Kevin,
If it's the same issue that this topic focuses on, those three boards being replaced will not fix your problem. You will end up replacing two good boards and frying your T-Con board again. Read through this post, i know it's long, but it's worth it if you want to save money....

Gabe,
Be sure to unhook one side of driver tabs before you power it on with the new board. If you have a multimeter, you can check the new board before installing to ensure it's good. Then if you're super thorough, you can unhook both sides of the drivers, test the voltages on the T-Con(I would say unnecessary if it passed bench test).

If you unhook the right side drivers and get no picture, that's your good side.
If you unhook the right side drivers and get a "weird" picture(see my pictures above). that's...

Re: e701i-a3 no picture but backlights

First off, great post. Lots to read through, but very informative. Acquired a 70" vizio with no picture. Followed the posts, right side display drivers seemed to be the problem. Detached right side drivers, still no picture. I may have left the TV on for too long with the new tcon in while troubleshooting. I'm getting a short on the "bottom right" pin of the transistor. Here's the question: Replace the TCON again? or just the transistor?

Or: Am I missing something that would warrant a retest?
