Re: e701i-a3 no picture but backlights
Yes that is correct, and by picture i just meant that i saw half of the screen black and half white.
Also im not for sure what is going on with the boards on the right side of the screen. Any time i touch or bump them the bottom half of the screen gets distorted. I was able to get a somewhat clear view of "no signal" but i had to hold the board at a weard angle for it to show up.
Do you think there might be a shortage in one of the ribbons leading to the sceen?...

Re: e701i-a3 no picture but backlights
Ok, so i decided to re-seat all of the connectors along the sides of the tv just to be safe. After doing so i found that the power in the t-con board no longer drops to zero with only the right side connected (looking at it from the front).
I was also able to get a picture on screen where half of it was black and the other half was white, but i didn't have anything connected to the tv.
However, the left side is still causing the zero volts in the t-con board.
I also tried what you mention...Leave a comment:

Re: e701i-a3 no picture but backlights
yes, the only cable o have messed with are the two white ribbons on each side of the tv and the two connecting to the bottom of the t con.
I also checked each of the tabs on the left and right sides, but they look perfect to me (compared to the pics that i have saw of bad tabs).
Any advice?...Leave a comment:

Re: e701i-a3 no picture but backlights
Ok, after testing the voltages with the panel connected, i found that with only the right ribbon disconnected, all power in the t-con board dropper to zero except for the 100 cap which only drops about 1 volt. With only the left side disconnected all of the power in the t-con board drops to zero including the 100 cap. But with both sides disconnected i found that the power stays the same. Do you thing any of the components on the bottom board, such as any of the resistors, are bad, causing it not to work?

Re: e701i-a3 no picture but backlights
Yes i did the ribbon thing and still didn't get a picture, i'll be sure to check the voltages while the ribbon is connected. Should i be looking for the same voltages?
I originally bought this tv for $60 and the guy who had it before said that he replaced the t-con board once, and it shorted out again after a few seconds. Once i bought the tv, i just replaced the transistor on the t-con boards that he shorted out, but still haven't had any luck....Leave a comment:

Re: e701i-a3 no picture but backlights
Ok, so i bought new transistors for three, bad t-con boards that i had. I connected them as per the instructions on this form, but still, nothing but the back light comes on. On each board i get the same voltages: 15.60v on the capacitor in the bottom right, 1.20v on 4R7, 13.30v on 100, and 3.30v on 3R3... yet I cant get any kind of picture to show up.
Any Advice?Leave a comment:

Re: e701i-a3 no picture but backlights
Hi, i'm trying to fix my 70 Visio. I was wondering if you still have any resistors left that you would be will to part with? Also, how is your TV doing...still working?Leave a comment:
