Re: e701i-a3 no picture but backlights
Is anyone good at soldering? A buddy of mine tried it but being that the space is so tight he couldn't solder the mosfet chip on for me. I'm about to order a new tcon board and I need someone to solder the new mosfet chip for me. Please have a PayPal so it can be easier for all parties involved. Please message me so we can figure it out. I'll pay for shipping both ways.

Re: e701i-a3 no picture but backlights
Alright I re-did the flash light test. No picture. I do have the back lighting that comes on. Does anyone on here have an extra mosfet chip and if so would they be able to solder it for me? An how much would they charge? I have two tcon boards. Please let me know as I'm deciding either continue with trying to fix this project or just scrap it and go spend money on a new one. But I'd much rather fix this onLeave a comment:

Re: e701i-a3 no picture but backlights
Oh yea the screen works. I removed the strips from the side and the tv was working fine for a month. Then all of the sudden tv image went out but I still had sound. I got a new tcon board plugged it in turned tv the vizio logo came on and then it went off again. I'm just wondering if someone here would be able to put a new mosfet chip on for me. I have zero experience soldering. So if someone has a few mosfet chips laying around they can be kind enough to help out. Thanks for replyingLeave a comment:

Re: e701i-a3 no picture but backlights
I have not done the flashlight test. I'm not sure what it is. Could you please tell me? Or point me to the post on this thread. I got excited with the new tcon saw the vizio logo then blank so I was sad
Well let me know thank you

Re: e701i-a3 no picture but backlights
Ok so I recently temporarily fixed the tv with removing the strips from the side of the tv. It was all good and it went black on me again but I got audio. Ordered a tcon board from eBay which I just got I plugged it all in turned the tv on vizio sign came on and it went blank again. I tried swapping and put the old tcon board an still nothing. Now is it the mofset chip or that transistor???? Also anyone who has modded the tcon board can you help me out and mod mine? I'll pay if I must. Either way let me know guys. ThanksLeave a comment:

Hey man I'm wondering where did you buy the modified t-con board for the vizio? I had the same issue followed the guide and now the pic went black again. Either way let me know thanks -
Re: e701i-a3 no picture but backlights
Well I haven't done any trouble shooting to the mosfet chip but the tv just went out on me. I did remove the strips from the right side. What else can it be? Or maybe I should just test out the chip to be on the safe side right?Last edited by Lynk783; 05-26-2016, 11:35 AM.Leave a comment:

Re: e701i-a3 no picture but backlights
Ok so what's the suggestion to solve my problem? I have the vizio 70in. I removed the strips from the right side of the tv. It worked for a month and it went back to no picture only audio. If the chip doesn't apply to my case do I just buy another tcon board? ThanksLeave a comment:

Re: e701i-a3 no picture but backlights
Damn great video. I have one more request. Where can I get the chip from? When I searched for it I got a bunch of places from over seas. I really don't want to wait a month for one small chip. Any link or sense of direction would be greatly appreciated. Thanks in advance.Leave a comment:

Hey man I'm just wondering If you can help me out here. I followed all the steps finally got the tv working back in April. But of course you guessed it the tv blew again. I do have the stock tcon board on there. I've been trying to find that chip online but I keep getting things from China an I don't want to wait a month for a little ass chip. Is there any possible way that you can send me a link on where to buy it or if you have some left over I'll buy it from you. I do have paypal. Or maybe im googling the wrong chip from the forum the chip that I saw you talk about is the QF mosfet 45v 2a sot23... -
Re: e701i-a3 no picture but backlights
Well after I followed the instructions here and I fixed the tv back in April I'm very sad to say the tv went back out and it's back to square one. Has anyone made a video of putting the new chip on the tcon board???? Can anyone help me please. ThanksLeave a comment:

Re: e701i-a3 no picture but backlights
Hey freak any chance I can get you to soder one of those chips onto a tcon board? I'll pay for your services. Although my tv is good for now because you guys are so helpful I just want a back up "just incase"Leave a comment:

Re: e701i-a3 no picture but backlights
I went ahead and removed those drivers on the right side. An now the tv works perfect. Thank you I appreciate all of the hard work and research everyone has done on this thread. Also I know if it blows again it will most likely be the chip that is on the tcon board as Bud mentioned. Thanks a million againLeave a comment:

What do you mean by known color bar source or a test pattern? Do you mean like a different dvd?Leave a comment:

Re: e701i-a3 no picture but backlights
Should I plug the right side back and unplug the left now to see what result I get? Or should I just go ahead and remove the right side drivers all together?Leave a comment:
