I have a Vizio e701-a3 that very seldomly will show a image on the screen. I normally have to unhook panel ribbons and reseat to get anything. When I do see a image its very distorted and almost pixelated even though it's a led. I know this model has known panel issues, what's chances a tcon would fix it.

Re: Vizio e701-a3 tcon or panel?
Well from what I've been dealing with it very well could be a bad panel. Try leaving one ribbon cable connected to the screen at a time from the T CON instead of both and see if you have a picture that looks somewhat normal
Do you have horizontal lines throughout the screen?Last edited by freakaftr8; 09-16-2015, 09:34 AM.Did I leave the soldering iron on? -

Re: Vizio e701-a3 tcon or panel?
Unhooking either ribbon cable does not show a picture. I cant get a picture at all now, think i toasted tge tcon. Someone fill me in on "the operation" please...Comment

Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with... -
This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
My goal here is to be able to use boards on hand to swap into faulty sets when the faulty board is not obvious.
I will start by asking what is the format of the output from the mainboard and is it generic in any way or does it vary by manufacturer and/or model ?
And as far as I know a tcon and panel must be a matching pair because the timing of the signals and the voltages required to drive the panel are specific to the panel itself. (That may be a blanket statement that isn't true in some cases where the panel creates its own sub-voltages on its panel boards?)...01-06-2024, 01:32 PM
