Re: intergrated tcon board ic rt6939 vestel polaroid p55up0277a
do the 3 files have to be in a folder,
or do i load them on to usb
as 3 separate items?
ive double checked the voltages on U11 and U13
and as you say i would expect them to be the same?Leave a comment:

Re: intergrated tcon board ic rt6939 vestel polaroid p55up0277a
are you sure the info you wrote on yours photo below are 100% correct, both SPI had same No.25L1606E ?
try the firmware from Arıza Notları
while the tv ON, plug it from wall socket.. put all files on usb drive and insert it at any usb ports, press OK on the RC and keep pressing while you plug the tv in wall socket again... hope your screen will show progressLeave a comment:

Re: intergrated tcon board ic rt6939 vestel polaroid p55up0277a
heres voltages from u13:
1 3.25v, 2 3.2v, 3 0v, 4 0v,
5 0v, 6 0v, 7 3.1v, 8 3.1v .
so no volts on pin 3 and pin6 compared to u11Leave a comment:

Re: intergrated tcon board ic rt6939 vestel polaroid p55up0277a
if you check page 14 of document you can see 1&2 lvds options. U13 is Mboot SPI not MFC.
U14 is position code of MFC ic.
Vestel dont allow access to firmware of export products. I have full firmware of
QNDS2DN12 panel : https://yadi.sk/d/QyY2xVD8ghxQYw
all my respect.Leave a comment:

Re: intergrated tcon board ic rt6939 vestel polaroid p55up0277a
arizanotlari... the schematic you upload here are for ONE CHANNEL LVDS. as the set of OP. MFC SPI U13 not U14..
do you have recovery firmware of this set with 3 files???
i have MFC.bin used by vestel such 246009 & 240226 which used over most vestel.Last edited by Diah; 11-15-2020, 09:03 AM.Leave a comment:

Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
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... -
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... -
Good afternoon,
I have a Polaroid P43D300.
It shipped with WiFi and Bluetooth.
Two weeks ago, I ran through the first time installation.
This did a full reset and went through the first time setup.
Once complete, I went to settings > sound.
selected Audio Link, changed setting from disabled to enabled, pressed green button on remote and the tv does a search (discovery) for Bluetooth devices.
search completes and doesn't find any devices.
I have tried everything I can think of.
Can someone provide... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
More Details
TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
