There is no need to change which motherboard the problem is in the panel (in the buffer strips), if the panel is AUO, then as always the TVS diodes assemblies, take a photo of the buffer strips on the left and right sides.Attached FilesComment

Again, you can’t prove anything, watch the video to see what the problems are with these panels!

Well, we saw it, it's good that we didn't order the motherboard, and the same problem would have remained!
You don't need to install these diodes, they are more problems than they are worth.Last edited by lotas; 04-02-2024, 03:37 PM.Comment

ESD can be moved as i said before--- ... they are not JUST DIODE,,,, as they are controlled with Freq. this i wrote before,,, this freq generated and monitored by MB.-- oscilloscope will show you.. not ohmmeter. say its diy .. i will accepet it... but don't say issue or repairLast edited by Diah; 04-02-2024, 04:17 PM.Comment

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... -
hi all and hoping i could get some help please.
my philips 58PUS8105/12 has started acting weird.
its getting these lines across it and sometimes a strange black half circle sometimes appears on the right hand side edge of the screen,the screen is cool to the touch all the way around except where you get to that black halfcircle about the size of a smartie right on the bezel edge of the screen,its quite hot.
tv prob 3 years old and only used on weekends for a few hours so not done much.
i popped the back off and cleaned the ribbon contacts all to no... -
Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
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...
