Does anyone know what the voltages should be at the test points on this tcon? I'm mostly concerned with TCON VID1 which is reading 1.1v which seems strange to me.

Re: Insignia ns-50dr620ca18 (NS-50DR620NA18) tcon voltages
Dose the one marked V1D8 read 1.8 voltsWilling to help but I'm no expert. -
Re: Insignia ns-50dr620ca18 (NS-50DR620NA18) tcon voltages
So it looks like VxDy is the voltage at that point x.y volts so it looks like V1D1 is correct at 1.1 voltsWilling to help but I'm no expert.Comment

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... -
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.

Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... -
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... -
Another eazybone post
took on this OLED now.
Symptoms. Hit power, white light shows briefly and then 5 blink red code. TCON issue per chart on first picture.
I'm thinking I have a power board issue though, which is one of the options
Now to check pin voltages from PSU to main and PSU to tcon
Pic 2
1 tcon on 12 -- 0v (when I hit power this goes to 3.1 stays for short time and back to zero)
2 bl err -- 0.16
3 evdd on --0
4. Ac off det 3.187
5 power on -- 3.362 BUT fluctuating randomly to 3.352

Hello guys,
I have a Philips 240B7QPJEB. The monitor seems completely dead.
I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
The weird thing is, that the Power LED is powered over the TCON board.
