Hi, I have an optiquest q19wb with a green tint on the screen. I walked out of the room for 3 or 4 minutes and by the time I came back it was green. I've checked the usual cables and ports, it's definitely an issue with the monitor. I've looked around and found guides on the internet that show how to replace capacitors on the main board. I was wondering if the issue is actually with the main board though, and if it's not, is there a place to buy a replacement video board or instructions on how to diagnose and repair the video board? Thanks!

Re: Optiquest q19wb green tint
Is there a factory reset in the menu
What happens when you adjust the color.
Have you tried the monitor on another pc -thinking graphics card.
Inside there is a cable from the main board to the panel have you cleaned/reseated both ends.Please upload pictures using attachment function when ask for help on the repair

Re: Optiquest q19wb green tint
Thanks I wasn't expecting a reply that quick
I just took a look to see if there was a reset, I didn't see one in any of the options.
When I adjusted the colors, red and green would do something,I assume it was adjusting those levels, but the blue did nothing, so I'm assuming that blue is missing completely.
I checked everything when I opened it up, there's nothing that seems out of ordinary, only a hard press will get any of the connectors to wiggle, and the vga connectors on the cable were all seated and snug. Ive tried the monitor on a couple computers and it does the same thing.Comment

Re: Optiquest q19wb green tint
Maybe a problem with a voltage regulator on the main board.
See guide on 2 seconds to black sticky at the top of this forum start at post19.
We can sometimes help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back (in the same orientation) and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.
Please do not post inline and offsite as they slow down the loading of pages.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

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.

TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... -
