Does anyone have a schematic for the signal board that is attached to the panel? This is the board that is connected to the panel and goes to the T-Conn board via a flat ribbon cable. I have something shorted on the Left board as it blows the fuse on the T-Conn when I hook up the ribbon to the left signal board. The right side of the panel has a perfect picture with its ribbon cable hooked up.I need a schematic.

Most failures on that tab bonding board are due to shorted cap, so start checking the resistance of the caps.Never stop learning

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 everyone, newcomer in this forum, i watched tons of video from Sorin, i like the way i calmly explain things, i did quite some console repair, i am not that bad at micro-soldering, but troubleshooting where the issue is, is definitely where i still have progress to make. Usually i was able to fix the console because the failure was obvious, or because i was able to find someone with similar measures on the board and was pinpointing what to replace that way.
Nevertheless, let's say, i don't come as a total beginner.
I have this old laptop, which suit perfectly my needs, with the... -
Hi there!
I have a Sony Bravia KDL-40Z4500 which shows a colored vertical stripes pattern when turning on, with a central black shadow that slowly dissipates within the first 10 seconds.
Photo of the situation after the black shadow dissipates:
After this behavior the red LED will blink 9 times, then pause for a bit, and blink again 9 times, in a loop.
I checked the manual (available here) and this corresponds to "HFR error", quoting from the manual:
> This indicates HFR Communication error. [ HFR Communication...
