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

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... -
I have numerous Creston TPS-2000L touchpanel home automation devices, which incorporate a Sharp LQ5AW136R panel. They all exhibit the same fault. They are about 10-15 years old.
The fault can be seen in the attached photo. Basically the displays are all washed out, to be point of being unreadable.
Clearly it's an issue with the panel. But my question is whether it's just aging related (e.g. all the pixels in the LCD wearing out) or whether it could actually be a more specific component (i.e. one capable of being individually replaced). I've seen suggestions on other... -
Hello all!
This post will mostly just act as documentation for my undertaken troubleshooting steps for this TV. Advice will also be appreciated for things to try next
Picked up the TV in thread title from a retail returns auction, symptoms were as described. I started my troubleshooting attempts by shorting the 19V PSU rail to the 3v rail with my multimeter... Doh. Big spark, dead PSU, TV not turning on anymore. Picked up a new mainboard and PSU locally from someone here in Sydney, wasn't sure if my butterfingers had killed both and was a big drive to pick them... -
Hello, this is my first post and im just a beginner, so be easy on me guy. thanks
i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.
i have no datasheet at all for the LED lights, all i have is its length.
long story short, testing the chandelier on the ground, and it works fine for 1 - 2 - 6 hours, no problem.
as soon as i fix the chandelier to the ceiling and bury the driver inside the hub,...
