Hey everyone, if anyone has an upper buffer for a Hitachi p50h401, part number jp6079 please PM me with the price. Just had mine stolen by a shady eBay repair person. Thank you.

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

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
I just acquired this portable aircon, history unknown. Its behaviour is quite strange:
- When turned on and placed into cooling mode, the upper fan (cold air out) just spins slowly. The compressor and lower fan do not run.
- If the device is then placed into heating mode and then back into cooling mode, the lower fan and compressor kick in and start cooling, but the upper fan still only spins slowly.
- If the device is placed into fan-only mode, the upper fan does not respond to low/medium/high speed toggles - just keeps running slowly.
- Display and buttons all behave normally aside from the

Hi all,
I'm interested in understanding how a buffer board chip is working. I know there's about 90 outputs per chip to the plasma panel, but I'm more interested to know about the input pins. I guess that some of them are address pins, but I want to know more.
So far I've found nothing at all. I haven't found any datasheet about the various buffer chips, and I haven't found any schematic for the buffer board using them (Y Buffer Board in Samsung's terminology).
Any information will make me happy. It can be from any buffer chip or plasma TV manufacturer.... -
Hitachi 32HAE2351 Vestel 17MB171 - Rotate Image
Mainboard: VESTEL 17MB171 Chassis: VES315WNGB - 2D - N52
The TV was stuck on the logo and I couldn't access the update menu.
I couldn't find the firmware for the Hitachi 32HAE2351 and updated it with the Toshiba 32WA2063DG - Vestel 17MB171 firmware.
The image result was good, but the image is inverted.
The image rotation/mirror function doesn't exist in the Menu Server. I can't correct the image.
Do you have the firmware for the Hitachi 32HAE2351 - Vestel 17MB171 motherboard or a solution to rotate the image in...
