    Cracked plasma screen can damage the buffer board

    I was about to sell this part I pulled from a 42" Samsung with a cracked screen. The cracked screen shorted electrodes damaged the Y-buffer. So sometimes the Y-buffer can be damaged when the screen gets cracked.

    Also an example of why a fast continuity range on a multimeter is a must-have!

    So it's possible a cracked screen can cause a buffer to fail which on some plasmas could cause y sus board to die , so we could have a sort of knock on effect.

      Re: Cracked plasma screen can damage the buffer board

      I have not encountered a buffer killing a Y-sustain. I have encountered a Y-sustain killing a buffer though. The buffer ICs have a fairly high resistance which will be relatively harmless to the Y-sustain should something fail in the IC; only if all of the ICs were failed would I consider it possible.

          52" will be an LCD. No one makes a 52" plasma. I'd consider a 52" LCD, but I'd really prefer a plasma.

          I'll wait for the summer holidays before I consider picking up one for the dorm - not really enough space here to store it...

            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....

            Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
            by Ryan.man
            Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

            My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

            This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

            Schematic or datasheet for Plasma TV buffer chip
            by Yanleb
            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....

            M1 A2338 screen and touchbar issues after cleaning up liquid damage
            by jkruns
            Hello everyone,

            This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

            My patient is an A2338 Macbook Pro M1 (late 2020).

            It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

            Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
            by Alicat
            Hello,

            Stopped by this site trying to fix my parents Panasonic Plasma TV.

            Model number is TH-50PZ85U

            Power comes on and the red power light stays on solid.

            Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

            I also hear a few clicks.

            I also think my parents said there was a thunderstorm and the TV failed after that.

            Section 6 in the service manual talks about power and no screen,...
