    Any thoughts what could go wrong with my Plasma TV?

    Hi All,

    I posted a thread in June regarding the problem I had with my plasma TV, and have some new symptom need some advise. Basically, it went wrong last June with the first three pictures. Then I replaced Y-drive boards (both up and bottom), Y-sus and Z-sus (purchased used parts from ebay). Now the symtom is kind of different (pictures 4 to 6). Any ideas what else could go wrong or the parts I got from ebay is defective? Thanks!

    Hello,
    I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
    Opened TV cover & observed foll
    a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
    b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
    c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
    How to confirm Y -Buffer board...

    Panasonic plasma TX-P42ST50 - 6 blinks
    by jm1234
    Hi,
    anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
    It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
    I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
    I checked that board for any obvious faults...

    Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
    by KYBOSH
    Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
    No picture but you hear the TV static (white noise) playing loud and clear.
    The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
    But it seems they didn't get too far and just left it.

    When I first took a look I was amazed at how pristine the inside looked.
    Its as if the TV had been in a time capsule.
    Caps looked like they were just pulled off the self.
    Copper coils had no sign of corrosion on...

    Dell Latitude 7420 BIOS Unlock Gone Wrong
    by Jeff'sTech
    Hello everyone.

    I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make...
