    LG Plasma 42pc3dv (z sustain board question)

    The tv has sound but no picture. When the picture origanally went out, I tested the pins (5v,Vs,Va) going to the y and z boards and the voltage was correct and the fuses are fine. After leaving the tv on for 10 minutes I touched the y-sus IPM and it was hot but the z-sus IPM was cold.
    I thought the z-sus was faulty, so I ordered a rebuilt one, installed it and I am still with no picture and a cold z-sus. Do you think I recieved a bad board? Could it be the control board? Or am I completely missing something? I have repaired many lcd's but never touched a plasma. These plasmas are a little more complex. I appreciate any help I can find and Thanks.

      I think I had a similar prob but I tore mine apart before I figured it out XP (sorry - wasn't worth the money in my situation) but I did post it here and someone did post an article on it to test the IPM and such.

                  Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                  by Tynan Dill
                  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.

                  by m1ch43lzm
                  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
                  Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                  LG 50PJ350 plasma blowing Y-Sustain board
                  by Keshenatech1
                  Hi, I was wondering if there's anyone here with experience on the LG50PJ350 plasma or similar models? When it came in, it had 7 shorted mosfet outputs on the Y-sustain board, Q02, 04,11, 22, 24, 26, and 28 were all dead shorted. I replaced them with the exact same type, checked their surrounding area for other open and shorted components and didn't see any further problems. But as soon as I hit the power button on the remote, I had a loud Pop! and Q22, 24, 26, and 28 are shorted out again. The other 3 seem to have survived. Someone on another forum had suggested the possibility of a shorted panel....

                  TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                  by howardc64
                  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!
                  I happened several times, in the search for help from the web, to consult this very interesting forum.
                  So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

                  Having said that I come to the gist of my post on the forum as the title suggests.
                  For my passion for technology I'm now collecting several...
