    Re: LG 50PS60 UA Plasma

    I think your Z-sustain may be bad. If you run the set for some time, then turn it off, see if the heatsinks on the Z-sustain feel noticeably cooler than the Y-sustain. I am confused though - I thought you had the vertical lines issue which was the Y-sus/buffers. And then the Z-sustain goes bad. It's very odd. Definitely not an easy first project!

      This first project makes me wanna read books instead of melt my brain with TV

      At first, it had that bluish screen that was all pix-elated. One afternoon, I turned the set on to get the readings you suggested, and I heard a "pop" and I lost the picture totally. That's when the Y-Sus board started "surging" and the readings were fluctuating every three seconds. So, I unplugged the Y-Buffer boards, and the Y-SUS board stabilized. So, I ordered the Y-Buffer boards, upper and lower, and my picture came back, but I still have that weird pix-elated picture. I understand why you're confused about this situation.

      I'm going to turn it on while I do homework, that should give it enough time to warm up.

        Well, as luck would have it, my television has been on since I checked the Z-bias earlier. Both the Y-Sus and the Z-Sus heat sinks are hot, but I don't think either one is hotter than the other.

          Can you supply a clear picture of your Z-sustain board?

              Here's a video as well. That clicking noise is my dog walking around, not the television popping!

              I hope this helps! Whatever else you need, just let me know!

                I'm planning to order the Z-Sustain today. Keep your fingers crossed.

                  Goood afternoon!

                  It's been a few months since I updated this thread, school has had me busy this past semester.

                  I replaced the Z-Sustain board in this display, and the fault didn't go away. After school was out, I ordered a Y-Sustain board and installed it.

                  I'm happy to report the television has a perfect display. The fault is gone.

                  Is there any tuning I should do? I'm afraid to attempt anything without consulting with you first!

                  Have an amazing day!

                    Victrola multi-player - No audio
                    by kokopelli75
                    Hello!

                    My mother has a Victrola Navigator player that stopped functioning after a storm. I checked out what I could - all player functions appear to work, but there is no audio output in either the speakers or the headphone jack. I suspect (with my limited knowledge) that the amplifier part of the device is toast. Photo of the suspected board is attached. There's separate boards for front display, record player, etc. This board has a section for power regulation and a section for amp. There's a UTC7266 7+7W dual bridge amplifier IC and a CSC2314F sound processor IC on the board. Visually,...

                    LG BH6420P Home theather blue ray player repair
                    by unimatrix93
                    Hello everyone, I'm trying to troubleshoot this LG hometheater player.

                    The customer forced her USB drive reversed into it's USB socket and since then the player won't work properly, only shows "Please wait" error forever on it's display.

                    Now I started diagnosing the USB socket and the mainboard where it's connected.

                    I found 20ohm resistance to ground on the 5V line of the USB.

                    5V is missing and I found the buck converter of the USB line, TPS65252 IC.
                    After measuring the pins I realized that both VIN and 3V3 is correctly present...

                    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.
