    LG 60PC1D problems

    Hi all. First of all, thank you for the great support you have all already provided me. Via a thread here, which I found via google, I have been able to do some troubleshooting on this TV, but cannot get it functional again.

    So, this TV is my dad's who lives 900 miles away. about 3 weeks ago he called me and told me the TV popped and the picture went out while my mom was watching. I told him to get the TV off the wall, take the back off, and look for any bad capacitors. He found one and I hoped for $5 and some solder we'd be able to get it fixed.

    He got a new capacitor and had it soldered in by a friend with better vision than his, and the TV still didn't work. Since I wasn't there to look at it myself, he decided to take it to a TV repair shop near him. They told him they could fix it for $150, so he said ok. The next day they called and said there was more damage, and it would be $450 to fix. He decided he'd rather just buy a new TV, so he said no to that and asked for the TV back. They of course got defensive, and told them they already had so much work into the TV that they had to charge him $60 for the labor. He paid it, took the TV home, and waited for me to come down for Christmas.

    They had told him he needed a new power supply board and something else, but were not pleased when he denied further repairs, so they wouldn't be specific. I assumed a new power supply was needed, and ordered one off eBay for $85 and had it there when I got there. When I got there, I looked at the old board and it looked like they had repaired a solder joint and cleaned up the solder job my dad's friend did on the capacitors. And though it was putting out the same voltages as the new board, I went ahead and put the "new" board in. I tested it's Va and Vs voltages, they were a little low so I adjusted them to what the sticker inside the panel said was correct. I fired up the TV and we had sound but still no picture. Using this site, I figured the next culprit was probably the Y-SUS board. I checked the fuses and sure enough found a popped fuse. I could not find the dang fuse locally though, and rather than wait several days for one to be shipped only to have it pop again, I just got another Y-SUS board on eBay for $65. It did not arrive prior to me having to go home though, so my dad had to put the board on. I gave him careful intructions for doing so, and he called last night to say that he got it in, and the TV is showing something now, but it is not a correct picture. The description he provided me wasn't clear, but I think he was saying there were lines and the words on the screen were blurry.

    Today sometime he is going to call me and I am going to have him hook up a DVD player to it so I can tell if it is processing any input source at all. I suspect he'll get the DVD video but garbled. But I will know for sure later.

    Either way, from what I'm reading, I'm now leaning towards the Z-SUS also being bad. Is it likely that the power supply, Y-SUS, and Z-SUS all went bad? The Z-SUS is the most expensive component to buy it looks like, so I hate to buy this thing and not get a picture on the TV when we are done. In other words, I'd like to not just keep throwing parts at this thing. How can I be sure of my next step?

    Thank you all.

    Tbh its the worst thing Ive ever read. We cant guess the issue, can you please upload pictures of the fault along with a list of the tested sustain voltages in the Tv please then we will be able to help cheers Plasma too many things to go wrong guessing is just not an option.

      Re: LG 60PC1D problems

      Thanks, I certainly understand.

      In short, the TV turns on, stays on, and plays audio from an input source fine. But the screen wouldn't light up. The PDP doesn't have any damage.

      I checked the Va and Vs voltages on the power supply board. Va read 59.8 volts (sticker calls for 60) and Vs was 192.9 volts (sticker says 193). There were also 5 volt wires that were right at 4.9 volts. Do I need to be checking these voltages on the sustain boards also?

      I will have to get a photo of what the screen is doing later when I talk to my father again.

          I am unsure how to check those but will have to get my dad to do it. So I'll figure that out and then get him on the phone. In the meantime though, here's a photo of what the screen is looking like. We also found out one of the connectors on the "new" Y-SUS board was partially broken off. I'm not sure what the wires connected there are for, it is a small 4 wire connector and the wires head off underneath a small cpu style fan towards the bottom of the display.

            He shouldn't of paid that shop a penny, looks like they could have bodged it on purpose. Also thats quite bad Ive not seen anything like that before on a Plasma. I would be pushing for a control board fault but looks like the panel might have been sabotaged by the shop, the connectors at the top and bottom of the panel are they seated properly ? Also its very dim looks like Ysus could be faulty or Zsus. Could also be a buffer fwult, but I need a voltage list please.

              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.

              Assuming...

              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...

              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....

              LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
              by Hakuu
              Hi There,

              This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

              After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

              More Details

              TV Model - LG OLED77G1PUA

              Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

              problems with LG OLED 55EC930V, t-con board LC550LUD-LGP1
              by randaz81
              I have an LG OLED 55EC930V.
              The problem started a couple of days ago: tv working, but no video, only audio.

              I opened the tv and I checked the parts. The mainboard has the red led on, which means that it working correctly. The power board supplies 24V correctly.

              I focused my attention on the t-con board, LC550LUD-LGP1, I disconnected it to observe it carefully, no signs of damage. Then I mounted it again and I reconnected to the tv.

              After this, the tv started to show a different behavior: it turns on and then, after few seconds, it turns off....
