    Re: LG 60PV450 Sound No Picture

    Top buffer ok?

    I have an extra set of buffers tested and working when I was repairing mine. But they are for the PDP60R30000 (first revision) But I am running all PDP60R30110 Y/X and buffers on my PDP60R30000 and its been going strong now for a month or so.

    I would assume they are interchangeable between Ysus boards too.

      Went through the panel with some magnifying glasses and all looked OK. TV was on, wife heard a small pop sound and smelled small burning so I am assuming that was the bottom buffer. I knew I should have ordered from ShopJimmy this is the third board I have gotten from eBay that was bad (for other sets). I am buying the exact same TV tomorrow for $60 with a no power issue, at least I have some good experience now. Thanks for your help!

        Nice!

        I have two of these as well. Going to be wall mounting them both side by side in my man cave!

        I have 2 sets of working buffers and a Ysus as well.

          I am happy to get a set from you if you want to sell them! Let me know a price and your Paypal email address (if you use Paypal), and I will get you paid.

            I will be home later this evening, I think they are already boxed up ready to ship too.

            I will be in touch later this evening.

              This does seem to be a particularly troublesome model from LG. Wonder if they wanted to get it out quick for black friday or something like that.

                The 450 is the Costco version, I think the 400 was the Walmart/retail Black Friday set of I remember correctly.

                They share the same internals thought as well as several other LG 60" plasma displays.

                      That sounds great, I will wait until I get the other 60" tomorrow as I may want to buy the YSUS board too if you are thinking of selling that. If so come up with a package price for me!

                          Hello Shinju! I received the other 60" today. After taking it apart checked some of the basics, buffers seem ok. My Vs voltage was dead on, but the Va voltage was about 52.6 and supposed to be 55. I tried the adjustment but would not adjust past 52.8, would go down but not up. Should I be checking mosfets, caps and resistors on the power board?

                            Was the Ysus connected for your test or disconnected?

                              No, but I got it. The Zsus board was bringing down the voltage, after it was disconnected voltage jumped up on power supply to 55.1. Helps having two of the exact TV's here, swapped out the Zsus board with other set and plays perfectly. Going to let it run for a bit to make sure no other issues.

                                  Would you happen to have a Zsus board also? Pretty hard to find, if so get me a price for that and those buffer boards please.

                                    Only extra X boards I have are shot and will need to be rebuilt.

                                    Sorry!

                                        word, how about 100+ ship for the Ysus and matching buffers? I think that's a pretty competitive price

                                        I think I can get em shipped for 15.00, anything more then that I will cover it. I like to over pack to protect.

                                        These boards have been tested in the panel and found working, I ran the test patterns and they all came up crystal clear. I only took them out so that I could match the parts from 30110 all around, all though I know you can run the 30000 X and Y boards mis matched with the 30110 boards as I found out after words. I also was using the test points on the Ysus wrong hince what I thought was low voltage was acctually correct voltage when I put the + and - probes on the + and - V test pads!

                                        My repaired LG 60PV450 Frankenstein is still up and running perfectly fine.

                                            by TR103
                                            Hi, I have a Samsung UE50TU with:
                                            - sound and backlight, but no picture
                                            - when it arrived, it had a picture for a few seconds
                                            - it keeps rebooting
                                            - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                                            - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                                            - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                                            - without cable between mainboard and lcd panel and with a jumpered...

                                            Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                                            by Mgiffune
                                            I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                            I ordered a supposedly ‘new' Tcon board this time, and
                                            ...

                                            Hello everyone,
                                            Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
                                            The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
                                            He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
                                            I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
                                            Anyway I still fully expect that there has been something seriously damaged...

                                            Hi all

                                            I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



                                            Symptom:
                                            No picture no sound.
                                            When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
                                            No sound at all.



                                            What I tried:
                                            1. I tried unplugging the left or right ribbon...

                                            so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

                                            i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
