    I've had a similar experience. After ruining a Y-Sus, I now always power down plasma TVs before changing connections. Also, the Y-Sus boards sometimes hold charges for a while after the main power is disconnected. So, I monitor voltages at the connectors and discharge caps on the Y-Sus before proceeding.

      I suspect there is likely a short on a board other than the power supply, but i have no specifics other than what I show in some of my other videos which can be found at www.tvrepairinfo.com/

    I wish you were in my area. We have no one who will repair plasma TVs in the Dallas metroplex. I have a Panasonic TC-P50UT-50 plasma that has no power, no stand by, nothing. I had a cable box, which was connected via HDMI, short out and after that my Pani has no power. Would my main culprit possibly be a blown fuse on my power supply? How can I check to see what's dead? Any help would be GREATLY appreciated. I miss my TV.

    Do you have any experience with an LG model 50PJ350 Plasma? Got one in with 7 different mosfet transistors on the Y-Sustain board dead shorted. Replaced all 7, powered it up, and, well I should have saved it for the 4th of July lol. New parts went off like a string of firecrackers. So I'm wondering if something in the panel or on another board can blow up the Y-Sustain board, or if I most likely missed a bad component? No more obvious shorts but there are several control IC's that can't be checked with a simple ohm meter. Bottom line, would it be worth $75 plus shipping to try a whole different Y-Sus board, or is it likely something in the TV would blow it up too?

    A friend of mine has a 42" Sanyo Plasma TV. He has his XBOX plugged into an HDMI port. Every once in a while the TV Will turn off and the Xbox will reboot and then the tv will turn back on and put out this really high pitched squeal. It doesn't do it all the time, it does it most on the xbox input, but will occasionally do the same thing on the DVD HDMI input as well. We have never noticed it doing it on the Composite input.
    Just wondering if you've ever heard of this?

If I lower the brightness is stays cooler and it lasts much longer before doing it. Do you think it's the tactile buttons board that may be faulty?

    Help/Ideas?
    Model: Sony KDE-42XS955
    Type: Plasma
    Size: 42 inch
    Manufactured: 2005
    Retail: $4,995
    I bought my Sony KDE-42XS955 from B&H Audio Video in Manhattan for $4,450 in July of 2005. It was the absolute finest TV on the market at that time. It never gave me any problems during its 11-year-long life. It finally died in March of 2016. It was still producing a perfect picture up until it simply refused to power on. When it would power on, only audio was working. The video went from perfect to nothing. There was never and fading of its quality over time. This leads me to suspect there's some internal power supply issue, or something that has nothing to do with the TV's ability to produce an image. Because again, the image was always perfect up until it died.
    I wonder if this TV can be fixed? It was the greatest TV I'd ever owned, and I've had many since this one. Today's average market range TVs still aren't as good as this set. This is why buying the finest TV you can pays off. You future-proof yourself for at least a while. Again, except for the highest-end sets, my 2005 Sony plasma was better quality than 95% of the TVs made in 2018.
    Any ideas? Thank you for your time.

    Holy Cow. i am not even a TV tech, just a all around fix it man really, i do admit to having over 21 years in the car audio field and I can and do repairs on old school car audio that is WORTH it, and I also have been building custom computer towers and lap tops for 19 years. but I have never, not even as a rookie kid, thought that it would be OK to disconnect or re connect any wire, connection, ribbon or anything that requires power. YIKES! lol
    I guess it's a good video but WOW. Oh yeah, with these kinds of things that have capacitors and have only recently been disconnected from power, sometimes the stored power in the caps can cause this same problem. best not to mess with it till you have the power dissipated. for instance, people have been sent to the hospital from reaching into the back of a unplugged microwave oven. thats a load of power. it doesn't take much to fry a ribbon cable.

    hi Grants,
    finally my tv : philips 42pfl7422/98‏ PSU gave up with blown fuse.
    further check result :
    1. STW18NK80Z(Mosfet Q901) fail - Replace with STW25NK120 (higher Amp & voltage)
    2. TEA1507P (IC904) fail - Replace with TEA1507P
    3. RGP10D ( Diode D912 FRecover 1.0A) - Replace with F.Recovery 1.5A Diode
    4. Main Fuse T5.0A
    After replacing mention component, TV manage to power up & functioning as normal but the heatsink (Q901 mosfet) is very hot to touch and finally after 30min, PSU give up and blow up those newly replaced component.
    any advice what did i go wrong??
    is it a miss out of bad cap that draw too much amperage from the Mosfet transistor or the inverter board is drawing too much power??
    hope you could enlighten me.
    thanks in advance.

    Hi,
    Thank you so much for sharing your knowledge. Your videos are so informative and easy to understand.
    Recently I acquired an old Samsung ps42c7s with a bad y-sustain-buffer board - 2 of the IC's are cooked. On close inspection I also noticed that one of the buffer board ribbon cables has a slight tear across it through several of the thin "etched wires". I believe these cables are fused to the panel & cannot be replaced, but is there any way that such a tear can be repaired?. Thanks.

    Yes, but what damage did re-seating the connectors do to the board? Is it because a couple of pins shorted, or because voltages were fed back on the wrong pins? Or what? Aren't you curious as to what mechanism caused the failure and what it did? I am.

    • @GrantsPassTVRepair
      @GrantsPassTVRepair  3 года назад

      Yes it did make me wonder about the cause. I can guess and say it may have been a DC arc from one of the coils being abruptly disconnected while the power was applied, , or perhaps a load imbalance across an IC due to not having a load on the output of my power supply.

It;s possible you have burn in issues, sometimes if some one in your house likes to watch sports or a programs with Bright banners and tickers running on the screen, football or whatever, things that stay in the same place on the screen and run for a long time, when you shut it off you can still see where those things are. also when the next user comes along to watch something else BAM they can see the things that were on the previous viewers screen! the problems will get lighter and lighter as you watch the NEW thing and then should go away completely until that other viewer does it to you again. video games will do this as well.
