    philips 42pf9946 plasma display problem

    hello ladies and gentlemen.

    this is my second plasma repair so i want to give my best.
    i have no rich experience in plasmas so any help is praised.

    this is a Philips 42PF9946. the problem is shown in the pictures. the pdp seems to be Samsung S42SD-YD05, (from the back label).

    i havent opened the cover yet, but i'd like to know any early opinions.

    thanks in advance.

      Very likely a buffer fault.

          thank you tom. i did some more searches and turned out this tv is famous for the notorious buffers. but the real problem is with the owner who refuses to pay any real money for repairing it. it sounds stupid but he claims to be some kind of technician and is convinced on "resoldering the tuner pins". he states it is an antenna connector problem. c'mon! cant troubleshoot the problem with this pressure
          i think i am forced to give up.
          anyway i'll make him an offer as he was totally broke, and revive this thread later.
          thank you for your attention!

                  My guess is (other than buffers) maybe CTRL board...

                  Cheers!

                          Problem with LG Plasma 60PM6700 - Random power downs
                          by theone111
                          I have an LG Plasma TV 60PM6700 for the past ~12 years.

                          In the last ~3-4 months I have been having some issues.
                          1. Problem: It started with random picture disappearing (sound still worked).
                            Frequency: Happened about once a week.
                            Solution: Had to turn off TV wait a few seconds before turning it on again.
                          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                            Frequency: Happened about once a week.
                            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                          3. Problem: TV shuts down

                          Philips HTS8000 home cinema noise problem
                          by courtcircuit
                          Hello

                          I have since a long time a Philips HTS8010S/01 which has been old but was doing the job.

                          Since a few days, it starts by making a weird "static" nois when switches on for a few seconds to a minute and then works like a charm.
                          Noise loudly outputs from the 3 channels, even if no signal is sent by the controler.DVD to the subwoofer/amp unit.

                          I was thinking of a soldering that was starting to be damaged and that was only doing the job after a few seconds of heating, most probbaly on the power board
                          Removed each of tyhe boards

                          Hello guys,
                          My Plasma Philips 37inch chassis FTL2.1 does no picture ,and goes into protection mode after 30 seconds (red led blinks at 3Hz).


                          Can someone has any symptom like this ?

                          Philips 58PUS8545 t-con problem or something else ?
                          by atkallu
                          Hello
                          I have a Philips 58PUS8545 which have a vertical moving lines on screen and it is flashing white vertical lines like a every 3-4 seconds.
                          See the attached image.

                          I removed left side flex-cable from the t-con and then there was half screen sharp and correct image and other half was white.
                          But when I removed the right side flex-cable then half of the screen was white but other half was white and above the white there was vertical lines on half of the screen.

                          T-con two flex-cables have been changed to cross but nothing changed, so it is not due those...
