    Marantz Plasma issue and OEM?

    This one Tommy can probably answer?
    Client wi9th a Marantz PD, think PD4220V (NEC ?) I think NEC, Marantz, Runco, maybe Philips all used the chassis?

    Unit powers up with video for 1 minute, changes to a blue screen with video (all blue shades), then goes dark. Continues to recycle that way every few minutes.

    Any ideas of OEM and part?

    Thanks as always!

      Marantz is (was) NEC's high-end brand if that helps.

          You think that is a main video board issue? Or am I looking Sustain, inverter's X, Y etc? Obviously not a power supply or panel

                  I fixed a 50" NEC with a similar problem (turning off after 30 seconds)
                  Cause was a bad audio amplifier board, triggering a fault code.
                  Other possibilities are stuck cooling fans.

                      Samsung Plasma TV Power Supply Issue
                      by lp20th
                      I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the...

                      Issue with Plasma Philips 37inch chassis FTL2.1
                      by celiabrown
                      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 ?

                      Thanks​

                      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
                      by rounin
                      Hi everyone,

                      I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

                      🛠 Original Issue
                      The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
                      Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                      I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

                      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

                      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                      by ugamazing
                      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                      Set-top box HDMI output >AVR 3 HDMI input/one HDMI output>HDTV HDMI port
                      If I bypassed AVR then HDTV screen color be good.

                      I take out HDMI board from AVR and check services manual the schematic shown the HDMI signals path:
                      3 HDMI input port > SIL9185 chip(HDMI switch) > SIL9033 chip(HDMI receiver) > SIL9030 chip(HDMI transmitter) > HDMI output port

                      I replaced all...
