    Panasonic Plasma TX-P46VT20 blinks 10 Times

    Hi all folks.

    My old Plasma TV blinks 10 Times when i try to start it. Its now 2 weeks that i search like an old donkey on internet and i try everything.

    Nothing smell or looks like burned. I think its the A board, but i did not find more infos how search error on the A board. Replace it its not an option: I dont find part for this TV in my country and if i give it to a repair shop its to expensiv...

    What i have measured:

    Vsus and Vda are ok
    Pin1 of connector P7 : 5V ok
    Pin1 and 9 of connector P6: 16V in place of 15V but i find this is ok

    I executed all steps in the Troubleshoting Manual from Panasonic to exclude other boards: Disconnect SC20 to see how many blinks , disconnect A1 , disconnect P6/P7 and many more....with the result : Change A board.

    Im not happy with this answer, i like this TV and i wanna know why its dont work anymore, in the 90s we have repaired every electronic board...

    Have someone any idea ? I remember that in the first time the error whas shown i turn it off and on several times and hes restart normaly.

    Every help is appreciated, and sorry for my bad english, i never learned it.

    Thanks

    PS: The fans i have also cleaned with Qtips. Only the hairdryer i dont have tried already

          Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
          by Alicat
          Hello,

          Stopped by this site trying to fix my parents Panasonic Plasma TV.

          Model number is TH-50PZ85U

          Power comes on and the red power light stays on solid.

          Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

          I also hear a few clicks.

          I also think my parents said there was a thunderstorm and the TV failed after that.

          Section 6 in the service manual talks about power and no screen,...

          Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
          by Nairolf
          Hello,

          I have a Samsung DM32D display.
          When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

          Here’s what I have tried so far:
          1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
          2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
          3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

          From these tests, I suspect the problem might be on the mainboard. Could anyone...

          Panasonic Plasma ST50 TC-P55ST50 P55ST50 8 blinks
          by nick31
          Hello,
          My Oct 2012 panny plasma quit working yesterday.
          It was on when it happened. It let out a bit of burned plastic/circuit board smell. I was not able to find any burned parts though.
          Now it produces 8 blinks. According to the repair manual, that points to SS/SS2 board(s).
          I completed the steps in the guide: unplugged SS33, the TV turned on with a black screen, no blinking codes. Then I checked the continuity between pins 1 and 2 of the connectors SS52, SS54-SS57. The continuity is ok in all of them. Guide suggests to replace SS/SS2 boards so I placed an order...

          HP Victus 15-fb0104nw not turning on, charging led blinks 3 times
          by JarzabekPZ
          Hi,
          I'm working on a HP Victus that is not turning on. When power button pressed it only blinks 3 times with charging led. I have checked input mosfets and they are fine. Also all coils are fine too. Battery was empty but I charged it with my lab PSU and laptop started on batery but is not charging. When battery is disconected and only PSU connected it takes 0 current and not starting. What can be the reason?

          Panasonic P50VT20B Plasma 12 Blinks, Power Supply or A-Board?
          by Biruslapio
          Hello, I've had this TV for 3 years, 2 years ago it stopped working signaling 12 Blinks, SOUND_SOS according to the service manual.

          It has no VSUS or VDAT, and P15V has 1.0V instead, the same 15V goes to A board. F15V is ok and other main voltage rails.

          It seems the power supply is defective, since unplugging D20 ribbon cable that goes from D-board to SC-board makes the behavior change, the TV stays on, there's no image nor VSUS, but 15V reads 2.4V, high enough to not trip the SOS 12 blinks, so it stays on, fans do not spin but I left it 2 hours, green led lit up...
