    Panasonic 37PX8EA 1 Blink error

    Hey People ,

    Im new to this forum so first of all hi!
    English is not my first language so forgive me for some grammar mistakes.


    I got a Panasonic 37PX8EA which has the 1 blink error message , been reading a lot of information on the internet/this forum and if im correct the problem is the "STV 5v Sense DG board" right? Where on the DG Board can i find the component that is causing the problem?

    I also read that it can be a EEPROM problem? Where is the EEPROM located on the DG board?
    I already tested the tv with a spare power supply but it does exactly the same with both power supply's. So it turns on , i hear the relay click and after a few seconds it clicks again and the led goes from green to red.

    Its easy to throw away the DG board and buy a second hand board from ebay but i want to learn more about these boards.

    More information about this plasma to give you guys as much information as i can! ( im pretty new to this )

    1) The TV has a total of 4 boards. ( Power supply , Zsus , Ysus , DG board. )
    2) DG board model nr = TNPH0711 / TXN/A1BVUD

    I have a different panasonic tv as a spare but it has a different DG board. ( 1 big board with a small board behind it ). ( model TNPA4310 )

    If anyone could help me out or point me in the right direction would be greatly appreciated. thx!!

    I hope that i named the boards correctly. With DG board i mean the board that has all those IC's. ( IC9001 for example ).

          Try unplugging Y and z sus. boards then turn on set. This could eliminate 1/2 your problem,

            Thanks for the replies guys!

            Here are some pictures of the boards.

            I already tried to remove Y/Z sus boards but the problem stays the same! The blinks never change to 5/6/7/8/9/10 etc.

              I did ask you to post the picture on site so they remain for reference.

              They are not clear enough to see the detail - you will need to google the part numbers and check out which are eeprom.
              I believe ESMT make bios chips so may well be those.

                Ok im sorry i didnt know how.... :/

                Ok thx , i will try to find out wich 1 is the EEPROM. Do you think that chip is the problem?

                When i remove just the Y-sus board the system turns on and gives 1 blink code
                When i remove 1 cable from the Z-sus board the system turns on and gives 1 blink code
                When i remove the Z-sus completely the system does NOT turn on.
                When i remove just the mainboard the system does not turn on.

                The blinks never change in all combinations.

                  eeprom chips are also made by Atmel if you can find any of those?

                    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                    by Tynan Dill
                    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                    Upon bringing it home and plugging it up, it showed a standby light.

                    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                    The screen seems to blackout and stay black, but with a flashlight I can see the display.

                    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                    Assuming...

                    Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                    Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                    Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
                    by sam_sam_sam
                    I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                    This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                    Panasonic TC-P54VT25 No image. A or D board?
                    by canadaboy25
                    I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                    The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                    I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
