    47pfl6008 blinking red

    Hello,

    i have 47pfl6008, at latest half a year sometimes TV turns OFF suddenly. Then you need to turn ON again. Yesterday when i want to turn it ON, red light blink two times than pause, and again two times in a sequence. I plug it out and then back in. Now the red light is off and TV wont turn on, only a short red blink for 0,1sec.

    What to check, seems everything oken on MB.

    Which is the Country S??
    Very common problem of the model, bad BGA solderings on the main chip (Fusion).. Reballing is a solution, reflow is a looser solution..

        What you don't understand that is not the heat the problem, is bad solder, soon or later you will face against the same problem, if i have time i want to experiment on mine, these days of weekend, i have two of those sets sleeping since years.. i want to warn you that years ago i tried reflow too but a previously half working set became totally dead, no components flawn..

                by Cookybaby
                Hello Everyone, this is my first post and I am excited to be a part of such a great community. I've been reading these forums for awhile and there really is some good friendly people here. No bashing and being rude like 90% of other forums Ive been to. Lets get to the good stuff.

                I have two years of college in Electronics Engineering Technology. Ive been tinkering with electronics sine about 1990. I know enough just to be dangerous, so be gentle.

                Panasonic ZT60 plasma tv with strange behavior and 8 blink code
                by cloo
                I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
                It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


                So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
                After doing a factory reset this problem was gone and the picture was back to...

                Each GPU reballing produces different MATS results, looking for root cause ?
                by DynaxSC
                Hi,

                I have an Nvidia card which makes me wondering, what is the root cause for Mats errors. The story is as follows:

                1. When I received the card Mats showed one memory with errors.

                2. Replaced the memory chip, but no change, still same error, so memory chip is ruled out.

                3. Made a carefull reballing of the GPU, MATS showed 3 memories with errors, the one before, and 2 other new chips.

                4. Made a second reballing of the GPU and Mats shows again only one memory chip with errors, the same on as in the beginning.

                5. Made...

                Un50cu7000 2 blink oddity *partially solved
                by EazyBone
                I write this to maybe help another with this TV.

                So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.

                The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.

                QN750Q8FNBFXZA Service Error Codes Needed - Error code 1-3-1-2 ? Dead set, only blinking standby light in repeating sequence
                by mecha1166
                I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks!
