    Re: Panasonics Are Out To Get Me TH-42PZ85U 10 Blinks

    Ahhhhh... I see the whole thing now...

    Looks like a healthy project..

    But my concern is this. I froze the whole board, cap, chip and all.. If that didn't temp fix the issue I am wondering if replacing the chip is going to repair the issue..

      That makes sense.. The ICs are too far gone for freezing to help..

        maybe tom has some more input some voltage checks maybe? im sure ive read about a thermal fuse in a transformer not sure what model panasonic it was refering to though but im sure tom fixed one with the issue.

          I don't know this helps but I repaired 5 of these tvs in the same problem and I never had a bad IC on any of 'em yet. it never would hurt to try using some heat on that suspect cap. A few of them worked with heat in a few of them worked being frozen so it's kind of a crap shoot but if you have the means I would definitely replace the caps for good measure anyway

          Did I leave the soldering iron on?

            I've read removing those small caps can also get these running although 10 blink at plug in may not be these modules. i've had the 2 blink at power on and was just the cap on one of those modules.

              Board replacement is $150.. Spendy, but if the customer is willing to spring for it...

              Another option is the repair kit from SJ....

              Although I tend to shy away from repair kits, I had pretty good luck with that option the last time..

                Yea, might try a reflow as a last resort..

                  I'll give that a shot when I get to the shop...

                    What you should get is the standard click click from the power supply at plug in. Then no led. When you press the power button you should get an additional click click then a solid red led for a few seconds followed by either a 10 or a 2 blink code repeatedly. This would indicate a failed module. Also remember on these models they have been known to be finicky with the front HDMI port with a computer or a game console shutting down the set with a 10 blink code. This was recoverable by holding the power button for 10 seconds.
                    Did I leave the soldering iron on?

                      What I am getting in this case is, at plug-in, a double click, a sec or two pause and then a single fainter click and then the 10-blinks on the power LED.

                        actually, ignore my remark. just had a refresh of the norcal video and the 10 blink at plug in is clearly mentioned as part of the mc201,301 modules.

                          Unless you've discovered something totally new, the likely standard fix has been and will continue to be to replace the IC's and the caps. The repair kit is only about 15 bucks. If it doesn't work, I'd try something different.

                              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.

                              Sony KDL-40Z4500 LCD with stripes and 9 blinks (possible BGC board or harness problem
                              by huj3r
                              Hi there!

                              I have a Sony Bravia KDL-40Z4500 which shows a colored vertical stripes pattern when turning on, with a central black shadow that slowly dissipates within the first 10 seconds.

                              Photo of the situation after the black shadow dissipates:

                              After this behavior the red LED will blink 9 times, then pause for a bit, and blink again 9 times, in a loop.

                              I checked the manual (available here) and this corresponds to "HFR error", quoting from the manual:

                              Hi There,

                              This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                              After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                              by mmischni
                              Greetings friends,

                              I have a Panasonic TH-42PX75U manufactured in 2007. It has been trouble-free until recently. One evening I turned it on and it then powered back off and gave 7 blinks.

                              First a question about the blinks. Everyone only speaks of a single number of blinks. I noticed on my TV, it blinks one fewer times for the first group of blinks, then blinks the full number repeatedly. So for my first code in question, the TV switches off, blinks 6, then blinks 7 repeatedly. When I disconnected the SC board, the TV switches off, blinks 7, then blinks 8 repeatedly....
