    Message Tom66 he knows these sets inside and out. 8 Blue blink is normally caused by a 1.8v regulator on the AV board which has gone intermittent I will send you a link to a video that can help.

              Hello from Spain, I have the same TV with the same 8 blinking LED only when warm start, I have checked the IC Regulator that says in the video and when the tv is ok I have 3.3V in the input and 1.8V in the output. But when the tv is with the led blinking I have 0V in the input and the same in the output.

              Any ideas?

              Best regards.

                Yes, it now works after changing the regulator.

                  Same on my set. The regulator output 1.8V when set worked, 0.0V when faulty. Replaced the regulator and the set works perfectly 18 months later still going strong, fixed another one with the same fault as well.

                      I have fixed two of these high quality plasma sets, by changing the regulator.
                      In the first case the regulator would occasionally work, but after a minute or two, the 1.8V drops.

                        Just fixed one based on this great input. Did not have the correct part, but used a snall Intersil EVM, for ISL8016. Used a glue gun and three wires to connect, saved my friends day

                        If you have this issue, you can use pretty much anything that outputs 1.8V for 3V3 in

                        I measure 0.76Amps out of a 0.8Amp regulator ( Poor original design)
                        Now a 6Amp switcher is in place

                        Oh my GOD there is a lot of electronics in this beast, and I can hardly handle it myself....

                        It took longer to remove all the 78 ( !!) screws and get them back than to fix the issue.

                          Many dying 6-red blinks Sony FW-55BZ35F; looking for advice
                          by elbee
                          Hi,

                          The school where I'm working in AV is having ~25%> failure rate (12 and counting) on 4-5yr old Sony FW-55BZ35F's with a 6-blink LED code and I'm looking for troubleshooting advice/information in the case that there is a reasonable repair path. (e-cycling them is the alternative)

                          In searching the net for info it seems to indicate it may be the G* board power supply and being this forum has some deep technical roots in this area I'm coming here for the first time to inquire.

                          Is there anyone who may have a current Sony manual for this model or...

                          by Biruslapio
                          Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

                          Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

                          Panasonic TC-P55ST50 8 blinks then no blinks
                          by Andre Gilbert
                          Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing hereπŸ€”?
                          Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.

                          Pioneer PL-X9 motor speed control wobble
                          by Bushcat
                          I'm starting to re-cap a Pioneer PL-X9 turntable, specifically the motor control board, because although everything tests out OK according to the service manual, the speed wavers slightly despite the quartz lock light remaining on. So, I've decided to re-cap that board since it's the cheapest next step...

                          Pioneer's passive component naming convention is clear to me. For example, CSZA R22M 35 is tantalum, radial leads, 0.22uF, 20%, 35V.

                          BUT there are two capacitors on the board which have actual Pioneer part numbers: PCL-042. I can tell they are 0.1uF, 16V but don't...

                          Optiplex 3050 micro 2 blinks followed by 3 blinks issue
                          by Taurus12
                          Does anyone have an idea of what might be the issue with my 3050 micro? I have tried replacing new cmos battery but still the same

                          I am not sure if its the powersupply that I'm using is the issue since its the original powersupply. its a laptop powersupply with the same specifications with the 3050 micro so i guess it should be fine.

                          i also tried replacing the bios but with no avail, everytime i try another bios it gives a different blinking lights

                          Any recommendation on what I have to do next? Thanks in advance
