Re: Panasonic #Th42ph9uk plasma Stby light x11times.
11 blinks FAN error, check all fans are clean and running, check for good supply to fans, etc...
50" manual is likely to be good enough. ET is down right now, at least for me...Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Then you have found the fault. Replace the fan to fix it. You can probably use a computer fan as long as it is 12V DC (most are) and quiet.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
The faulty fan has 3 wires,red,black and white.The white wire is connected
to an area labled FAN SOS in the SM.I went to a computer store yesterday
and I saw a 12v fan which has 3 wires red,black and yellow.I have seen fans
with 2 wires previously, and I think that the fan should be replaced with one which also has 3 wires.Comment

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
Buy the fan in the computer store and connect it as follows: Red to red, black to black, yellow to white. It should work. The 3rd wire is a RPM sense signal - it tells the speed of the fan to the device it's connected to. Its colors may vary. Vcc and ground are almost always red and black respectively, i say it's a 90% chance it'll work.A working TV? How boring!Originally posted by PeteS in CAComment

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
The only concern I'd have is I had an NEC plasma where the fan signal was ON or OFF, and not a PWM signal, with LOW indicating the fan to be running, some kind of rotary speed sensing switch. The Panasonic MAY be the same...Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
How sure are you the fan is the same type?
Very surprising if the fan was stopped, and now spinning, but still detecting fault.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
I have a Panasonic Plasma here similar problem, but LED blinks 12x (actually is 11x apparently) which suggests a tuner issue, likely DG board. Very complex TV with many boards, there's another thread on here about it.. Not sure how close your model is to mine.Last edited by kevinm34232; 09-22-2012, 11:55 AM.Comment

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
It will be a slower fan then, so likely the TV is detecting a fault with it. You would need to get one for a 42" set.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
or.. do a bypass by connecting the yellow wire from one of the running fans to that other input ? just an idea.. giving the rpm sense or whatever signal it's sending to fool the unit..Comment

Re: Panasonic #Th42ph9uk plasma Stby light x11times.
Could try that as a test, though you would want to fix it properly before it is assembled.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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,...10-30-2024, 10:09 AM -
Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.
For my passion for technology I'm now collecting several... -
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...01-06-2025, 06:02 AM -
My parents' Panasonic P42S30 died recently, and they asked me to have a look at it. I was able to identify the SN-board as the culprit, as it was shorted. After removing Q401, Q402, Q421 and Q422 the short was gone, so I replaced these components and that got the TV working again. However, when testing the tv a bit, I noticed quite bad pinkish sparkles on some colors. For instance the greyish bar on this forum seems to trigger it quite badly. I made a fullscreen test picture with only that color, with the below result.
There is about a 5cm high region at the top without any sparkles,...
