Re: panasonic TX-P42X20B flashing red
My boards from a 37" and I've been on that bit and mine said 42NG and tried selecting it but just goes back to 37"display on switching on again. Dnt know if there was anything else needing done for it to stay that way. Been through all ye service manual and says to check other things if NG displayed. Hope to get data from board if someone could copy it to SD card and post it on here so i can try it to fix mine.Leave a comment:

Re: panasonic TX-P42X20B flashing red
I don't know if this will work but have you gone into service menu and drilled down to Panel type in the option field. On my 2009 series it shows 42HD, OK. Toggle with Vol - , shows a second option 50HD , NG.Glad you got your tv going again Karl, was wondering if you could copy data from your A board now by SD card as in service manual 6.5 and post on here so I could copy to mine see if it fixes/changes my settings to a 42".
Would be greatful if you could thanks in advance.
As for your faulty A board, probably same fault as my original one, and would not know where to start a repair on it. But thanks for the offer of it.
Maybe it's selectable in there??Leave a comment:

Re: panasonic TX-P42X20B flashing red
Stick the other boards on eBay so others can use them. You should be able to get back at least your 50 quid.Leave a comment:

Re: panasonic TX-P42X20B flashing red
Any one know what might need changed on the a board to repair it or where to get the data from a 42" a board to change it on my 37" a board.
Or even how to change the resolution to enable full picture.Leave a comment:

Re: panasonic TX-P42X20B flashing red
OK. P board is definitely looking bad. Final check. Unplug PSU, wait 30 seconds, plug it in. Do you get some clicks from the relay?Leave a comment:

Re: panasonic TX-P42X20B flashing red
NO I dont, Here is what i get on P6 with the above in place..
pin1 (sound +15v) = 0v
pin2 (sound +15v) = 0v
pin3 (p+15v) = 0v
pin7 (F+15v) = +15.8v
pin9 (F+15v) = +15.8v
This is the same as before the resisitors where put in place.Last edited by karlpowell; 02-27-2013, 08:22 AM.Leave a comment:

As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
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 here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50

Hello Community!
CASE DETAILS
Promblem Signs: Backlight on 1 sec off 7sec > repeat && Red standby light: 1blink, off 3 sec, 2 blinks, off 5 secs, 2 blinks, off 3 sec, restart cycle
13V present on powerboard output. Backlight continues flashing after removing cables to pannel one at a time and even with both disconnected. NOTE: backlight STOPs flashing and remains on when connector between powerboard and mainboard (note Tcon built in) is disconnected.
Tried inserting firmware on USB and left it in for a few hours, but no change

Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...06-17-2025, 07:17 AM

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...
