It is not always possible to do so from the normal system menus.

Stick the other boards on eBay so others can use them. You should be able to get back at least your 50 quid.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonic TX-P42X20B flashing red
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.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".

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.Comment

Re: panasonic TX-P42X20B flashing red
That's a shame, hope the data copy works if you get it, total size of my data copy files from my 50 was 112kb. hopefully someone can help you out.Last edited by tw2005; 03-24-2013, 07:32 AM.Comment

Re: panasonic TX-P42X20B flashing red
Out of curiosity, when you toggled to the 42, it was red. Did you hit ok, it changes to black and then restart the tv? I'm not brave enough to fool around testing mine and changing to 50 just in case I lose the picture or the menu goes off screen otherwise I'd have a go.Comment

Re: panasonic TX-P42X20B flashing red
Sure I tried that but did not stay as 42 when switched back on. Was a little while ago now trying to mind from memory. Not able to try it again just now. Even tried changing all the settings possible to what was shown in service manual but think it may be an unchangeable setting in eprom or something as to amount of pixel lines it shows on the screen (37" 720 lines 42" 768 lines). Then it just copies the top 48 lines on the bottom of the picture.Comment

Re: panasonic TX-P42X20B flashing red
That sucks, an option that's not an option. it'll be interesting to see if a data copy works then.Comment

Re: panasonic TX-P42X20B flashing red
Just a thought there tw2005, if you copied the data from your 50, could you post it on here and I could give it a try out of curiosity and see what happens. Should have asked you this earlier, doh. I have a copy of mine as it is so no problem going back the way if I had to. Or I know where I can get another board at the moment if I really had to go that way. But the guy got the whole TV for £35 with cracked screen and possibly a courier cost but now wants £40+£5 postage for each of the boards he took out of it, and on his listing he has it stated as working board taken from a NEW TV with a cracked screen. But the guy that sold the TV had been asked by a friend to skip it for him, so it's not from a new TV as per his listing.Comment

Re: panasonic TX-P42X20B flashing red
I've come to realise everyone selling cracked screen parts on eBay lies about testing them. :/ I've received a few dud boards that after a short argument I've got a refund and lo-and-behold a new board fixes the problem. Frustrating though.
I'd guess that a 50" panel would be worse. It has 1366 columns (as opposed to 1024 rows on both 42" and 37") so enabling that may cause loss of HSYNC = scrambled picture.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonic TX-P42X20B flashing red
Lies, lies everywhere Tom. I think you and I have established that fact both Ebay and Stri & ship businesses. SJ is about the only one I feel is testing as much as possible and from the majority of parts they do appear to have come from brand new damaged in transit TVs. Some of the older Tvs maybe not.
The NZ A board I have which I inherited was an EBAY advertised as essentially new from damaged in transit screen. A lie- go into the service menu and it had in fact clocked 3000hrs.
Either the seller does not know it's logged or assumes the vast majority of buyers would not know how to find this information.
Some of these newer TVs with cracked screens on Ebay it would not surprise me some creative people intentionally crack the screen to claim insurance when they find out how expensive the repair is going to be.Comment

Hi peeps, have a Panasonic TX-55CX400B here, guy I got it from said he tried to turn it on other day, and no backlights.
When I received it last night, I plugged it in, and it came straight on and appeared to be working fine, so knowing this would only be temporary, I left it running for a good few hours, and they eventually went off. I tried turning it off and back on again, and this time the backlights started flashing at a steady continuous pace. So I turned it off and left it overnight as it was getting late.
This morning when I turned it on, same problem, backlights... -
In the Panasonic service manuals, both in the board schematics and in the part listing, the part numbers that are given are Panasonic part numbers instead of the actual part numbers.
This is especially annoying for small SMD components like diodes and transistors when you only have 1-3 digits printed on the component body.
For an example, look at the attached PDF.
Do you have a way to cross reference the Panasonic part number with the actual part number?
Thanks....07-03-2023, 08:16 PM -
I have a Panasonic TX-L55ET5B that wont turn on.
When you press the power switch on set, you get the blinking green light, then it goes solid, the display comes on and goes off 3 times, then it goes off completely and the power light slowly flashes red continuously.
If I hold power button and turn it off, and back on, it does the same as above.
When the display is on, there is a noticeable noise from inverter board, that is only audible when screen is illuminated, it goes off and back on with the screen.
I have attached pics of rear and... -
Hello all. Only my second post.
I have a panasonic CF-20C5142VM which was booting to bios with no issues. I needed to add an ssd that was not initially being recognized by the bios. Found a link that suggested that I disable uefi mode and clear keys then to reboot to allow bios to now see New ssd. After restarting, screen is entirely black with no image. Found another post that suggested unplugging bios battery because some remnants of the bios may still exist in other parts of board but did not fix issue-screen is still black.
Anyone run across something like this before?... -
un65tu7000fxza - I am experiencing the flashing red light on the power led. So I purchased the replacement kit for the mainboard and power supply. I still experienced the flash red power light. So I purchased a new ribbon cable, The flashing light stopped for a minute, I could hear sounds on the TV but no picture. I did the 60 second reset and it went back to flashing. What could possibly be the issue now? All the LEDs are lit up from what I can see.
Thanks for all responses.
