Re: Panasonic TLX-04244B
Can you give us information on what LCD panel this model uses and what inverter it uses. Pictures would help. Sounds a lot like "2 seconds to black".Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -
Re: Panasonic TLX-04244B
Not sure what LCD panel this model uses but it has 2 inverter boards the master board is part# V1T71043.50 rev 2 and the slave is part# V1T71043.51 rev 2.Comment

Re: Panasonic TLX-04244B
Can you post some pictures?
Quite possibly uses an IPS Alpha panel (Panasonic's own LCDs.)
How sure are you it's a Panasonic? TLX-04244B is a Polaroid model.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TLX-04244B
OK, so the first step is to post some pictures.
I will forgive you this time for mixing them up

Re: Panasonic TLX-04244B
thanks for your patients, do you know of or have you seen or heard any fixes for this problem on the Polaroid tlx-04244b. Almost everyone I saw posted has the same problem with the backlight going out.
Thanks...Comment

Re: Panasonic TLX-04244B
No, I do not see many Polaroid, they are rare in the UK.
If you start with pictures, we can go from there.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TLX-04244B
The problem I found with this LCD tv is they installed CCFL lamps without soldering them. They just snap in and over time they start to arch. That's the buzzing sound you are hearing. The arching causes the inverter to shut down. I took the time to disassemble mine and carefully lifted each bulb out of their sockets and cleaned them. There are 18 bulbs in all. Be careful because these bulbs are extremely fragile. TV is back on and working.Comment

Re: Panasonic TLX-04244B
Thanks alot for the info. I was leaning that direction since the only 2 people I found that got them to work had ccfl problems. Sounds like a difficult job but better then throwing money into invereter boards.
Thanks again, I'll check it out...Comment

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... -
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 😂.

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... -
Good day,
I have tried to remove BIOS supervisor password from Panasonic Toughbook CF-33 mk1. Model number CF-33AENABTG, unfortunately I don't have any other info.
I read the BIOS using afuwin, edited it and tried to flash new edited BIOS using afuwin. Unsuccessfully. Afuwin showed "Error: Problem erasing flash." starting with 0x00040000 and stoped. Then I tried many other options to flash BIOS from Windows without any luck. Finally i rebooted the device - and no post. Afterwards I have read the corrupted bios chip (MX25L12873F) using EZP2010 programmer.... -
