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!

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
