Re: Panasonic 58-TXAX802B Stuck on Panasonic Logo
Hi lotas
Thanks for your prompt and efficient reply.
Looks like I have zero chance of changing that BGA IC
Is it a programmed device would you know?
TIA

Re: Panasonic 58-TXAX802B Stuck on Panasonic Logo
Hi
I thought IC1600 (25Q64) was the eMMC - can you advise which chip this actually is please?
Thanks

Re: Panasonic 58-TXAX802B Stuck on Panasonic Logo
Hi
Does anyone know what else would cause the stuck on Panasonic logo followed by 13 flashes other than the IC1600 (25Q64FVSIG) on a TX-50AX502B set?
The service manual does not even have circuit diagrams.
Thanks for any info....

Re: Panasonic TX48C300B - recovery F/W
Hi Diah
Thanks for pointing me in the right direction - what I took as an error code of 10 flashes was in fact the normal startup of this set and of course there were no backlights.... - I checked around the MP3394 which seemed to be shutting down early as the VLED didn't really hit high enough to light the LED's. The OVP pin seemed to reach 1.25 volts so I checked the R's on this pin - 2 x 390K and 1 x 6K8 - I removed the 2 x 390K's off board to check and they seemed good so I soldered them back in - next time I checked the LED's...Leave a comment:

Re: Panasonic TX48C300B - recovery F/W
Hi
OK have removed 26L1606E and programmed chip with code (using CH341a and AsProgrammer s/w) - re-inserted into board but symptoms are the same - power LED pulses x 10 times at power on.
Attached is a pic of the labels on the board.
Anything else you can suggest/advise please?
Thanks again...

Re: Panasonic TX48C300B - recovery F/W
Hi
Thanks for the file - however still no joy - the TV just flashes the re power LED 10 times.
Main board Vestel is 17MB97 and the U81 on main board is a 25L1606E and the file implies 25L1605... - does that matter?
Panel label shows as - 10096599 - 23269708 96 48 27366448 DIJ.
Any help gratefully received.
TIA

Hi
I also get the screws from Farnell - 249-4525 (approx. 6.5p per screw if ordering 100+)

Re: Panasonic Plasma TC-P50GT30 7 blinks SC board shorted
Hi
I get my IGBT devices direct from Panasonic - only about 80p each.
(p+p £3.50 per order)
