Panasonic TXL42B6B - Flashing display.

Hi folks,

Got one in where the screen flashes on and off for several seconds then set cuts to S/by with Red Led flashing once every three seconds.

Have a horrible suspicion that it's another duff Led backlight issue, but surprised it doesn't cut straight away - Any thoughts - Thanks - Chris.

Hi Chris,

Code 1 is indeed a backlight SOS. Just curious if it uses a TNP4G549 LED drive board. Have a bulletin if it does.

Hi Chris,

Well then, see if this is useful.

Hi Bruce and thanks,

Had a shufti and the pair of Fets seem OK - Note they're GK1FD328s (Can't find specs on 'em)

Thinking of trying isolate the Led strings to check individually and wonder if anyone has a service manual as can't find a freebie locally.

Noticed that a chap on line had a similar problem where repair folks wanted to charge £100 more than the set cost for a screen replacement - Chris.
