Re: Panasonic sc tnpa5081 rebuild

No need to desolder R819,R820,R818,R919,R799,R798,D792,C797,IC792,IC793,because R915 on Sd board not placed from pin 7 SD42.But must be placed R720-22R near connector SC46.So changing version AW to AY is easy.Solder IC564(looks like TC7SH08FU-Toshiba,marked H2) and solder R720-22R from output IC564 to pin 1 SC46.TV works with full screen!

Re: Panasonic sc tnpa5081 rebuild

Thank you for your reply tw2005.You are absolutely right.
In AY version is placed IC564 (smd code H2 - AND gate).Output signal from IC564 is marked AA_SEL2 and via SC46(pin1) and on SD board via opto PC904 and IC901 (marked c14 - inverter) delivered to buffers.AA_SEL2 I measured only on SD board.SU board is powered by a signal AA_SEL via pin 9 SC46.
In AW version, the circuit IC564 is missing.
And the second difference I've found is 10 components placed right below the jumper SC50. R819,R820,R818,R919,R799,R798,D792,C797,IC792,IC793....

Re: Panasonic sc tnpa5081 rebuild

Hello,I have TX-P50VT20E Panasonic plasma TV.Try to repair SC board,but no success.Changed all list like tw2005 wrote - 31 component.TV turn on with full size of screen,after 15 minutes turn off with 7 blinks.My board number is TNPA5081 AY version.I think is 3D version.I ordered from ebay TNPA5081 version AW(2D),plugged in and I have only half upper image.Is possible to swapped in some components like IC564,and unsolder some like IC792 ? Or this version of board not work in this model?Sorry for my bad english.Thank you.
