TC-P50V10 SU SD Board Resistance High

[micker]

Hi, Fixing a Panasonic TC-P50V10 with a 7 blink problem. Have replaced SC Board and Power supply board and now checking resistance of SD/SU Boards according to Panasonic fault finding guide.

The SU board is reading 6.34 MegOhms between Pin 2 on SU41 and VF_GND, the Panasonic guide says this should be 2.1 MegOhms.

The SD board is reading 6.28 MegOhms between Pin 9 on SD42 and VF_GND, the Panasonic guide says this should be 2.1 MegOhms.

Have done the resistance continuity tests between ground and the panel ribbon cable outputs outputs and no beeps!

Would these high resistance readings class the boards as defective or should they be ok as the guide states low resistance is faulty?

Thanks.

Re: TC-P50V10 SU SD Board Resistance High

This may help someone else.

Went ahead and hooked up boards and SU/SD are fine with these readings, set powered up and worked perfect.

Was long process have changed P Board, SC board, SS board and A board, which by a process of elimination, each showed a defect.

Also replaced SC board with a TNPA4782AB, in a V!0 which uses a TNPA4782AF, found info on the forum which confirmed that G10 SC boards worked ok in V10 models, thanks for that.

Hi, I was also about to replace the SC board in a V10 with a TNPA4782AB, but it appears the difference is the size of the heatsink, which on the AB board are too tall to fit inside the slimmer V10 cabinet. Did you move the heatsink over from the AF board?

I assume the small heatsink is the reason the V10 needs four fans as opposed to two fans on the G10.
