Re: Panasonic TH-58PZ800U major problems

does it give you a sd/su buffer bypass procedure to run the sc without buffers connected?

If it's a buffer board then isolating it should mean the TV will turn on?

Yes, there is an isolation procedure, But I will need to pick up some clamp jumpers in order to do it.

I guess unless you can use wire to screw into VFG posts and then maybe tack the other end or wire wrap. next gen has the sc50 jumper to do same job

I think loosen the vfg bolt and put one end under and tigten down, wire wrap or solder on that inductor lead.

I got some clamp jumpers and tried isolating the SD board by disconnecting SD42, SD46 and SD11, then connecting the leads to a VF Ground and the L108 coil of the SC board per the manual instructions, but I still get 5 blinks. Also, as I understand it, if I disconnect the SD board with no jumper connection, I should get a 7 blink code on this model, but even that still gives me 5.

Re: Panasonic TH-58PZ800U major problems

So I'm finally getting around to giving the testing flowcharts another go just to make sure I'm getting accurate results. Clearly a little lateto be asking stupid questions, but considering my complete inexperience, I have to ask. When testing connections (ex: measuring the resistance between pin 1 of connector P12 on the P board and ground), do I disconnect the P12 connector to test the pin or leave it connected and stick the lead in next to the wire? And what reading indicates a short to ground? No change (near zero) or an active resistance? I know these are basic noob questions, but, well, I'm a basic noob.
