Re: Sanyo Plasma DP50741-01 On/Off problem
Do I need to replace the sc only or do I need to replace the two buffer boards that it attaches to.

Re: Sanyo Plasma DP50741-01 On/Off problem
If I put my DMM on continuity SC2 reads OL.. on SC3 there are three pins the one closest to the top of the board ill call pin 1. Pin 1 is bottom ground it has continuity when I touch the heat sink and solder around screw holes(I have the board out). Pins 2&3 are measuring the same they have continuity on the metal spacers the the buffer boards ground too and the power coming in from vsus.Leave a comment:

It is 30kohms if black is on gnd and red on vsus and if I switch them it reads 2.9kohmsLeave a comment:

Re: Sanyo Plasma DP50741-01 On/Off problem
Ok so the new board is definitely in and the old board is definitely bad befor I had to disconnect the ysus and xsus board inorder for it to stay on a little longer (6seconds compaired to 2) so what on my ysus board can I test ? I still do not see any cosmetic damage to anything on the board and the SC2 vsus to -gnd reads 31K ohms.Leave a comment:

I'm sorry I just remembered I don't know which one is new or old but I just swapped them out and no change even tho clearly the boards are reading differently.Leave a comment:

Re: Sanyo Plasma DP50741-01 On/Off problem
Yes I read that too and didn't understand myself, I ment 0 ohms as = nothing. Not the actuall number. I'm sorry for confusing you and myself. On the old board xsus the ohms between tpvsus and -gnd is OL. And on the new board it is 0.000 ohms.
And don't worry one bit I'm not blaming you at all I really do appreciate your help.Leave a comment:

DEEP BREATH......That did not fix it.....im about ready to do some target practice. I received the new xsus board and installed it and the same symptom's. I checked and tripple checked and the tpvsus to gnd and the old board doesnt have any continuity and the new board does. So i know that was a problem but the tv still does not turn on. So far i have replace the power board main board and xsus board what else can i check, or what can still be wrong.Leave a comment:

Re: Sanyo Plasma DP50741-01 On/Off problem
Thank you for getting back to me I checked my x Sustain tnpa5072 ae board and I tested the connector that comes from the powe supply (TPVSUS). On the power supply they are vsus, gnd, and +15Vc I get 0.000 between vsus and ground. And OL between +15Vc and ground. And OL between +15vc and vsus.
Then I checked my ysus TNPA5063 AB and tested connector SC2 and I don't get continuity and the ohms jump aroundLeave a comment:

Sanyo Plasma DP50741-01 On/Off problem
Hi my name is Sean I am new to this forum and would greatly appreciate any help I can get on this. From the start, one day i was watching TV then it shut off. Tried turning it back on and clicked (green led came on) then 2 seconds later click (green led turned off).
I have done a lot of research and pulled out my muti-meter and started testing what i could. The one thing I knew for sure are my fuses were good....
I searched for everything i could poke at and checked all caps look far any signs of swelling or burnt connectors or anything. If you took one look at my tv it looks... -
