Re: need help with caps on a plasma tv power supply board
Fuck this forum, someone comes in wanting a little help and gets this? Fuck it I'm not going to stick around and be bashed over not knowing as much as the next guy on here. And I didn't listen to advice? I think you need to rethink and re read this thread. Won't be returning to this shitty forum.

Re: need help with caps on a plasma tv power supply board
Well I don't think that's right. People come to forums for help not to be cast away and basically told they're not going to be helped.Leave a comment:

Re: need help with caps on a plasma tv power supply board
No one? Also I need a place to order the caps I need. Somewhere that I can make a list of what I need and have it shipped to me.Leave a comment:

Re: need help with caps on a plasma tv power supply board
here are the pics you wanted of the PSU and one of the YSUS?, front and back of both, but now as far as the plasma goes (panasonic) i plug it in i hear a click i click the power button the red power LED comes on for 10 sec i then hear another click and the LED goes out and in that time theres no video or audio, thats where i stand with this TV as of now,
also included a picture of the 42in Olevia working and me testing it with my xbox, beautiful picture for an LCD TV, and especially a free one,...Leave a comment:

Re: need help with caps on a plasma tv power supply board
i have two olveia LCD tvs, one 32in (busted LCD works fully) and a 42in (no sound but fully functional otherwise)
my plasma this thread was started about, and a HP 21.5in computer monitor with and HDMI port that works but says OSD LOCKOUT when i try and change the source,
i want to fix all of these if possible, i know the TV with the bad LCD (32in) will more then likely be a parts TV unless one comes around with a bad board and someone sells it cheap as dirt, then ill salvage the screen, or...Leave a comment:

Re: need help with caps on a plasma tv power supply board
Yup mean the PSU? OK I'll get some pics of it I'll take as many as I canLeave a comment:

Re: need help with caps on a plasma tv power supply board
how can i test the PSU and make sure i didnt mess anything up? im wanting to do this because i used to mess with electronics all the time and im currently wanting to make a profession out of it, and would like some practice on stuff i have or can find for free,
i need all the help i can get, so anyone that will help me out with getting this fixed id be greatfullLeave a comment:

Re: need help with caps on a plasma tv power supply board
ok so ive removed all the bad (and a few good) transistors from the SN board circuit wise and tested them, the ones that i tested and thought they were bad tested bad still, and the good tested good, but how do i get these off the board without damaging it?Leave a comment:

Re: need help with caps on a plasma tv power supply board
I probed them on the diode setting, but I tested the diode by testing the leads one way then swapped. I youtubed how to do it not sure if I did it right. But I haven't taken them out of circuit yet haven't had time had to go buy a few things from radioshackLeave a comment:

Re: need help with caps on a plasma tv power supply board
also using the diode setting on my meter i tested the transistors on the SN board, and heres the ones i found that were bad/weak
D401, Q402, Q421, D421, Q422, C451, D481, D641, D642. these were tested while still on the SN board, i will be taking them off and testing them out of circuit to be sure, but are there any other known problems whith the SN board as far as having to replace bad or maybe going bad components?Leave a comment:

Re: need help with caps on a plasma tv power supply board
ok so i did what you said, here and the tv comes on with the red LED (not sure what the tvs led should be doing if it were to be working 100%) the red light inside of a jack on the A board came on, and a few seconds later the TV shut down
i was able to test voltage on the DCV scale and as well as the AC scale heres what i found
P6 connection
15Vs on DCV= 1.54 on AC= when power button is pushed it spikes to 9.5 then down to 3.0 untill it shuts down

Re: need help with caps on a plasma tv power supply board
also what settings on my multimeter should i be using to test with? im assuming 20k ohm? or the AC current setting?Leave a comment:

Re: need help with caps on a plasma tv power supply board
alright, i got back alittle late to mess around with it tonight so ill post tomorrow when i get up and around to it, thanks for the help tw2005Leave a comment:

Re: need help with caps on a plasma tv power supply board
Alright I'll test everything out when I get home in a bitLeave a comment:

Re: need help with caps on a plasma tv power supply board
so since i didnt get a response i started testing the transistors on a 20k ohm setting, and will the transistors ever have pins that will read short if theyre not shorted but its really the way they work? or is it just shorted and replace it?Leave a comment:
