Re: Lg 42pj350
I've checked resistance on all black caps and green things (sorry I'm not technician
) can you please mark on my picture what everything should I check? I'm desperate. I don't know which one is DC-DC converter etc... Thank you very much...

Re: Lg 42pj350
what parts are in repair kit, I would like to find out what is wrong, rather than changing the whole board.Leave a comment:

Re: Lg 42pj350
I've disconnected flat lead and unscrewed almost every screw and left 0,5cm gap between boards, nothing changed, tv turns off and on.Leave a comment:

Re: Lg 42pj350
Not sure which plug to disconnect, hopefully ot's one in bottom left corner o Y-sus board (red square on picture) or something else?...Leave a comment:

Re: Lg 42pj350
I measured resistance with unplugged plug (1), see picture....Leave a comment:

Re: Lg 42pj350
I don't get it. Please look at my picture.
1. First I disconnected plug 1 > TV stays ON
2. Then I reconnected plug 1 (that means all plugs connected) > tv turns off and on.
3. With reconnected plug 1 (that means all plugs connected) and disconnected plug 2 > tv turns off and on.
If I should test something else please highlight it on my picture.
Thank you very much....Leave a comment:

Re: Lg 42pj350
hopefully i get your point right, please look at my picture attached:
1. if I disconnect plug from power board to Y-sus board (yellow rectangle) the tv stays ON
2. if plug from Y-sus board is connected but i remove plug from X-sus board (red rectangle) the tv is turning off and on.
I assume now that Y-sus board is faulty, what can I check on this board?...Leave a comment:

Re: Lg 42pj350
Meanwhile I've measured voltage on power board on the connector to the Y-sus board with disconnected Y-sus board:
VS - 205
VA - 60
M5 - 5
and on the connector bottom right:
17V - 17
5V - 5
STB - 5
AC DET - 4.1
AUTO GND - 3.2
what else should I troubleshoot?
the buzz sound is going from center of the y-sus board.Last edited by sekino; 02-15-2014, 01:15 PM.Leave a comment:

Re: Lg 42pj350
I have replaced on power board:
2x 5W22R Vertical Ceramic Resistor
1x 3BR1565JF
but that not helps this time, but works fine with my LG 50pk350.
I have no backlight and can hear buzz sound when turning on tv for a second....Leave a comment:

I have clicking sound when turning ON tv, red light goes off and on. When I disconnect white cable from the left side of power board the tv stays ON but of course no picture. Anyone knows where can be the problem?... -

Re: Ps-50p96fd
What parameters should be the new caps? Same 10V, 2200 uF, 105 C? what does it mean LOW ESR? can u put some google image of good caps?Leave a comment:

Re: Ps-50p96fd
The one at the top is OK, it's just bad angle and flash.
The 2 caps bellow are on IMG117.jpg and also looks bad to me. Uploaded 4 more pics of these caps. One is definitely leaking other one looks close to it.
I've got good soldering skills and i can borrow multimeter. How can I really find out if these caps are bad or OK?...Last edited by sekino; 08-11-2012, 06:09 AM.Leave a comment:
