Re: LG 60pb560v plasma tv no picture
hello again sorry for the late reply.
i m going to start over again because it is confusing right now . I have made pictures firstly of the z-sus board. can you help me to determine if it is good or bad?
how to measure and what to measure....
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: LG 60pb560v plasma tv no picture
hi all,
didnt got any further with the tv.
didnt ordered other boards.
the pictures i made where from the ysus board.
so i have to measure the zsus board.

Re: LG 60pb560v plasma tv no picture
hello hope everyone had a good christmas :-).
that are indeed OHMS so that means they are bad. but in the first two pictures if those read 0 is that bad too? the first two pictures are of the same component.
i m going to do the rest what you have said but it can take a moment for me to reply.

Re: LG 60pb560v plasma tv no picture
measured some things there are a few ic that go to zero, i dont know if this is normal. so i made pictures of them.
also the transistors i have a question about. the ones that have a red circle around them. one is measuring both ways a value of 500 and the other measures one way but not the other way....

Re: LG 60pb560v plasma tv no picture
Hi,
I'm going to measure that straight away. Thank you for your good explanation of how to do it.
I can't determine a test picture because it goes off very fast just a sec or so and then goes black.

Re: LG 60pb560v plasma tv no picture
i have found something strange,
when i only connect the bottom one i get the snowy picture look ok to me.
but when i only connect the top one i get a weird half snowy picture with a littlebit color in it. Made a picture of it verry weird
ill post a picture with it....

Re: LG 60pb560v plasma tv no picture
vy 213V of what i can see my meter isnt verry fast and than it stays at 183V
ZBIAS stays at 124V nothing above that.

Re: LG 60pb560v plasma tv no picture
hello,
i tried and solderded the points together. what happens is that it shows a snowy picture for one second and then drops black again. so the screen also looks good. no cracks. and we have a little picture on it thats a small step forward.
what is your opinion about this? also the green led it comming on. 3 times short 1 time long and the goes out for a 2 seconds and then repeats the same cycle.Last edited by vivalabam88; 12-18-2018, 01:42 PM.

Re: LG 60pb560v plasma tv no picture
hello thank you for your reply, i have measured the buffer boards and they look ok. the only thing i get is with the bottom buffer one (there are 2 top and bottom). is that there is a reading when i measure it is about 900 on diode mode, NO shorts that drops to zero. (made a picture of that board.
the vscan i cannot find, but the vzbias i have made a photo of.
the zsus board i have measured again. one side it reads 10k and the other side it reads 1.4k for the most transistors. like Q301 for example.

it was d201 i measured both sides go to 0 red and black switched from left to rightLast edited by vivalabam88; 12-14-2018, 12:54 PM.

Re: LG 60pb560v plasma tv no picture
hello and thank you for your reply,
I hope i have measured it right and i didnt find anything wrong on the ysus board.
but i think i have found something on the zsus board i have made a few pictures of it. i hope you can tell me if i have done it the right way....

Re: LG 60pb560v plasma tv no picture
hello,
i m back again. orderd another logic board but still the same problem it is not new but used.
not a single blink from this one nether. is there something i can try or measure?
thank you

Re: LG 60pb560v plasma tv no picture
Tried to do what you have said about disconnecting al the other ribbon cables but still no changes. The only thing I measured was that the voltages dropped to 1.7v and 3.3v on the logic board.Last edited by vivalabam88; 12-06-2018, 04:30 PM.

Re: LG 60pb560v plasma tv no picture
Just also tested the sound. And it works. Plugged my ps3 in and sound is there when I switch screens that I don't see

Re: LG 60pb560v plasma tv no picture
I have measured the voltages and they are ok 3.27 volt and 4,97v on the logic board. Disconnected the main board but still no green led. The screen I still need to look at for cracks didn't do that yet.
Added some pictures hope they are good.

Thank you for your fast reply . I'll post pictures as soon as possible. And I will check the voltages too. And let you know what it is.

Hello everyone,
I have a problem with a TV of mine. I would try to explaine as much as possible.
When I put in the power cord. You hear relays clicking that's normal. The TV is starting up right away but not with a picture.
You can use the power button on the TV itself to turn it off again an it reacts normal and shuts off.
You also can turn it on again with this button.
Also with no picture coming.
What I noticed is that the logic board never gives a flashing green led. It also doesn't matter if I disconnect the y-sus and z-sus boards.
