Re: Lg 50ps3000
I'd consider the possibility of a missing drive signal on the Y-sustain, or a signal between the buffers going missing.
Shame you're not closer to me, or I'd have it off you

Re: Lg 50ps3000
back on this again, TOM, because you said drive signal, thought i'd have a check on the cables.
on checking the ribbon cables from Y_SUS to top buffer, pulled it out and the cable has some damage to the tracks, some broken, and even some bits missing.
so my question is, where can i get new replacements ?
tryed to cut the old ones back a bit, but then there is not enough contact, and can't peel the back off to reveal or make longer contacts.Comment

Re: Lg 50ps3000
Probably the only place is a TV breaker who might have kept the cables. They are custom and very expensive in low quantities... I've had the same issue on an LG DVD player so wonder if it's a common issue with LG's cable supplier. In my case the metal contacts just broke off completely and wedged themselves in the connector.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi all,
this unit comes from a samsumg LCD TV LE32C530F1W which stopped working after making a strong noise like something was exploded inside of it.
I opened it and found that fuse FP801S was blown, capacitor CP814 was completely disintegrated and MOSFET QP801S was shorted.
I replaced all of them and instead of the fuse I connected a 100 Watt bulb. Then, without connecting it to other TV boards, I switched it on, but the bulb begun to blink.
I thought that maybe the bulb was somehow interfering with the normal operation of the power supply, so I replaced it with a fuse,... -

Hi everyone,
Brought a non functionnal PS5. Apparently only a bad PSU...
No beep, nothing.
After some tests i found this :
- PSU is fine (12 volts stable)
- 12 volts line is shorted
- DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
- By the way, nothing change. No signal, no power, no beep.
Mesuring all rails with my workbench psu (12 volts input)
- 0.00 amp drawing
- 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is... -
good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?
By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...
