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!

Laptop is HP Envy x360 13-bf0013dx, hp website link, it's an i7-1250U with 8 gig onboard ram.
Platform: ipa32 la-m024p rev 1b
Originally you'd plug power supply into it and it would take up to 1.2 amps and then drop to 200 milliamps and then go back up again to 1.2, staying all the while at 5 volts. Pressing power button would results in power LED blinking amber 3 times. 3.3 volt rail, 5.1 volt rail present, main power rail 8.8 volts. Power button test pads near EC chip 2.7 volts.
I found a short on the other side:

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.
I am diagnosing my personal laptop, because it wont power on and no leds light up.
At the dc-in there are 8 pins, 1 and 2 shows healthy 19.66 volts. The next three are ground, but the 6th one shows .283 volts. This is strange to me, it should be 3.3 or 5 or aome volts not 0.283v. As I am new to this, I would like some guidance. Please someone advise me on what to check next.
Oh the boardview and schematics I am using is for a similar model as I cannot find the proper one anywhere. Quanta DA0P5HMB8F1 rev F. Nowhere on the internet.09-23-2025, 12:13 PM
