Re: LG 42PJ550 Click

this will be fine as a alternative yes?

Re: LG 42PJ550 Click
no nand/flash device means it's looking for a usb-stick with the firmware file on it.Comment

Re: LG 42PJ550 Click
no idea - usually whatever it's named when you get it in the zip file.
if you get no usb activity, is the usb port powered?
if not then maybe your missing some of the switched 5v.Comment

Re: LG 42PJ550 Click
from what I can tell all appear fine just the mainboard is at fault, I can't find any info at all about the message in teraterm looked on lghack and a few others
from what I can tell if the mainboard is at fault the usb port will never get power but I guess i'll find out tomorrow as the mainboard has been sent out today
also looking through lghack and others recovering a bricked board isn't done by usb but from inside the linux system on the board via teratermLast edited by anotherdude; 04-25-2014, 10:32 AM.Comment

I have a Dell Latitude 5511 laptop, and lately, a faint but clearly audible electrical (crackling) noise comes from the motherboard, similar to the random clicking coming from a mechanical hdd's heads moving inside it.
The laptop shows no signs of malfunction, and clearly this is electrical not mechanical, so my suspicion goes to a dodgy component in the power rails (a capacitor or a coil?). I fear this could develop into a serious damage.
Any advise on how to narrow it down?
The schematic is available here:

I really hope someone will be able to help me?
I have recently moved house and dismantled a working 5.1 home cinema
system. Unfortunately when putting it back together again I get no
sound out of the sub, I'll try and give you as much (probably too much)
information to hopefully allow you to sort my problem, or at least
point me in the right direction.

Have a MSI PS63 Modern with a board number of MS-16S11. Havent been able to find schematics or boardview for this machine, but would love to try to get it fixed.
When the power button is pressed, the machine attempts to boot - keyboard backlight turns on, then there is an audible click and the board reverts to a power off state. Press the power button again and the same thing happens. Have pulled the board from the machine trying to locate the clicking noise by sound, but it appears to be coming from everywhere on the board and I cant pinpoint its location.
The board... -
Dear all,
For a friend I'm trying to repair an Acer Swift 3 laptop (SF314-42). I'm not a professional, but have some experience (both as amateur and professional) in working with electronic design and repair of musical instruments.
The issue with the Acer laptop is the following:
It was bought new and used (not heavily) at home for about three years. After normal use, it was put to sleep, connected to charger and left over night (just like any other day). The next morning, the laptop would not wake up from sleep. Instead, when pressing the power button, the power... -
Hi guys,
I've got a LG 42PJ550 that went down on me over the weekend. The symptoms are it just keeps clicking and won't start. It was intermittent for a few hours and would cycle on and off and randomly start. Now it won't start at all.
I bought a repair kit which included 2 x 22ohm resistors for R927 & R929, a voltage regulator for IC301 and a diode for D304. I'm also waiting for some SMD resistors to arrive which is another 'known fix'.
I'd like to bow to the alter of the experts here and ask your thoughts... any voltage checks I can do to narrow...
