by r2digitalI have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...Yesterday, 03:50 PM

Hi,
Trying to work out if this is TFT problem or TCon issue.
The TV powers up but the top half of the screen, from the right it is OK, but as you look across to the left halfway across it starts get duller and duller until it is very dark on the lefthand side, currently I trying to clean the remote as it seems to have something film wise on the pads stopping it from registering buttons pressed.
Also when changing the screen size of Windows PC display to say to a smaller pixel sizewindow, the original window displayin the top left stays/takes a few seconds to disappear?...2 Photos04-08-2024, 03:40 PM -

by unimatrix93Hello everyone,
I'm trying to fix a small LG TV with wierd issue.
So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
The BL turns on, the tester shows around 80V. So the led strips are okay it seems.
Now I started to suspect the BL driver IC which is a MP3378.
I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.

by RotVikHello everyone, I come here in search of wisdom and hope.
I got this laptop with charging problems, apparently it charged ok while turned off but it would not charge while powered on, anyways I was doing initial measurements looking at the voltaje on the ID Pin, it is a 135W DC Adapter and the pin actually measured 1.9V that looks ok, anyways, while doing that, I accidentally shorted the ID pin DETECT(ID) with one of the 20V pins, sparkles and it automatically killed the TVS Diode PD102, and also made a cute burning hole on the middle of the KBC or EC chip UE1, it is a IT8227E-128,...Today, 01:04 PM -

by paparazzo79Hi guys.
I own Alienware 17 r3 6820HK GTX 980M.
I purchased it recently tried some gaming (Rise of the Tomb Raider, Serious Sam) and after 10-15.min games freeze, but I could hear audio from game.
Now I am not yet at home, but when it happens I do get separate window error message and will post it later.
Then again there are moments when I could play for like an hour and no errors.
From my experience reading about this issue, this means my GPU is dying, correct?
I installed most recent nVidia drivers.
Temp of GPU while gaming is max 76 C, but usually around...Today, 12:07 PM -
by chaos-theoryI have a card that does post at all, the owner said it does go into windows but it gets stuck on the logo with artifacts, I have no idea if he is lying or not... I tried the card on my pc and it does not post at, no beeps, no bios nothing just all fans turning and nothing else. I tried plugging DVI or hdmi but nothing, I tried unplugging the 8 pin plug from the power supply and it's the same thing.
I just want it to post and get into the bios at least.
Forgive me if I am wrong, but I tested the 3 PCIe 12v power pins on the left(550ohm) and the 4th one from the right 3.3v (400ohm),...Yesterday, 02:42 AM -
