I have an LG Plasma TV with a shorted Z sus board. I found that the IPM is shorted out. Does anyone know where I can find either a new Z sus board or IPM replacement?

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
SAMSUNG TV PS51E550D 1W,
Symptoms: the panel is on but no picture, fuzzy color vertical lines at the black background at both sides of the panel. Very similar to this:
Disconnecting left side of the panel fixed the right side which went on and displayed picture although with vertical black bars coming from the middle X-BUFFER panel at the bottom of TV and the same 1 fuzzy color vertical line ~ 0.11 inches long and a few 1 pixel black bars. The disconnected left side showed fuzzy colorful bars, may be some glimpses of the the correct image from menu at the right side... -
Hi all,
I'm a beginner at laptop repair. I bought a MacBook Air A2681 that doesn’t turn on, just for practice. PPBUS_AON and the other always-on voltages are present and look fine. I did some diode mode measurements and got unusual readings (compared to reference values I found online) on LC320 (44mV) and L82D0 (40mV). LC320 corresponds to the PP5V_S2 power rail, and L82D0 to PP1V25_S2.
I injected 1V (current limited to 100mA, the board consumed around 86mA) into PP1V25_S2 to see if anything would heat up, but everything seemed normal. I did the same with 5V (current limited... -
This is MS board M1029273-001. I'm getting <.2 ohms on output of the second mosfet. Looking at a schematic, I injected 1v/5a to the resistor pin where this mosfet connects to, and it is drawing 3.7a but the only thing getting hot in the thermal camera is this resistor which surprises me.
Where should I be looking from here?... -
Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.
I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :
D608, good
D618 RF101L4S, good (See warning 1 below)
D619 RF101L4S, good (See warning 1 below)
D865 RF101L4S, shorted (See warning 1 below)
