Hey can anyone tell me how I can check to see if my strw6765 MOSFET is good I have it out of the board cause my bad solder job the solder melted and joined two pins together so it poped. I am pretty sure it's bad but before I order one I wanna make sure. Plus I took it out to re solder it and fix it the proper and clean way.

Re: How to check strw6765 to see if its good
Thats an IC, hard to test, but check between pins 1 and 3 with an ohm meter, if its shorted the ic is bad.
Here is the pdf of the device. -

If you shorted two pins with solder and powered it on and it went up in smoke then it's bad for sure."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Yea I think it was on the 6765. Cause it looked like they were touching but I'm not sure. I guess I can start with that one and go from there.Comment

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -

Hi, I have a Denon AVR-X3600H I'm trying to repair. I have no electronics repair experience but I have a multimeter, service manual and a will to fix it (https://device.report/m/d5de8c00e617...f63147aba9.pdf)

Only digital symptom I can tell is it will soft lock when in the Speakers/Test Tone menu and be unable to adjust +/- db during the test tone.
I've followed the trouble shooting guide, audio check... -
My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
Then I get an idea to take it apart and clean boards from dust.
In side of Tv was not so bad, I take compressed air in can, and gently blow up.
Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher... -
Hey guys, grateful if you can help me figure out issue with the following:
Board reference: AAL15 LA-D071P rev 1.0 (with dGPU)
Backstory:
Laptop came in as dead. After diagnosis, 5VALW regulator was shorted. Regulator was replaced and laptop boots without issue.
However, when trying to boot into windows, I get WHEA_UNCORRECTABLE_ERROR and laptop reboots. Sometimes it would start booting into windows and give the welcome message (fresh windows installed) but would then give BSOD with above error and restart. Sometimes I get MEMORY_MANAGEMENT BSOD and...
