Hello Guys
I have a ASUS Rog strix laptop that I bought recently to fix and the previous owner spilled water on it . He brought it into a repair shop for them to check it out and instead of fixing it they damaged the battery connector of the laptop ! Other than that they damaged damaged nothing . But since the liquid damage the laptop only turns on and the keyboard lights up and then immediately turns off. I really want to repair this laptop and I also have experience in repairing phones etc and laptops and a bit of soldering but the diagnosing part is where I need help with and... -
Hi everyone,
I'm currently repairing a NEXIQ USB-Link 2 that was physically damaged due to crushing. After a thorough inspection, it appears that only one component is visibly damaged: the T5 component, located right next to the Mini-USB port.
It's a 4-pin SMD component, with one pin at each corner, aligned front-to-back along the USB port axis. Unfortunately, it is broken, and there are no visible markings left on the part to identify it.
I'm looking for help with the following:
The exact identification or part number of the T5 component

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.

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... -
This tv is with sound but no picture. When light shines on the screen, we can see the image. This is a typical backlight problem. I opened it and found quite a lot of the leds are damaged. But the damaged ones are all shorted. No one is open. Is there a special reason? (From my past experience, both can be happened)
When I supply 3V to each of the good leds, the currents range from 105mA to 154mA. From these figures, I think the leds are 3V and about 0.5W. I plan to replace all the damaged leds only (because the price of the led strips is very expensive), but I could not find 3V 0.5W... -
Hi All. I had a Roland KR-3500 Digital Piano (similar to the KR-4500) that exhibited a Crackling audio sound on all keys. After reading somewhere about someone with a similar issue who had replaced all the Electrolytic caps I decided to also go down that route. (Spoiler : It worked !) After some basic troubleshooting I determined that it could be noise feeding thru from the Keyboard scanning since the Demo tunes played back undistorted and the Audio amp / speakers were fine ( Inserted an Audio signal into the rear Audio input). After extracting the main board from the shield, I replaced 7 Capacitors...04-30-2024, 08:20 PM
