I am looking to replace capacitors on a japanese laptop (an NEC PC-9821nr15 /S10). I have a couple components whose appearance is similar to other SMD capacitors I've seen on 90's electronics like the Sega Game Gear, where its an electrolytic capacitor encased in a small enclosure and glued down...
This was a "gift" from my brother. He got it for free from a computer recycler. The card actually works other than the game port.
I agree regarding repairing surface mount gear. Thankfully this component is through hole, so a little hot air, fresh solder, flux, and a desoldering pump should be...
I'm working on a Creative Vibra 16 ISA sound card (CT2260) and it appears to have a damaged resistor network at component RP3. The component has "T1A 102J" printed on it. Its a 5 pin SIP. I can't find any info on it via google and don't know the specs to try and order a replacement. Any help...
I have the following Motherboard: https://theretroweb.com/motherboards/s/pcchips-m560-v3.x
Last time I went to use this PC, the computer unexpectedly locked up, then became very unreliable when attempting to boot and post. After doing a visual inspection, I found some bulging capacitors. I went...
Apologies for the late reply. So tl;dr, I ended up taking an educated risk and reinstalling the diode and along with some other replacement parts. I lucked out and am up and working.
This zener diode was a part of a power supply for a CRT computer monitor that experienced capacitor leakage from...
I won't be able to tonight unfortunately. Please don't keep yourself around late on my behalf. I'll read through the advice you've offered more closely later in the week and respond with how I'll want to try and proceed.
Again, thank you very much for the offer. I'm surprised and humbled by...
I'm currently working on the power supply for an old computer monitor (circa 1991). Among the components are 3 diodes that, based on appearance, I think are Zener Diodes. I have been trying to figure out the specs for these diodes, but the markings don't seem to follow the patterns I've seen...
I don't have the monitor in hand yet, so I don't know the wattage for certain. Images of similar monitors I've seen online indicate 86 watts, which I *think* would translate to 0.86 amps at 100v? If that's correct, then we may be in business.
Thanks @Bluejets for offering to help if the monitor...
Thank you all for the advice so far.
@kellys_eye I read a little on auto-transformers via Wikipedia. It sounds like the primary unique attributes of an auto-transformer are a lack of electrical isolation, potentially a smaller size, and possibly multiple taps for outputting different voltages...
I've recently purchased an old japanese computer via online auctions. While I wait for the computer to ship I've started thinking about what possible repairs I'll need to deal with. The computer itself will be receiving a power supply replacement, modifying it to run off USA home power (120v AC...
