Mine has white screen brightness doesn't work and also no sound. This is after a recap so its not the caps. Unit did work fine for a few hours now it does this.

oh shit i want one !! i just got 3 compaq portable recently ( 1 compaq portable 1 , and two compaq portable 2 ) i manage to bring back to life one of the two compaq portable 2 , still have the keyboard to restore , but i"m stuck with only 640k ram , no ram upgrade cards in mine sadly

je cherche la valeur de R7 derrière les deux condensateurs de 330uF par avance merci

Where'd you get the part, and is it possible you can send the link? Thanks!

This looks smaller than the Pico ZX. It's fantastic that it even has the C64 function keys. Is this project on PCBWay? Is there a way to purchase a completed unit?

Great video! I just bought a modded system loaded with games but none of the games except Atari/nes will play can you possible help me out I think I got scammed on my buy any advise would help it has a 3tb with the clock capacitor removed

Does this fully dim/off or just dimmer than bright?

I gotta do this on a 10Nes chip because the leg I need for regionality is broken

I had this problem and my solution was to not push the cartridge fully into the machine.

One game gear Im trying to fix the sound board dial is so rusted maybe that’s the problem why there’s no sound, another unit Im trying to fix is missing a piece, the one that looks like a coil with six feet in your soundboard. Both dont have any sound, maybe I’ll change the rusted dial with the other good one

You just saved my bacon. Had same issues with finding a schematic and was pleased to follow along and triple check my issues. Exact same issue, zener open and transistor exploded.

I want one and hope to build something similar soon can I contact you somehow I'm also in Australia (Brisbane)

Something you can do to test CRT monitors is shine a bright UV (black light) lamp at the front for a few minutes, then look at the CRT in the dark. It will be illuminated and you can see the burn in more clearly or see if there is any hidden burn that sometimes does not show.

silvestron is my uncle🐕💖😃

I recently managed to get a T4400SXP, that's the one with a gas plasma screen. It was sold as "for parts", but I managed to fully revive it! Ended up testing and replacing most of the capacitors, plus a fuse on the plasma panel power supply board. Also had to patch up a few traces on the power board + motherboard. Really happy with the result, the plasma panel appears to be in very good condition, it's bright and no observable burn-in. I also got the Desk Station IV docking station with the thing, so that's a nice plus!

Whats the name.of the tool you used to check the frecuency osilation (the one that shows the graph)

Just discovered your channel. Love your content. My first computer was a C64 and seeing the care and love you have for them just makes me smile. Also really appreciate that you don’t bury your videos in awful music and use it sparingly and appropriately. So much overstimulation on YT these days and this type of quiet detailed content is a diamond in the rough.

What a fantastic idea. Great execution. Thanks for sharing this

Enjoyed the video. Thanks for putting this up.

Hi! question regarding a 1541... When I turn on the drive, there are not lights at all, but I can hear the motor and see the (don't know its name) circular thing which goes in the middle of the diskette spinning around... do you have any idea about what could be the problem? many thanks in advance and for your time

36:07 heh. Grab my joystick. 😜

Great video. I especially enjoyed the scope work and the explanations.

Nice video! I feel your pain with forgetting to switch sources, forget ground, etc 😂. Nice that the replacement ram worked by grounding the extra line. Glad to see it working again!

Quick and easy fix. That crystal was nasty 🤮

Your comment on Soder-Wick inspired me to look this up: Up until the mid 1800s British English pronounced 'solder' with the L silent. North Americans kept the old pronunciation, while the rest of the empire evolved.

Good thing they don't use those horrible NiCd batteries that leak all over the place.

Awesome!!!

I have a game gear with exactly the same problem. Do you fix them for people?

Thank you so much for this video. Just finished comp modding a SMS2 thanks to your video. I did put in both audio channels for dual mono. Put in a 100Ohm resistor and 470uF capacitor between the video wire and the RCA socket. Took off the underside bodge wire as well.

Those scorch marks could be chemical burn from cap leakage? Also, you could use the good board to check meter values and compare.

New Sub; Detroit, Michigan, US That is AWESOME! I've Wanted this thing for Decades, I dont remember what Magazine I saw it in, 80s/90s, but I remember seeing this in an Article along-side the SEGA/IBM 386 PC. I have Never seen one of these before, but I have always wanted to try one out for some reason LOL

Even better are the switching mode 7805 equivalents so you no longer need those chonky heat sinks.

Hope you work it out. Thank you for fixing my SEGA a year or so ago. FYI - those Segas are notorius for cracked solder joints on the carport.

9V across the fuse? Guessing it's blown then 🙂

Put it into H!

Would this need any modification to work in a Compaq Armada 7700 series? They also use the Citizen W1D

The original batteries had RCA labels

I also want to convert USA version to European power supply ( from 120 to 230v 50hz). Can I use the same spec caps as you for 230v?

Beautiful! I have a question. I didn't realize there was a 4700c. I was thinking about buying the 4700sx, but then I also saw a 4700ct. The main reason I am looking at the first two is of course the orange gas plasma display. I couldn't find much about the CT. Do you happen to know if it has the orange gas plasma display? Thanks for reading this.

Mine after greasing up the motor on the CD mech works, but strangely when powered on spins anticlockwise and takes about 5 mins to warm up before it wil read a disc (spinning it the correct way, clockwise). Caps seem ok on visual inspection. any ideas why it needs to "warm up" and why the motor spins anticlockwise slowly when powered on by not reading a disc?

Excellent video. I have two of these machines. One of them fixed up for now (recapped systemboard, inverter and remaining screen caps + cf/ide 512mb CF). The other one is still to be fxed (as soon as you connect it to power, it will power on regardless of how the power-switch is on or off). They are quite nice machines. Not the fastest ones around, but otherwise quite cool.

Hello. That is a great modification, one that should have been done from factory. Please execuse my lack of knowledge. I'm trying to have the nVidia Shield TV (same as the one in this video) as the main headunit in my car. I have a broken Shield power brick, so I bought a 12v to 19v 3amp buck converter. I snipped the wire from the power brick, connected it to the output of the buck converter and plugged it in. The nVidia logo showed up and my happiness was short lived. As the screen turned off. Any ideas what could I be doing wrong? I measured the output of the buck converter to be 19.16v Appreciate any help.

I've had my Citizen W1D open no less than 50 times since replacing the belt trying to get it to work. You'll probably be getting a new order soon hahaha

Always so satisfying

Nick where can you buy that extended battery rom pack? That is really handy..!

Great video! I've done the HSIO screen a few times now, and it's a very similar process. Looks good!

Underrated video

Great work..!! I wish i couldt fix those things like you do..

Awesome work! I've got around ten or so old laptops I'm going through reviving. Currently working on a Compaq LTE Elite 4/75CX that's almost untouched. Waiting for a belt for the Citizen W1D. The drive looks brand new other than the deteriorated belt. Not a spec of dust.

I was watching a different video then it skip to this one and I looked up and was just shocked and was like what have you done 😂. Then I realise that you were fixing that Massacre of a mod. Good work at fixing it.
