    I bet that thing is not worth fixing.

    But we'd like to see the inside, see what 'noname' caps it has!

      funny you are the only one who caught on!
      i will open it up and post the insides.
      problem was 4 22@16 sm caps on the old rage 2c in the system.
      monitor is fine.but the symptom looked so much like a projection tv with bad stk's i just had to do it.
      the monitor is a noname 1440x900. sometimes they are fussy to get set up.

          ITE IT8390 (IT8390E-256) programmer "ITE Download Board 4" user manual + firmware, flashing ITE ECs on the cheap
          by H34TO
          Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...

          When your mom is complaining about her new cheap lights
          by evilkitty
          My Mom bought some cheap motion sensor lights on wish... then complains about about batteries and this thing chews though them, well it uses 4 AAA batteries and a pack of rechargeable ones is about 13 USD

          well since it uses 4 AAA and rechargeable are 1.2v and non-recharge at 1.5 this thing must work with 4.8-6v, I'll shove a USB cable on it, infant i will use a broken phone charge cable... dam this thing uses 430 mA and they made it battery powered...


          lets ignore the fact that i thought the board fit both ways... and the wire color is reversed going to the board...

          Recommend a decent Multimeter on the cheap
          by aaronkatrini
          Hi all,

          I was looking to upgrade my main multimeter (Asita MD591) with something that has more features. I'll use it mostly for board diagnostic and diy repairs. I've been eyeing out many of those multi-function ones from Aliexpress but can't seem to make my mind up. Here are the features that I'm looking after:

          - Autorange
          - DC volts up to 30V
          - Accurate Resistance
          - Diode test (Beep mode)
          - Frequency up to 200MHz
          - Capacitanze up to 5000uF
          - as cheap as possible

          Other functions are not needed but those which are needed...

          Schematic for Sonifex Redbox RB-DHD6 - Headphone Distribution Amplifiers
          by ElkoZH
          Hi everyone

          i have to replace an SMD ceramic capacitor on my Sonifex Redbox RB-DHD6 (Headphone Distribution Amplifiers) that is visibly burnt. I've been looking for a technical schematic for weeks, unfortunately without success. Can anybody help me further?
          Thank you in advance for your help

          The Cheap Duo - Two SiS machines
          by Dan81
          Just as the title states. Two cheap SiS machines, surprisingly stable.

          What I will tackle in the near future (the build will be slightly postponed due to slight stomach issues - am still recovering and my physical power (sorry if it sounds weird,English isn't quite my primary language) isn't the best at the moment. Especially with the diet I have to take at the moment.) are two SiS based machines.

          The first one is a IPC rebranded Mitac 7521T. Why did I feel the need to tackle this machine? Well, just look at the specs:

          CPU - P3 1100MHz Coppermine...
