    Hello there! Are you still available for electronic troubleshooting assistance or have your priorities shifted in life these days?

  • Re: Toshiba Satellite L300 Wont work with charger

    PLease describe the behavior of the charger. Did charger "shut" down when attempted to use with the notebook? So on. If this is in case, there is a bad shorted IC somewhere near by. I had to locate MOSFET transistor with ohmmeter and replace with compatible one. Be aware in these design they always parallel with another at least 2 or three so pick one and desolder it. Chances you get right one or wrong one.

  • Re: Challenge! Can you help me identify these parts?

    This link to replacement capacitor is not what you want due to gerneral purpose term.

    And this is not a Tantalum and OP wanted 470uF not 220, please read carefully.
    This is actually polymer SMD capacitor due to low profile than tantalum. Pick up a junk notebook and salvage one.

  • VFD or electronic drive for motor.

    I'm not famillar with these design to drive small motor like size of a sewing motor either AC or DC. Roughly 1/10 hp. Also reversing (switch), variable speed via foot pedal. I have access to high current IGT (spelling?) transistors off the old junk plasma TVs. These comes in paralleled transistors instead of one module so easy to adapt.

    This is to drive a watchmaker's lathe as this came without one.

    Yes, I have many hobbies, seriously.

  • Re: Optical drive won't read discs

    Still LG. My drives are still living for few years. Contrast to previous drives I had like philips chassis, Asus, LiteOn had half-life of a year or so.

    How old are your LG that died? By the way don't even try to fix anything, Optical drives are so cheap not the effort to fix, except for parts to use in other projects.

  • Re: Dell Precision WorkStations 670

    Still based on P4 core. Not great deal. I hope you did not invest too much on it.

    I bought up a C2D Optiplex 745 complete (2GB, 80GB swapped for 320GB from my parts pile) cpu is 2.1GHz but is much farther ahead than a fastest P4 even Xeon. This was for my coworker's old 2.4GHz P4 replacement. Went well and much better. Cost me 170.

  • Re: Topuchpad vs trackpoint

    ratdude747, check gamer mouse. Laser and many buttons is great combo. I do not want red optical mice as these pointer tend to mistrack. Just enough to annoy. With laser mouse I have no issues with these and better tracking except for very rarely jump but that is not that often.

  • Re: Dell Precision WorkStations 670

    CPU is either L or E series.

    Also there are multiples of 3.4GHz xeons. This is reason why I do not go by the speed. I was asking about the actual number off the CPU's top.

  • Re: Dell Precision WorkStations 670

    Post the type of Xeon CPU please.

    PS, if it based on P4 core, it is not good deal, If xeon is based on core 2 CPU then that's very good deal, hence the reason for asking for CPU Xeon type.

    Slaps my forehead. Oooh. Okay, that sounds like bios eeprom is corrupt otherwise board is junk.

  • Re: For the CRT monitor freaks - highest resolution you ran on your tube?

    Per, Redo the tests with newer LCD late 2010 and 2011 to confirm if you can borrow them.

  • Re: For the CRT monitor freaks - highest resolution you ran on your tube?

    Old article (2 years ago!). Technology changes all the time at blurringly fast. Case in point: I bought a 19" (931C) in 2007 and panel was too slow and saw heavy smearing during fast scrolling. Bought new one last year 2010 LED LCD Samsung PX2370. No smearing. Things do improve.

    Go to forums that is specific to the gaming and monitors and see what have changed. And general advices I put out still apply. The problem is not all monitor makers have clear info on disabling the processing even...

    Re: ACPI Controller

    Kiddznet,

    You won't and end up in frustration. What I suggest is open up the hardware property then device manager. Open the item that has yellow icon (!) that has ACPI item and go to: details tab, write down the first string, ignore the rest of gibberish. Google with this to find out what it is for, then download driver from the maker's site for that computer. Direct computer's (!) to reinstall driver from specified folder & detect downloaded driver. This that I did several times to several computers.

    Cheers, Wizard

  • Re: For the CRT monitor freaks - highest resolution you ran on your tube?

    There are many good LCD monitors in sub 5ms to 10ms. And don't be just passive, demand loudly to the LCD monitor makers to fix the lag in the scaler board. Going by native resolution and HDMI/DVI bypasses the scaling delays.
    Also to anyone who have decent monitor and TV like samsung, change name for the input to "game" will shut down the scaling and video processing to give you the minimum delay. Other compititors may have this feature but that takes some digging to find out.

    Re: ACPI Controller

    chipquik is WORTH in money alone, good profit making. Saved so much effort many times. Just 2mm to 3mm chunk is enough to do a typical IC up to 100 pins.

  • Re: Pcb Markings - what component is ep ?

    The resistors? The marking on these SMD itself says resistance value.

    The other compoenents that is capacitors and protective devices like this should be open circuit. For zener it acts like diode when checked both ways.

    That all, cheers, Wizard

  • Re: RCA FKR468WR repair/restoration

    These usually don't have bad caps, just bad joints on all heavy components like large resistors, flyback etc. Cannot resolder, have to take each component out and scrape the tinned part clean with razor and resolder back in. Be care with the PCB it is not forgiviing to too much heat.

    These are for anti-static protector like the VR in other devices. They short the spikes to ground, all of them are grounded. Good thing to do.

    Like others says, go into set up bios settings and reset as instructed.
