    Re: Instruments/tools needed for TV repair

    I'm not that good, but I'm getting better and better. Budm it's awesome for sure and tom66 and all others around here also.
    I still have issues with a Vizio VO42L, LG70LG and an Asus MK241H monitor though. I think that Samsung 46A530 finally will be fixed, because the 52" mainboard mod didn't work out as planned. This weekend I'm picking up another one with broken screen for $50.
    I still have a Philips, which is completely dead.
    Finally I have put together budm's short circuit tester. It came out very nice and compact. One steel box(the ones which goes into the wall), steel cover with switch and wall outlet cut out, wall switch and a wall outlet. The bulb is a plug in style and plugs in in an outlet, the other outlet is for the testing device. One of the side bridges from the outlet I have separated. A TV power cord and one of those clamps with nut on the side of the box and it's all compact and nice.
    I will take pictures when I'm home.
    One of the monitors (thanks to budm for helping repair it) is set up on one of the benches(IKEA $40 kitchen table ), now I(we) have to repair that Asus to be able to install it on the real workbench. This way I will have two separate work places with two monitors. I can work on two TVs now. Need more help from budm

        That looks great, you will be so happy when you are trying to find out if you still have short circuits or, when it is bad it will light up bright right away. You can prove that by putting a jumper across the filter cap to simulate dead short so you have some idea what it looks like, then try it with working TV or monitor, you will see how the lamp react.
        Do you still have that set with the shorted out MOSFET's that you replace twice? You should alo haev some 150Watts and 200 Watts for testing some big TV also.
        Nice job.

          I would like to purchase a cordless screwdriver which is using Lithium-ion batteries.
          I try to keep it under $100.
          Which one do you recommend?

            Dumpster diving outside my internship work place (well, more like "Throw this stuff out Tom - anything you see that you like, you can keep.")

            Got a cordless black and decker screwdriver with dead NiCds (0V - completely shorted cells.) Just zapped 'em on my 35V supply a few times, charged them with my RC aircraft battery charger (charges anything from lead acid, ni-cd/ni-mh to li-poly), and got them back to life.

            More serious recommendations:
            - It doesn't really save you much time using one as you spend more time trying to line up the bit on the screw, especially as the device is physically larger.
            - Avoid the cheap supermarket/budget brands with 2.4V NiCd batteries. They only give 20-30 minutes operation - or about 2-3 TVs. Inconvenient to run out of charge in the middle of a repair job.
            - Also avoid the black and decker ones as they suffer from dead NiCd batteries as outlined above (trick doesn't always work and needs to be done every so often to keep the cells from shorting.)

              I've always had a DeWALT small hand drill. Very tough and long lasting.

              But, recessed screws, as stated above, are a pain sometimes but in my opinion, beats turning a screwdriver 500 times lol
