    Every multimeter, even the cheapest, gives a reading. How you interpret it is key.

    If you have a manual ranging multimeter, set it to 200 (two hundred) ohms. Touch the black and red probe together. It should read 0.3 or 0.4 ohms. If it is higher than 1.0 ohm, there is something wrong with your multimeter.

    If your multimeter reads "1" or "OL", it means the measurement is outside your chosen range. Don't confuse "1" on the left hand side of this display with 1.0 on the right hand side. The first means out of range and the second means 1.0 unit of your measurement.

    A "1" of the left hand side means the component is > 200 ohms. That is, the bridge rectifier is not shorted.

        If we are reading this correctly, you have a shorted rectifier just as was mentioned before in this thread. I would not power this unit up at all until this part is replaced. Put in a fast blowing fuse of the correct amperage as well.

            I'm going to remove the BR tommorow and search for a new one. The slow blow fuse I got from the Shack had a thin wire with a ball of solder in the middle. Now you got me wondering if I did more damage to the power board using the slow blo.

                HP ZBook 15 G3 Freezes When Picked Up
                by chzuck
                I have an HP ZBook 15 G3 that has developed a problem. If picked up by the lower left hand corner the screen freezes. nothing responds. The only way to shut if down is to hold the power button down. I can restart and it will work fine until it is bumped or picked up on the left lower side. Looking for some trouble shooting ideas, please.
                I have eliminated by battery by disconnecting and running on AC power.

                I picked this TV out of a trash pile. When I plug it in I can hear the relay on the power supply “click” almost immediately, and then 7 seconds later there is another “click” and the power/OPC LEDs start to flash: two pulses on the power LED, one on the OPC LED. I didn't notice any sign of life from the backlight, but more on that below.....

                The service manual () says this is a “DET_10V error: UR10V or A9V is not applied”, but after checking several voltages I believe the power unit is tripping off due to an overload as soon as the backlight tries to come on; this kills...

                Looking for a solderless breadboard that is not trash
                by evilkitty
                I like to get one on mouser/digikey along with a order i plan to place
                i have 2 breadboards one from ebay w/ horrendous contact resistance (to the point on NC)
                and another from ali-express that feels like i am going to break my micro controller putting it into the thing

                any suggestions? (note that i am not spending $50 on a 3m board)

                LG 43UK6300PLB has backlight but no video
                by edugimeno
                Hi! This TV was ready for the trash so I picked it up before it was thrown away

                It's pretty new, so I thought I should give it a try. I plugged it in at home and I was expecting blown backlight as most of the TV's that get to me, but in this case it showed backlight with no video at all (no logo no menu no nothing).

                TV seems internally responsive, drives stdby led red when OFF, responds to remote to turn on and off, but gets no image at all
                Anything common on these sets to start with?

                Thanks!...

                Trash picked this tv from a local business, had a garbage image and would fade to black within second then cut off. It would get shorter and shorter every time.

                Narrowed it down to the right side of the panel by unplugging half the t con
                One side had a great picture the other was black and distorted still.

                Down to the buffer boards… found yet another set of two esd diode arrays. One leg had a 60 ohm short to ground and would get lower the more attempts made to turn the tv on.

                Soldering iron and some chip quick knocked both of them off and...
