    Dmtech dml-4126

    HI all have a strange problem with this 26" lcd ,
    when first start up all works fine all inputs work, menu's work and remote all fine until you turn it off then it stays in standby.

    Tried a new PSU but still the same leave it unplugged for a couple of hours and it will work again but only till you turn it off.

    Before i start delving into tests just wondered if anyone had come across this with one of these before or have any suggestions .

    Will do pics and post them later

      KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen.

      KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help.

      Dell ATX PSU won’t start, but forcing it works fine?
      by CapLeaker
      Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.

      Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing. O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

      RTX3090 working fine but fans not spinning
      by emil_t
      Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....

      Car Headunit (Chinese?) No Sound / Audio
      by Bloopeta
      Just bought a car that has a stereo in, thats bluetooth etc, and powers on fine and all functions seem to work, BUT there is no audio/sound.
      I have tried another unit in the car that works fine, so know it definitely a problem with this unit.

      I know it just cheap rubbish, probably of chinese origin, but its really bugging me just throwing it away and replacing it 🙈🤣

      I know zero about things like this, ans its probably unfixable, or more trouble than its worth, but just wondered if there was anything to check, as what could lead to an easy-ish fix? Havnt opened...

      TD Systems K50DLP8F works fine on 1 HDMI, bad on others
      by edugimeno
      I have this TV set that I spent a long time fixing it.
      I finally found a shorted SMD capacitor near the plug from the PS at the main board. It was shorting one of the main voltages (can't remember which one)
      I removed that capacitor, and as it has another one in parallel, I left it with only one, checked it and it seemed to work fine. The solder near that capacitor was really delicate as I pulled apart one trace so I prefered to not mess much with it after I had to air solder one small thread of copper

      I didn't use that TV much at that time. Now that I'm using it,...
