          Have you checked the power supply voltages to see if one of them is taking a while to come up to full voltage?

            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...

            Panasonic SA-MAX770PU SMPSU board fault....
            by Rictech
            Hello everyone. 😀

            As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
            Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

            Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
            This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
            There are no devices that have exploded or otherwise show signs...

            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....

            ESR meter came to the rescue again today with a PLC I/O card fault
            by sam_sam_sam
            I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
            I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not

            One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference...
