[QUOTE="RustySpoons, post: 1054796, member: 412012"] PSU caps "Look" fine to me, but if they look good doesn't mean they are good, however if they are domed then they are definitely bad. There are other bits of the circuit that will provide different voltages, the main thing is to see if all the voltages are present or are not too low/high. Look at the ribbon cable on the PSU that is going to the board, hopefully they have silkscreened the voltages on there, hard to see in the pics. Put the multimeter on to Voltage mode and keep one probe on the negative and put the other lead on the other terminals on that ribbon one by one and check, write these down. If you don't get far in any of this i'd be happy to take a look at the box for you and repair the PSU or swap nand flash/eeprom if possible. Solid yellow is usually glue they use to stop the cap moving or resonating. [/QUOTE]
