I have an NEC plasmasync 42MP3 - PX-42VM3G which appears to power up with all voltages I can identify OK, but no display at all. The PSU makes a low level hissing noise as if its under stress. Reading some other posts on similar models, I've seen capacitors mentioned, presumably going low value.

Does anybody have any experience of this fault symptom or info on the PSU (42NH-PDP-4) please?
