Why does my vp50 hdtv20a turns on for about five minutes and then turns itself off
sounds like you have a bad capacitor(s). my TV did the same thing, so I removed the back of the TV and looked at them and noticed (9) of them were bulged at the top ( should look flat). I am no electrician by any means but was able to replace them with a slightly higher voltage myself for around $45 instead of someone servicing it for $400
Sound but no picture
this happened to me about a week ago. It was my cable box. If you have a cable box,unplug it from the electrical socket Wait about 30 seconds and plug it back in. give the box time to gather all info and then retry the tv.
Power suppy
Is this a question or what you call your suppy?
Hard reset
Unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This must make it a hard reset. If you wish to do a system reset, you have to enter its service mode to do this. If you wish to get more details about this, check the site linked here.

Main power fuse location
The main power supply board houses the main fuse. Beware, some sets have multiple fuses on the main board. Besides a fuse, some sets have input filters for incoming power. These filters are before the main fuses, so if you have one, verify that you are getting power out of the filter
Vp50hdtv20a does not turn on,
it is possible the power supply board that was replaced was a refurbished board. you also may want to think about underlying issues with the sustainer boards causing the power supply board to fail.
My tv cuts off after 5 minutes
Could be the power supply overheating and going into protection mode. If it is under warranty use it. If not then you could take it apart (this will void warranty) and check for swolen or leaking capacitors on the power supply.
