there are 2 tuners in a rear projection tv. maybe the main tuner is faulty or the tuner's associated circuit has problem. if there is no signal these tv are programmed to turn the power off/stand by.
The main board/switch is worn to the point it will not work anymore after a while, I been in the business for years, These are wonderful TV's, yes there are replacement parts but a quick fix your looking for here will be unsuccessful this is the reason I am providing my advice and take a chance on the rating your going to give me. Try www.ebay.com look for people that is saling parts for these TV's.
That is a VZ3 chassis, similar to Mitsubishi models Ts-4545, Ts-5045, Ts-5545, Vs-4543, Vs-4544, Vs-5043, Vs-5044, Vs-5047, Vs-6043, Vs-6047 and has common failures in the vertical circuit, specifically vert Ic401 which is a La7845 which is usually caused by defective C402 100uf 50v and/or open 1.2 ohm 2 watt R510 next to FBT.
If not that check C268 off Q215 on signal board 22mf/50v and Ic200 on signal module Cxa2025s. However the vertical failure is more likely.

You could have a problem in the sweep or main power supply, Bad capacitors on the DM module, they will be all grouped together and have swollen tops, Coolent fluid leaking out of one of the CRT's. If you have no electronic or solid state repair experience, please get a pro to assist you in this repair. Good Luck
