I have a Mitsubishi VS-60621 (VZ4 chassis) with intermittent shutdown. I have been to the customer's home twice ( I resoldered a multitude of connections the first time and replaced capacitors C912 and C914 in the power supply the second time). The set may run for a week without shutting down or it may act up daily. the problem only occurs when the set is warm. I had to pull the set in the shop but have not yet been able to spend any time with it as I have been a constant roadshow, however, I will be in shop tomorrow and would appreciate some feedback if someone has experience on these as I am working WITHOUT a service manual. I have not personally seen the shutdown. Wish I could provide more and I will be monitoring the B+ tomorrow. Anyone have some ideas for me?
