Try soldering the vertical IC, & check the electrolytic
capacitors around the IC. This may be why it shuts
down! Check soldering in the power supply also!

If anyone would be so kind as to lend a hand. I have a Hitachi 27CX5B that
randomly powers down. The set will not restart for 30 to 40 mins after
power off.

Any Ideas?
