Power issue


Check all the other pico fuses on the board. One or more may also be blown.

Won't power on


Linda,
A VERY common problem with this unit is a small blue disc cap C707 (102 @ 2kv) tucked in front of the horizontal output transistor. It usually has a small pin hole burned in it when it goes out. The cap is actaully part of the scan circuit and it changes in value over time and becomes unstable then opens, usually taking with it E994 a small pico fuse.
I wouldn't spray too much duster in there for all the dust it will create. You'll be dusting the house for days. But it won't hurt using a can of duster or air to blow it out if you want...

Hitachi TV will not turn on.


If have already unplugged and waited for atleast 15min. and still no success. Then only if you are Electronicly inclined. Check to see if you get dead completely or you get an indicator light momentarly. Which these are two different symptoms. first dead no indicator. check R931,E994,Q777. Then if indicator light comes on and goes off, check E994 which is fuse opening, C707-1000pf 2kv cap, also check D915, I601, IK04, and 05
