Question about Hitachi 42HDF52 Television
Did you by anychance take that tv of yours to the hampden, ME dump
Posted on Nov 29, 2009
The most likely the TV has a power supply related problem. It maybe a blown fuse inside the TV.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

It appears like the 5VDC is low from the power supply adapter. This voltage becomes low due to defective capacitors inside the power supply.
