Question about Hitachi Televison & Video
Since you have audio means you have a signal. Depending on how it’s hook up in back maybe a video cable. Check all cords make sure they fit snug

The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.
In short, you need a experianced tech to troubleshoot this.

Almost for certain your power supply board is bad, Can be repaired at the component level only if you have some electronics savy! Good Luck!

Had the same problem myself. Took some doing but I managed to find a service bulletin that I downloaded. The problem is with the siene module and all you need to do is unplug connector JP63A from the main board and your TV will work again.
Take the back off the TV (there are a lot of screws) and look on the left hand side of the main circuit board that is mounted in the center of the TV. You will see a small white connector that is labelled JP63A, simply unplug it. Plug the TV back in and let it reboot. That's it, should be able to watch immediately.

SOURCE: Black out?!?!?
I turned on my 55HDS69 a week ago and WAAH-BOOM, No more picture but the sound was fine. The resolution underway at a local repair shop is to replace the upper & lower buffers. The TV is 2 yrs and nine months old. I did not buy the extended warranty as I expected a $3000+ TV to last longer than 3 years especially since my house is like a climate controlled class 40 clean room and teh TV is not over used. The parts are ~$225, The labor is ~$225. Hitcahi would have sent the parts for free had I been within the 2-year window (1 yr regular warranty + 1 yr grace period). It was absolutely silly of me to think HITACHI would do the right thing and send me parts at 2 yrs and 9 months (sarcasm). I can tell you one thing......There is NFW I will ever buy a Hitachi product again and that includes anything even affiliated with Hitachi (inc. imbedded electronics). I will steer every person on the planet away from them in the future. My original plan was to ship the TV to the Hitachi CEO to make a point but the Hitachi folks don't deserve that kind of respect (Unless it blows out again) :(
