Depending on how long you've had your T.V, these problems are usually lamp related.

Open the lamp door and inspect the lamp in the housing to see if it looks bad.

You can purchase a lamp at www.partstore.com The first thing I want you to try is to unplug your TV from the wall for 40 MIN, the reason why is that you night got a small power surge and have some garbage in the TV processor, and that is common with Hitachi. That should reset it all back to normal.

Replace the STK ICs STK329-110s use 120s They are big black ics will have PN# on them.
Mats has them 1-800-628-1118

When was the last time the projection lamp was replaced?The projection lamp on the tv now,has not been replaced like a 1 1/2 or 2 years,tv been on and watches like 4 or 5 hours a day?The tv projection lamp life are over.Require a new projection lamp.

For starters, remove the back cover and turn on the TV. You should see 8 green LEDs on the circuit board.

You may have lost power for the audio amplifiers.

Check the lamp.

Two main things to check, First check R964 for broken or loose solder connection. Then check I901 Part # CZ00868 might be leaky.

The buzzing sound you most likely hear is the ballast trying to fire up the lamp. I would say replace the lamp and yes they can act up at will. If this is the first lamp replacement ever then you are doing good.
