Thanks. How do you unlock the code? (BTW, I'm new to FixYa and saw your posting right after I posted my problem. So am not sure if you're answering mine or not.)

HITACHI PROJECTION TV HAS WAVEY LINES ON IT THEN SCREAN GOES BLACK


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board
power%281%29.jpg2_23_2012_11_31_16_am.png

After replacing blown capacitors...it should work again.

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps

Screan has no picture


i am not familiar with this television, but i can take a guess, it may have a snooze timer, which will make it dimm after a certain amount of time inactive. you could increase this time in settings, found on your remote.
hope it helps.

Delayed video, audio comes first


It's normal for Sony TVs to have a delay in the video. The screen stays blanked until the circuitry in the set has decided that the picture tube is operating correctly. The screen can remain blanked due to a number of causes. Bad solder connections or components in the vertical output stage are common. Also, Sony sets automatically adjust some tube voltages. If the tube has aged enough or component values in the set have changed and the adjustments don't keep the values in the correct range, the screen will blank out. Intermittent components or connections in the set's video stages or source switching can cause screen blanking. Unfortunately, this is one of the tougher Sony problems to troubleshoot. It usually requires the schematic and an oscilloscope to track down.

I have no idea so if you can help thanks


The board on the left will have a series of small aluminum heatsinks with black ICs attached to them one of them will be the vertical output IC with about 7 pins on it. try resoldering those ICs and you should get the picture back as the vertical ICs will make the tubes cut off. The vertical IC should be marked on the board but solder all the ICs mounted to heat sinks on that board to be safe.
