Unplug the power cable and let the tv rest, so to drain power.
This basic reset can fix minor problems.
Try first unplugging for ten minutes, then eventually leave it few hours.

Test also all cables at the back, possibly do first test on tv restarting it with no device attached.

If you still get all blue screen after that then there is a fault.

The lamp or crts, and ballast board are to exclude, the PSU is also unlikely the problem, the TV would have detected the fault and started protect mode.

It is probably a fault concerning main digital control board, or depending on model, DMD board or light engine.

If the TV does not restart and stays in standby, that is because the fault had been detected, and TV is on protect mode.

In that case you may need a technician to test and replace parts.

Try unplugging the TV for a while first.

Flickers after 5min of use. Perfect sound, turns on fine and excellent picture quality when in blue screen menu mode. Why?


This intermittent problem is very difficult to rectify. Just contact the authorised service center for Hitachi at your town. The work is really a skilled one, that a user cannot do it with ease.

A red blue and green line comes across both the top and bottom of my tv . alignment is also off


Sounds like the classic convergence option symptom. If you press menu and scroll to the set up screen see if the auto convergence feature is still listed. If its no longer there the rca repair kit called ITC222 and ITC222A convergence option missing repair kit from www.tvrepairworld.com will usually repair that problem. The kit contains the parts and the CD with repair instructions.

This sound like the standard Mitshubisi PIP board problem. There are two ways to adress this one is to repair the board, this involves replacing surface mounted capacitor and is about %80.00 sucsessful. The other is to simply bypass this board. this option is the way to go, it involves installing two capacitor on the main board and fixes the main pix but kills the Picture in Picture (PIP) I will send off both these repairs to your E-mail
