Question about Televison & Video
I cannot understand what you exactly mean when you say that you "can almost see the menu".
If the picture is very dim or dark, and you can only barely see the the on screen menu, then the culprit may be the lamp, the ballast , the optical group, and digital board (eg faulty white balance circuit).
This fault is quite uncommon, and the TV will need to be tested by a technician.
The first part to check is the lamp. Even if the lamp is turned on, in rare occasions you may have a defective lamp, and that may cause the problem.
Testing the lamp with a replacement is the first thing that will be probably done at a workshop, but it may not be convenient from user point of view. The lamp is expensive, and it is not necessarily the problem.
The high voltage board that supplies power to the lamp must be tested. This is called ballast board or lamp power board, and it is connected directly to the lamp.
If lamp and ballast are OK, the next part to test is the optical group and light engine. This is one of the most expensive parts on TV, and it is likely causing the problem, since lamp or ballast causing the problem is quite unlikely.
Making the point of the situation this looks like an uncommon fault that is difficult to diagnose and repair.
As a first thing I suggest calling Hitachi customer care, ringing the number listed on the owners manual. If they offer an affordable repair, better to get a technician to work on TV.

Hi,It sounds like it could be the ballast.The ballast is the board that powers the lamp.The ballast is the one that lets you know if lamp is not responding or if it's not able to power the lamp.This is the most common failure it's symptoms are exactly like the lamp it will,flicker,not turn on at all,get lamp indicator,usually you will hear clicking or attempts to light up the lamp.The ballast is a simple fix and cost less than the price of the lamp,it's usually sitted right next to the lamp.I have a video for a samsung on how to replace it ,it's the same procedure: http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php Found the one you need here:http://greenchip.shopjimmy.com/catalog/product/view/id/169785/s/hitachi-ballast-ha01331/ Have a bless one!
