Does the raster have horizontal lines anywhere on
screen?I am not sure about replacing ballast.I have access to hitachi
and can get the info.Is the raster all white or a bluish tint?If you want i can get you the symptom and problem fix.

If i understand the lights have to be turned off
to see raster?If you ordered the ballast and screen is not
bright now than it's possible the the ballast is faulty.
After installing ballast and you still have no video reply and notify me.There are fixes for no video.Good luck.

Sorry to hear that the set still has the no video.
Do you have any troubleshooting experience?And a DMM.
If you do and want to check the possible causes i can
get you the symptom and causes reports.The one thing when
replacing the lamp you should always wear latex gloves
the oil from your skin can shorten life of lamp.

If you can't check voltage you can't troubleshoot it.
What you could do is check all connectors around the lamp housing
and if you removed the lamp housing especially.It sometimes can happen.
Good Luck

optic block (LE) going bad,just want ot pass this on
The block isn't cheap and disasembly is not easy.
