Hitachi 51g500 screen gone black
Yes worth repairing but not a crt problem. the crt's are powered by a high voltage transformer and sometimes it's caps that goes bad and in turn knocks out the crt's. but they are ok, it's in the high voltage line.

51G500 51 in. Rear Projection HDTV-Ready Television went black white why?
It does not have a "color" tube, the model here appears to be a set with 3 picture tubes---do yourself a favor and unplug it and a box if used or a receiver if in the line--wait a bit and power back to see if the units connected will reboot.
Also remember to check all the inputs to see if any have color: if using the cable wire direct to a set hook a DVD etc to one of the rear audio video inputs to see if same problem there.
Let me know what you find--I answer about 400 questions here each week but try hard to help anyone who responds or needs more help.

I have a hitachi 51g500a convergence problem i
you can and should use two of the same; the 150 and 110 are identical except the 150 is a higher current device.
I usually replace both with the 150; be sure to remove all the old white heat sink compound and apply fresh as well as checking all the low value resistors around the two chips.
Let me know if you need help or have questions.

The power is not coming on, and when it does it
Bypassing the V-Chip Lock
After you set the lock, you need your passcode to view
a V-Chip locked program, view the locked TV, cancel
the lock, or enter the V-Chip Lock menus.
If you forget your passcode, you can view the locked
TV without entering your passcode.This is done by
pressing the number 9 and QV buttons on the TV
remote control at the same time, when your passcode
is requested.This process temporarily unlocks the TV.
When entering the V-Chip Lock menu, this process
deletes your old passcode and prompts you to enter a
new passcode.Press HOME to exit the menu.

Hitachi 51G500A Convergence Problem
Hi, 110`s & 150`s are both replaced by stk 392-120`s. which run waaay cooler because the 120``s are rated at 4 amps while the 110`s and 150`s are 3 amp devices , the real key is to make absolutely certain you are not buying generics (which are everywhere on the internet), there should
be NO black print on the back side and a 4 digit code (not 5) on the front, top right corner, the originals or OEM`s are never $8.99, usually run about $12-15 and are made by Sanyo but the word sanyo will NOT be on the IC`s , so go by the info above, be sure to check for burnt resistors next to the heatsinks as well, good luck, video-tek
