Re: I paid 9.95 for assistance and did not get a responce...
From your description it sounds like G2 voltage on the green picture tube is too high. Are you confident about adjusting it yourself? There are high voltages in places which can kill. I will not take any responsibility of you getting an electric shock so I suggest calling in a qualified TV technician.
Any TV technician should be able adjust this voltage and it should not take long to do it unless the cases are hard to remove and hard to access the flyback transformer where the G2 (screen) adjustment is located.
Otherwise it may be a faulty green picture tube and this is expensive as you need to get the tube replaced.

May have burned CRT(s), (if you are not talking about convergence.) Burned CRT shows when that CRT (R,G,orB), does not show in an area of the screen where it should. Check bright white color = full R, G, and B CRT brightness. Gray = mid RGB brightness. Yellow = R+G(no B), Blue-green = B+G, no R, etc.
Let me know the symptom in detail. Green bulb (CRT) gives high bright light and tv goes to standby? Do you see few horizontal (retrace) lines while this happens? If yes, you need to replace Green bulb (CRT) of your tv. Please mention exact model number of tv to guide you further. and what IC chip you replaced in tv?
I have the same problem with a HT250, red power light on back of projector will not come on. But if you leave the projector plugged in and power switch on it will light after some time and the projector works as normal. Any suggestion please email firstname.lastname@example.org
its very possible that the blue CRT is horting the set out. Heres how you can test it. Remove the speaker grille and access panel behind the grille and you will see the crts. remove the blue crt circuit board from the end of the blue crt and make sure it isnt touching anything then try powering up the set if it doesnt shut down then you have found the problem and you will need a new crt. or you can switch the blue circuit with the green and try it iwth the blue on green and the green on the blue then if the screen turns green before shutting down you will know that its a problem in the blue drive circuit and not the crt. lety me know if you need further assistance.
