Re: 32" Toshiba television Mod. 3357DB
If im not mistaking I remember the toshiba 32" to have an on screen alighnment in the sevice menu.. and I would not recomend that anyone without the proper manual and tools to fool with these adj as I've seen in the past that a set had to be completely redone even the tuner alighnments after someone went in and tryed to adj the set., Now the green tinge you speak of is the CRT getting weak The best way to ajust this would be to see if on the picture tube pc board on the end of the Picture tube if it has any little control on it ? if it does look for the green drive and put on a b&w Picture. slowlty turn down the green drive control untill the pic look almost B&W and you probably wont be able to get perfact grey scale as the crt is weak . If theres no controls on the crt pcb then your gonna need a service alighnment manual and adj the green drive that way. Good Luck
Phew,nearly threw out what thas turned out to be a perfectly good telly as it was showing excess green and "common wisdom" was that the tube was "knackered",not so as i've managed to piece together from the "net". BE CAREFUL WHAT YOU PRESS. Go into your t.v service menu with an (old) B&W film playing and adjust your tvs' R,G.B cut-offs (this will work with any reasonably newish tv) until the picture becomes grey/b&w looking (again?), your eyes are reasonably good registering this,I have just given my old jvc 32/50hz a new lease of life.P.S If your telly was as green as mine was then I don't suppose you will care to note your original RGB drive/cut off settings anyway..!!

Hi: You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.
Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.
By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
You may have inadvertantly loosened a cable connection to the DMD or logic board... You might be able to shut it down, unplug the unit and remove the lamp.. With the lamp out take a good flashlight and shine it into the lamp housing area inside the Tv and see if you have any wire obstructions that you could have contacted with the edge of the housing as you were removing or inserting the lamp...
If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.
My first inclination would be to check the picture tube, especially if the set is over 7 years old. If it is not that, then anything from bad solder connections to capacitors or a defective IC could be the cause. If it's over 10 years old, replace it. No use flogging a dead horse.
With the set being 12 years old, I'm sure the picture tube is near the end of its useful life. You probably have a defective semiconductor, either an IC or transistor that has gone up giving you no color, but with the green picture, it is not likely worth repair.
