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.

Colour loss


Try a reset to this set and check. If it do not help you, contact any service technician. There are two types of reset to TVs. The first is simple to do; a Hard Reset; and the other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

What is the Remote Model for TOSHIBA Colour TV Model 2168TIV


In my opinion, you should not have to give them the remote number, but you can look this up by contacting the customer service website of Toshiba, giving them the model number of your tv..and explaining your situation...also check eBAY for remotes.

RCA F31317 lost blue in picture.


this symptom is characterised by the loss of one or two primary colours. this symptom can be classified into three cases: 1) loss of red colour, 2) loss of colour blue,3) loss of green color. this symptom may be caused by a trouble in the colour demodulator, in the color amplifier or in the colour subtraction amplifier circuit. in your case loss of blue colour. this is a very complicated problem that you need some special test equipment like oscilloscope and color pattern generator in order to trace the signal. tune the receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the chroma signal. observe the signal process with an oscilloscope. if the color signal is not present use a VOM to locate the defective component in any of the above circuits. check the transistors and the resistors in the collector circuit. good luck!

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
