    another thing that thomson is notorius for pending on the model of the board that would help me a bunch but they are notorius for there on board tuner needing to be unsoldered and check all grounds and resolder i use to have to use a jewelers magnifying glass to see but resolder all the ground points under the tuner shield and that could do it for you if you could please send me the number of the motherboard like ctc162 or ???? thanks

    also i should have told im sorry i forgot but you have to float one end of the diode to test it on back of the crt socket board in case you are not familiar with float you have to remove one end of each diode either end cathode or anode then test it i hope this helped

MY TV MONITOR COLOUR IS FULLY CHANGED .NOW ITS ONLY GREEN COLOUR .TV COMPANY NAME IS THOMSON.HOW IT WILL CLEAR?


Your TV color drivers could be at fault. They run very hot and sometimes develop dry solder. You can confirm this by hitting the side of the TV when its on and see if the color comes back. If they do or even flicker get somebody to resolder the CRT base pcb of the TV.

Red colour appearing on screen


Your tv could have one of several faults. None of which are to be tackled by anyone except a qualified engineer due to the electric shock hazard.the first problem could be the crt (tube) the second could be the componets on crt base circuit board ie resistors or ic.
With a tv 9 years old it may not be economical to carry out a reair.

Colours missing from tv


There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

My TV colour has changed


You have lost red which could be the red driver integrated circuit or associated components or it can be the CRT, you will need to let a technician have a look.

TV COLOR WENT BROWN IN COLOR


It could not be the playstation that would cause the fault. The set was probably going to fail anyways.

A brown casted picture sounds like there is a loss of the blue colour drive in the set.

Some TV sets have colour temperature adjustments in the user menu. Check to see if your TV has that option, and that the colour temperature is properly set up. You can refer to the TV's instruction booklet for details.

A loss of blue drive can be from failed components in the video path, or in the bias circuits that control the CRT's cathold current.

It is also possible that the CRT is going defective, and is losing emission from the blue colour electron-gun.

You will have to bring the set to a service center that has an experienced TV tech who can make proper diagnostics, and give you an estimate for the cost of repair.
