Possible that there are issues on your cable or RF input. check and see if the COLOUR SETTINGS are chosen for the right colour system if not you can manually set the system or reset with auto tuning and auto colour detection. Since there is colour with the satelite channel-- hope it is given to the AV inputs- then the RF signal/IF processs side also needs to be checked for loss of chroma signals or processing.
In the CRT sets, not only Sony, there are many types of failures that can cause a loss of a colour channel.
damaged or warn parts on the CRT circuit board that are associated to the related colour channel(s).
The CRT itself may be failing.
Defective interface socket on the CRT circuit board, or a cold solder connection under the connector or on the the CRT board, or along the path of the related video colour channel.
Intermittant loss or complete loss of the bias voltage supply for the CRT that drives the colour channel in question due to any failing parts, or some cold solder connections.
The CRT itself is going defective and thus failinig.
Cold solder connection(s) on the circuit board.
To find this type of fault it would take an experienced technician using the appropiate test instruments to make the necessary tests.
Considering the cost for the time and the necessary parts (if obtainable for an old set), you may find the set too exensive to have serviced.
Possible the DVD player is outputting in progressive scan mode. Try checking your manual to find out how to turn it back to interlace... with LG, it's either a button at the front, or a menu item in the Picture category... you could also try ejecting the disc, closing the tray and when it says "No Disc" then hold the stop button down for 5-10 seconds... see if that helps.
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.
Go to the Sony website and check out the correct antenna cable and scart lead configuration for your set up. I did and with a few simple connection changes it was like getting a new TV.
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!
