Question about Televison & Video
I have optonica TV model CS5145A brought from mumbai in 1993. But since a couple of months TV automatically trips when I increase the contrast and decrease the brightness and the picture on the screen is not clear ..So can u suggest me which component has to be replaced?. Already i replaced the SMPS and power resister in power supply circuit.

Replace the capacitor (10MFD/450V) at the powersupply output. Replace with a Keltron or good quality capacitor.If you are talking about a defocussed picture then replace the picturetube base (narrow or broad based on the picture tube) which would cost you less than Rs. 30. Your optonica model normally would come with a narrow base.
