No red light or power


I've had about 3 or 4 similar sets like this....all have had a flash-over around the bridge rectifier to metal chassis. (you will clearly see the flash-over on the metal chassis). Clean back the print re-solder bridge rectifier,fit a new fuse (usually around 4 to 6.3 Amp)

I have waveing in my tv


Hello
Picture waving can be due to many reasons. The first reason is ariel connection. Check it first for tight and not loose contacted. Second one is due to the main filter capacitor connected across the main rectified power supply DC. If the capacitor goes value reduced or opened, waves may occur. If this is the reason, picture will show blooming effect also. Check the mair rectifier bridge also. gopakumar1@hotmail.com

WHEN PUT ON THE TV,THE INTERNAL FUSE BURNED


check input circuit. trace bridge rectifier circuit.. make sure its good.. check tranformer or line filter.

Fuse is probably burning as a precaution because there is a problem in the input section.. either ac side or after bridge

Converting ac to dc voltage


You need to transform the voltage to a level that you require, then 'rectify' your voltage to DC, with a bridge rectifier. There are many different types of rectifiers for different uses. Look on the web for electronics, bridge rectifiers.
