Question about GE 31GT740 31" TV
Model:27gt722 chassis: cte-203ad5 sound ok, no video. it does not illuminate filament CRT
I found one of these that had an inductor coil which is in series with the hoizontal output transistor base open up. It had a bad solder connection where it goes through the circuit board. This might be what happened to your tv. If so, it needs to be resoldered. What happens is that you loose horizontal drive and since the voltage that lights the filiament of the picture tube is derived from the flyback transformer this voltage is gone. Another possibility is that you may have an opem filiament (rare) or a loose connection on the picture tube driver board which is mounted on the neck of the tube. Stargazer
