POPPING NOISE FROM SONY TRINITRON KV-30HS420

I HAVE A SONY WAGA TRINITRON KV-30HS420. WHEN I TRUN THE TV ON AFTER BEENING OFF FOR SOME TIME IT WILL HAVE A POPPING NOISE FOR ABOUT 15-30 SECONDS. AFTER THE POPPING STOPS IT WILL NOT DO IT UNTIL YOU TURN IT OFF. IF YOU TRUN IT OFF AND TRUN IT RIGHT BACK ON IT WILL NOT HAVE A POPPING. ANY HELP?

Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672

Hi there, we have a sony KV-30HS420 30 inch fd Trinitron that is blinking 7 times and then shuts itself off. We can turn it on again but this problem is understandably quite anoying. What do you think...

There is a power supply fault causing the EHT to rise above 33KV.

High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Hope that points the engineer in the right direction.

Green screen and distorted picture sound is good but no picture

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Sony trinitron KV-30HS420 HDMI

Yes. As long as your PC has an HDMI port as well (or at least a DVI port and a DVI-to-HMDI converter dongle).

Picture and sound problem at 21" sony waga color tv

This is due to problem in deflection area and power supply section malfunction. Make one general service by technical person immediately to avoid major transformer failure problem. Since this is initial stage, the cost of repair is probably less.
