Re: Cap exploded in VCR power supply board


Yes, the diode is connected to the transformer on the left and exploded cap on the right. Have checked the diode. It is fine. Any other possibilities?...

Re: Cap exploded in VCR power supply board


I am not a technician but beginning to learn. I have a multimeter just only know how to use it as a continuity, AC and DC check. May be can learn from you how to check the resister but which resister should I check and how?...

Wonder if this is the appropriate platform. I disconnected my VCR to be found that it could not be switched on again. Managed to replace 2 swollen caps 450v 2.2uF and 25v 1000uF. As I switched on the VCR, the power came through but lasted only for about 5 seconds followed by an explosion of a cap 50v 47uF. I was certain of the correct polarities. Moreover, the exploded cap was the original cap on the board. I replaced the exploded cap 50v 47uF but the same thing happened as I switched on the machine. I replaced the cap for the 2nd time. Again it exploded. Which is the culprit? Pls advise.
