Question about JVC AV-48WP30 48" Rear Projection Television
We had red, green & blue ghosting problems. I replaced both of the IC chips (STK392-110) with aftermarket chips, things looked and worked great, no smoke, or red diodes or resistors. I know that the solders were good & plenty of heat grease on them. I Closed it all back up. Next afternoon the blue started ghosting again. Later that evening my husband turned it on and the screen went black, started making popping noises and the power indicator light was blinking but alternating between high & low light. Any ideas? I am debating on whether it is worth ordering the complete convergence board for almost $300 from JVC or not. I do not want to invest a lot of money into this TV. I Have since bought a 50" plasma, but would like to use the JVC for gaming. Any help would be appreciated.
The biggest problem you stated yourself. You bought aftermarket type IC's. You should have been smarter and purchased the correct IC's for the set. All IC's are not alike, even with the same number on them. Aftermarket IC's are just that. Built in China or are factory rejects. You might get away with replacing the iC's again from a reliable dealer or you might have messed up the power supply in the meantime. Good Luck
