My sony 52 rear projection used to flash red and then turn off. If I pulled out the plug for a minute and plug it back in it would turn on and work fine for days. Now it flashes blue and turns off and trying to reset it with the plug wont work. It does the same thing everytime, it flashes blue and turns off. So, whats wrong and how much will it cost to fix it. ?
These type of automatic tv shut down problems arise mostly due to a damaged power supply unit.So my advice is to first get it checked and then repair it or replace.
Your blue tube is bad .there is no replacement tubes you must send your tube to tucker georiga video repair.
