THIS FIX JUST WORKED FOR ME!!!! THANK YOU TREMENDOUSLY JP!!!! I have a Sony Trinitron model KV-32FS13 which is a 32 inch flat screen in the front, manufactured June 2002 and weighs a ton. I had the exact same problem after 7 1/2 years of working fine. The display would go to a black screen after being on for 1-5 minutes with the audio still in tact. The red light on the front of the tv would blink 5 times then stay on. I could unplug the tv and plug it back in and same thing would happen, come on for 1-5 minutes then black screen. All it took was a turn of the plastic screw and wha la!!!! Thank you again, just saved me a couple hundred bucks on repair. This really buys me more time to research and figure out which LCD flat screen we want when the time comes to upgrade to HD, etc. Again thank you!!!! Matt
