Hello everyone,
I have a 32=94 Sony KV-32HS500 Trinitron flat screen CRT set. I acquired this set from a friend of mine who stated that the set led was blinking 6 times. Having prior knowledge of this (very common) issue I decided to see if I could resolve the issue. I replaced both MCZ3000D chips with the (updated) MCZ3000DB. These chips were purchased from Prelco in NJ (now out of business). After replacing these chips the set has worked flawlessly for the past 5 months.
This brings us to present.
Upon turning the set on last night, I could hear program audio but no picture. The set clicked and appeared like it would turn on however it shut down and I received 5 blinks. I attempted to turn on the set approx 5 or 6 times over the next 24 hours. I experienced the same symptoms. After about the 6th try, I now hear no audio, the set immediately shuts down and the led alternates between 6 and 7 blinks. I was able to find the service manual recently with schematics. Does anyone have any suggestions or a likely place to start looking? Any and all help would be greatly appreciated. Thank you in advance.
