Question about Sony KP-53S70 53" Rear Projection Television
I got a tip on here about blowing out or cleaning the cooling fan, but can't seem to find it. Am I missing it, or does this model not have one? P.S. it has no picture, and LED blinks 4 times then stops and blinks 4 times.
Unfortunately, you apparently got information from someone who has not had training on your set. A 4 flash on your set indicates a vertical stop, meaning that the vertical drive circuit has shutdown. Possible causes are a bad vertical drive or vertical output IC. I can't be more specific because I would have to check a couple of things, starting with the 135 volt power supply line to see if it is coming up. You can stop looking for a cooling fan because this set does not have one.
