Hello and welcome to JustAnswer! I am Pete, a TV expert, and I'm happy to assist with your question today.
The 4 blink error code on your Sony SXRD 60" TV indicates a fan error.
You may also have to replace the smaller fan, as these fans tend to fail over time and need replacing.
To work out the correct direction for the fan, observe the air flow directional arrows on it.
If you have a voltmeter, can you also take readings of the voltage supplied to the fans to ensure they are getting the correct voltage as stated on them?
The fans require 12 volts to run. If you get a lower reading than this, then there is a power supply fault.
The Large fan was not spinning but the Small one was. That is when I purchased the replacement fan. After installing, When I power the TV on, both spin for a few seconds, and then both shut themselves down. Don't have access to voltmeter. The back of the TV is not back on, would this effect anything. Do I have to unplug TV and let it reset or anything like that or should the picture come on when new fan is operational?
Yes, if the back of the TV is not on, this will prevent the TV from powering on.
There is no need to let it reset after installing a new fan - the picture should come on once the back has been fitted.
Let me screw the back on and I will advise. Thanks Pete. Do I also need to unplug TV?
Just read reply, let me go put it back on now.
Put back on, and I now have picture. Thanks Pete.
Glad I could be of assistance.
