The set is in shut down mode due to a fault detected in power supply/vertical or horizontal deflection circuits.
The common problems with this model that will cause the symptom you describe are bad power supply capacitors, bad flyback, bad HV cap in horizontal output circuit and cold solders especially under flyback area.
These are only the most common problems and it could be any number of other faults.
If you have electronic (TV) repair experience check the items mentioned, otherwise it's best to seek a qualified RCA tech for an estimate/service call.

Check the CRTs . That model was notorious for laser like cuts right around the neck by the yoke. I just had one today doing the same thing. The CRTs are no longer available so the set is scrap. I hope that's not your case. Let me know.
unplug remove the back "CAREFULLY" slide the the plastic board assembly out do not unplug anything check near the flyback for a large grey capacitor check for burn marks underneath it if no check at the front of the same board inside one of the heatsinks for a swollen capacitor if thats not it you need a flyback and or horizontal output
This is a coil, now a NOISY coil.. It is a common problem, and happens often. The whine is caused by current passing thru the copper windings and making them vibrate! A commonly accepted repair for this situation is to squirt some regular old super glue into the copper windings and let it harden for a few minutes..Viola! no more whine!
You need a new flyback thats what the 3 blinks means. you can get a replacement flyback at the following link and they give free tech support so you can easially install it yourself you need flyback 259296 . Heres the link.
The beeping noise is usually related to the Horizontal out put transistor or flyback being faulty or one of the coils are loose near the flyback. If you remove the rear cover without touching anything can you tell if the beeping is coming from the large transformer with the red wire coming out of the top or is it coming from a black transistor on a aluminum heat sink.
Sounds like the flyback is bad you can get a new flyback number 259296 at the following link and they provide free tech support so you can install it yourself. heres the link. http://servicemanuals.vstore.ca/
Try removing the back panel and try to power up the set and see if you can determine if the popping sound is coming from the flyback, in case your not sure what a flyback is it has a large red wire coming out of the top of it. If thats where its coming from let me know as you may need a flyback.
