How many times does it blink? It should blink a series of blinks pause second then blink again if it is in protective shutdown. Try to count the blinks then let me know if ts putting out a code or not.

Sounds like a highvoltage failure. might be the flyback or focus circuit too. oddly I cant find any useful info about 10 blinks.

II get sound for about 15 sec. but no picture and then shuts off

kp57ws50_57_in_rear_projection_hd_228277.jpg Problem with Sony KP-57WS520 57 in. Rear Projection

This model is really prone to one problem in particular--screen even briefly comes up bright red, green or blue and set shuts down.

15 seconds from turn on front power light should blink as set checks several things internally---if something wrong it does not let picture show.

Usually after shut down or failure power light will blink a sequence of blinks but not always depending on problem.

Did you see the screen at all go red, green, or blue before?

the more you tell me the better I can help

No picture or sound - Error code with Six blinks

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206
