The high voltage does come up but the set goes into shutdown because is sensing a problem somewhere in the set,the shutdown circuit gets activated when the high voltage is too high, a problem in the horizontal deflection circuit or because there is a problem in the secondary of the output transformer,this transformer helps develop voltages supplies and if one is missing the set senses the problem and shutsdown,there is another possibility and is related to the picture tube,there is a resistor in the crt board ,it should measure 51 ohms only ,sometimes it opens up and gives you same symptom.If you are familiar with tv service you can check this resistor and be alert of the other possibilities,if you are not too familiar be safe and get assistance from a servicer.

Tv have "LAMP" indication LED light blinking?The tv projection lamp is dead,require changing.Hearing alot of clickings sound too?Mean the board,call the Ballast board is dead.Require change the Ballast too.The Ballast board,the board that help to ignite the projection lamp.
When u turn the tv on,u hear alot of clicking?That mean the Ballast that help the projection bulb to work is dead.Change the Ballast,might as well change the bulb too.U don't know what is the condition of the projection bulb in.
most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each
3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures. http://servicemanuals.vstore.ca/
