The set is attempting to start and is experiencing an overload, probably in the high voltage circuit.

CRTs are common to go bad either internally shorting or coolant leakage which flows down onto the crt boards and shorts them out.

Sorry, no magic button answer for your problem.   

Cut and paste from another thread I answered:   

I've worked on these units.  They are prone to CRT coolant leakage.  This usually shorts the driver board and/or mainboard.  It should be obvious if it leaked coolant.  If you lucked out and only shorted the driver board those can be had for $50 new.  Replacing the coolant is a simple fix as well.  A cracked CRT seems odd.  Those things are pretty tough.  It usually leaks at the rubber seal, as if it wasn't tightened down enough during manufacturing.

The leaking coolant and resulting shorts causes the unit's electronic protective functions to kick-in and shuts down the unit.

What have you done so far?  Is there obvious signs of coolant leakage?

I have the same problem. Mines a rear projection tv. Does that even have a CRT? I'm certainly no expert especially on this type of set.

thanks

you would need to check the LOPTX for no voltage , low voltage , or a voltage drop , also rca is known for needing new solder jobs ( one of there kits to fix is solder and solder paste)
that would be the first thing to check, LOPTX ( low output transformer ) then the solder jobs ( test for continuity thru hot components solder connections to the next connection) then check capacitors in power sec. ( DMM on highest resistance setting.) also look for protection fuses that are open , last but not least the horizontal output trans.( on a big heat sink)
whats your results?
