Too many possibilities to predict if the fuse replacements will make the set function again but I suspect your main power supply has failed so if the fuses blow after replacement, you may have to have the supply repaired or replace it.
You might check, using your model number, at the site below to see if they have a power supply 'pull' available from their stock. They part out retired sets of all kinds.

You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

3 times standby red light blinking shows that lamp cover has not been placed back properly after lamp replacement.
Make sure lamp cover, (the first thing that you removed to replace lamp in tv) is fixed securely then turn tv On.

it is going in safeguard mode there is some problem in circuit

call tech support...tell them # of flashes

the red flash you are talking about im assuming is the screen going red
that usualy means a red picture tube they break down
one way to tell turn the red screen control counter clockwise and see if you can control the tube gain
and then you can lightly tap on crt neck and i do mean carfuly and see if it flashes it most likely will and you would need to change the crt and reset it up

most possible cause is failed convergence ICs. Unplug the three wires for the convergence yokes then try powering up the set if it powers up the Convergence Ics need replacement
