Re: sony wega clicks
There are two flat ICs on the main deflection board. they have around a dozen pins or so. the part number is MCZ3001D if you are having problems only at turn on then those are most likely the faulty devices you could take time to figure out which one is bad but just replace both if you had the ambition.

Great set, weighs a ton and expensive to fix--all parts are Sony only--in my view replace it with a LCD etc which will be cheaper---most of these that come to our shop that are fixed average over 200 parts and labor.
The primary power supply is good,maybe the horizontal output transistor is deffective thats why there is no high voltage supply in the picture tube because theflyback have no supply voltage and oscilation.So check the harizontal output transistor and replace if deffective.
My 36 wega did the same thing last week it must be contagious. Blinks 7 times mostly but sometimes 6 if hit power switch again. The problem is the D-boards shorted Flyback high voltage transformer but the ones Sony is selling $130 do not hold up and seem to burn out in a few days, yes twice bitten. Finally they send me new D-board can't wait to see if this fixes it once and for all. The board costs around $200 but is worth it to get it running again.
MOST LIKELY THE ERROR 3 IS THE 200V LINE TO THE CRT DRIVE IC.IC702. ON THE CRT PC BOARD. IT ALSO COULD HAVE GONE OUT IF YOU HAVE HEAVY USAGE ON THE SET 8-12 HRS A DAY. THE CTR COULD SHOT AND TAKE OUT THE I.C. AS FOR IS IT WORTH FIXING, THEY DON'T MAKE CRT TV'S ANY MORE AND THE NEW SETS SEEM TO HAVE A LOT OF PROBLEMS. DON..
