Sony Rear Projection KP51WS500 Problems Help!

[mknight52]

Unit is 3 years old, suddenly wont stay on longer than 3 sec o
so....standby switch blinks 8 times, Sony's online site codes say chec
IC406....I ordered online service manual, but it makes no reference t
an IC406 I searched the entire pdf doc...mmmm, so I did a littl
digging in the SM, it says 8 blinks means a transformer on the D boar
is bad..... ...I'm thinking of ordering the d board for 139.00 and jus
plugging in. But I am confused by Sony's code blin
descrepancy....anyone have any ideas?

Thanks,
Mike

Not the whole D board, just the HV block?

Just the BLOCK...follow the HV lead from Fly to the BLOCK
it sits up a little ..

Could be either the FBT or the HV block. Seen both. Test the transformer
and if it checks ok on both ringing and drive tests change the HV block.
Could still be a flyback, as I have had them test ok but not run, but
rarely.

There is no discrepancy. The blink codes just get you in the ballpark and
provide a starting point for troubleshooting. They are not a symptom-fix
database.
