I've got a two year old Sony that doesn't get much use but recently died.
Model KV36FS320 Chassis SCC-S61R-A fails to come on when the power button
is pressed, no relay click, just nine flashes of the Timer/Standby LED. I
checked the obvious: HOT and switcher transistors, and the standby +7.5V...
all OK. I jumpered the power relay, then when the power button is pressed,
the HV comes up (30KV) but drops out after about 2 seconds. Nothing is
getting hot and there is no evidence of anything overheated. All supplies
check OK when the set does come on for that short time. There is a V sweep
signal on the yoke and the flyback secondary supplies appear OK. The set
doesn't stay on long enough for the CRT filaments to light up. Apparently
something is preventing the set from even trying to start up, but what.?
I've run out of things to check. Can anyone help? Thanks in advance!

that is not the chassis ref. you have there, i think you have an ae5.
possibly an open fuse on the HT line (one fo those small black 2 legged
rectangles) AFAICR .

sony codes here. I think you may need to do some resoldering

There is something to remember that those Sony codes are NOT for all models.

Leonard,
Thanks for the feedback. I looked at the Z det circuit and there is a nice
clean pulse going into the M board. Any problems on that plug-in card have to
be a -real- grunt... can't get to half of it while it's running. Perhaps Sony
is right: Board replacement. barf

Well they are good for all Sony Licensed sets Now you may have a Sony
licensed by RCA or other companies nowadays. Wit the Sony name on it
doesn't mean it's a Sony license.
Non Sony license sets don't use the Sony CPU where in lies all the
codes. Like they won't even flash at all..

Rub comes trying to read the meaning in the codes loss of horizontal
could give you a no vertical 4 flash code. Stupid stinking CPUs.

So the point is don't go by the codes.

But Sony's are bad for having power supplies let out the smoke And
smoke is what makes them work.Sometimes they let out alot of smoke. My
trouble shooting method was to rebuild the power supply first thing.
Slowly bring the AC voltage up so not to let the smoke out if there
is/was something else wrong, like HOT circuit messed up. Sony's are and
still will be the main stays of TV repair. God bless those Sony's May
many people buy many more.

glad someone likes 'em!
things i hate about sony are the expensive parts, that akb circuit
which means that even though the set may be good for a few years more
albeit with a tinted pic, on sonys the pic goes totally and you have to
generally say not worth repair. and the fact the design means the sets
are so fussy , you have to use the original parts not subs.$$$$

The blink codes are not the same for all Sony sets. Refer to the training
manual for each chassis series for the correct diagnostics and the caveats
for each. They are simply a starting point and are useful for proceding
with troubleshooting, but not a substitute for it.

You might want to check your facts and specify what products you are talking
about. What Sony liscenced by RCA have you actually worked on? Since it is
nonsense, I am sure that there is not one.

ypu change out your video amp ic on the crt board also the 2.2 ohm
resistor in the 200 volt line

David,
How could something like that make it fail to even -try- to start up? I
don't mean to argue with someone trying to help, but only the standby supplies
are running... it never gets further than that.
