Sony 46" LCD Model# KDL-46W3000 Around 3 years old.
After firstpower up of the day the tv will stay on roughly 3 minutes and then shutdown by itself and the standby light will flash red 6 times. I can turnthe tv on again, but it will power down again with the same flashingcode. If I repeat turning it on about 3-5 times it will finally stay onand not power down again. I noticed that if I turn the tv off at nightand then turn it on again in the morning the problem will not occur. IfI wait and turn the tv on again the next day in the afternoon theproblem will occur again. It seems like as long as it is not poweredoff for more than 8-10 hours the problem will not occur. I am thinkingthis may be a common problem, and something as simple as a leaky cap,but I was hoping someone has repaired this issue before and can give mean idea where to start. I can do component level troubleshooting, but Ifigured I would ask and maybe someone could give me an idea on whichcomponent to start with. Thanks in advance for any help.

Welcome to Agoraquest! I found the following items applicable to 6 blinks for the KDL-46W3000:
Intermittent shutdown 6X
Symptoms / Customer Description
Intermittent shutdown.
Solution
1. Found loose CN6706 on DF2 caused intermittent shutdown.
2. Found CN6154/pin 10 and 11 was not push in all the way.
3. Check all scews from the DF Board, it can cause the intermittant 6X.
Subject
Dead 6X

set will turn .and then shut down with 6X
Solution
No FB from the balancer boards, replaced balancers and fixed set.
P/N for Balancer based on Model and serial number.

Break/Fix information may be based on a single instance of this problem.
It in no way indicates a serious problem and
is only provided as an aid, in the case that
you are repairing this model for a similar symptom.

Thanks for the info. This is exactly what I was looking for. Maybe not the fix, but a good place for me to start. I'll post again when I figure the problem out.

So far after checking the suggestions listed above the tv has been working. I don't won't to get my hopes up because it seems like the problem came in spurts. I can say that cn6706 seemed loose to me and I pushed all the pins down. The other things listed above seemed ok, but I pushed pins on everything I could find.
afroz,
I do not remember the board #, but i did see an orange flashing led. I do remember that when the tv was on and working correctly the led was flashing. I remember it was a small led mounted on a board in the middle of the tv under a metal cover in which you had to take off or look through the small holes to see it, but like I said everything was working ok while it was flashing.
