Re: Sony KDL-40W600B 6 blinking lights
Well, this was indeed the case: one of the B strips had 2 burned LEDs (out of the 5). I replaced the LED strip today, and so far so good.
I thank you all for taking the time to answer. You really helped me narrow down the problem and eventually fix it.
Best...

Re: Sony KDL-40W600B 6 blinking lights
yohnsee:
whenever I was able to get to the service menu, the only errors show up under 006 BACKLIGHT, with a counter equal to the number of times the error came up (47 the last time I checked). There are also numbers indicating the exact time and date of the last 3 backlight errors.
There is no TCON board I can readily access in this TV.

Re: Sony KDL-40W600B 6 blinking lights
Possibly. Some more data: sometimes, just a split second before it turns off, the picture becomes suddenly dimmer, and then it turns off. Also, I had it set to "vivid" mode, which had the brightness set at max: it couldn't sustain it, and it would shutdown with the 6 blinks. Then, I set the picture to "standard", and it was able to stay on longer (initially for hours, then for only minutes).
Does this strengthen the bad capacitor argument? Will it be on the BAXL? Because the LD board, which...Leave a comment:

I tried the factory reset: no change to the problem.
I had the latest firmware. I hesitate to reapply it, in case the TV turns off before the firmware is applied. I am not sure whether it can enter protection mode while the firmware is updated.

Re: Sony KDL-40W600B 6 blinking lights
Thanks R_J. If the LEDs are the problem, is there a service manual on how to disassemble the panel to get to the strips? The service manual Janos posted mentions (page 20) the "LCD Panels Service Manual", but I haven't been able to find it for this particular TV model. Any pointers on how to disassemble?

Re: Sony KDL-40W600B 6 blinking lights
Hi Janos, thanks for replying.
a. indeed the manual you posted says that the LCD panel is the most likely culprit when we have 6 blinks. But the manual I posted, on page 19, considers only the BAXL and the LD as possible sources of the problem.
b. It still turns off even when I get in service mode.
Thank you much

Sony KDL-40W600B 6 blinking lights
Hello all, I need some help figuring out whether the TV can be fixed.
The symptoms:
a. TV powers up, tunes to a channel, there is picture and sound, and after a few seconds it powers down, with the standby light blinking 6 times.
b. Sometimes, it will power down after a few minutes, and yet other times, it'll stay on for hours.
c. The service manual (see attached) says to check JL9106 (Backlight_mon) on the board. It reads 1.6V in standby, it fluctuates for a second or two on powering up, then it stabilizes to 1.6V, and then drops to... -
