Re: KDL-60W600B won't open just Red Blinks 6 times

@vinceroger69 thanks for headup, appreciated your help bro, @Tom can you advise how i can check on PSU CN6801 & CN6802, i mean multi meter should be on 20 DC rang right? & out come volts should be 3-5V right? does tv should turn on while checking CN6801 & CN6802? can you point out me where i place multi meter probes,
looking forward to your reply,
Thanks.

Check the voltages going to the backlight of the panel, I suspect along the connectors CN6801 and CN6802 on thep ower board.

6 red flashes- backlight issue, bad main board, or power board or inverter boards- check standby volts on power board. "backlight on" volts should be 3-5v from main logic board then 24v to inverter

Thanks Tom, as per service manual, it says 6 red blinking means either its (Primary) Most likely defective part. (POWER SUPPLY or LCD PANEL) and (Secondary) Possible defective part (MAIN BOARD or TCON or LVDS FFC) attached file is service manual with screen image of above predictions,
appreciated your help,
Thanks.

Re: KDL-60W600B won't open just Red Blinks 6 times

Sounds like the TV is detecting a fault with the T-con or other part and shutting down but given you have 12V at the t-con there is no short or fault with that part of the power supply.
I would look for a service manual to check what a 6 blink code means.

Hello again Tom, i use to test with power turn on tv and fuse f102 have 12.38 V out put for one to two seconds while turn on tv after 2 seconds it goes to 0.00 V, i set my multi meter on 20 DC range, since i start tv, it start with white light and in one second it turn to red with keep blinking 6 times, any suggestions will be appreciated,
Thanks.

Hello Tom and thank you very much for help and support, much respect, do i need to check again on above fuse f102 each side 12V while tv turn on,
Thanks.

Yes, turn TV on, watch the reading, does it go to 12V.

Use the "20V" DC range of your meter, or the closest similar one, must be higher than 12V.

If your multimeter is an auto-ranging one (given what you've said above I don't think it is, but good to be sure), make sure you lock the range as it won't range-up quick enough to capture a quick pulse. So you'd lock it at 20V or 40V or whatever its closest range is.

Re: KDL-60W600B won't open just Red Blinks 6 times

Fuse is OK, given those results.
Try checking each side for 12V supply, when the board is installed in the TV and the TV is turned on.
(It might go to 12V then turn off after the error code occurs.)

F102 in yellow box
Use your meter set to ohms and place probes on each side and measure resistance which should be 0 ohms or a few ohms at the most due to the resistance of your meter leads. Test with power off.

Thanks for help dick_barton, as per your instruction i test it fuse F102 on said location with multi meter set on ohms & result is below,
with rang of 200 = 0.06
with rang of 2000 = 001
with rang of 20k, 200k & 2000k = 0.00

waiting for your reply & support,
Thanks.

Hi,
Thank for reply, can you please help me to tell i need to check fuse F102 with multi meter right? and i not understand this (5A on the Tcon is not open circuit?) also i upload T-Con pics where i mark with red fuse F102, please confirm whether this is the one which you advising, appreciated your help,
Thanks.

Re: KDL-60W600B won't open just Red Blinks 6 times

Look for these components on the PSU PS6800 (fuse to ground) and Q6814. The fuse may be open and the transistor shorting.

Thank for reply Andrew, sorry but i can't find PS 6800 & Q6814 on PSU, can you point out to me where is it located in below PSU pics, also please help me how i check with multi meter, i.e set multi meter on which range, and do i need to plug in power & turn on tv than check? since after tv turn on it keep blinking red flash 6 times,
Appreciated your help,
Thanks.

Edit: added Tv back picture also,
Thanks

Have you checked the fuse F102 marked 32V, 5A on the Tcon is not open circuit?
