Default KDL-55hx800 has 6 blink code

This set will run for about 5 minutes then shut off and the standby light blinks 6 times then repeats. I can press the power button and it comes back on but for a shorter time. I have the service manual and in the flow chart I am supposed to check the voltage at JL2565 to determine if the bal board or tcon failed. Does anyone know where JL2565 is located since I have looked and can not find it.

How about uploading the service manual you have? or the link to it?

Per service manual I found, 6-blink = Backlights Error, page 9.

I see it is a backlight error but according to the service manual I need to check the voltage at JL2565 and I just can not find that. I am pretty sure all of the led's are good since it does work for 5 minutes but without checking for 2.65V at JL2565 I can not isolate which board it might be. Anyway I have attached the service manual and page 29 is where it looks for the 2.65V.

Default Re: KDL-55hx800 has 6 blink code

I am back trying to fix this tv and need some suggestions/help. I have checked the voltages on cn6753, 12v reads 0v GL-Error is 24v and all vled-vcc are 24v led-on is 3.3v. cn6152 standby is 3.3v, ac det off is 3.3v, power on is 3.25v, audio 12v is 12v, t-con vcc 12v is 12v, and t-con on is 3.25v. on the led driver board all 4 vcc led test points are 34v. If I unplug cn4002 from led driver the tv will stay on and never shut off. When I disconnect the lvds cable from the balance board I get a nice white background with no dead led's in the picture, it gets a little darker and I can see a bright led bottom center. It is really pronounced when the screen turns red then shuts off. I did send the balance board in for testing and it was fine. The service manual says change the G board next which I believe is the power supply but I don't think that is it and now I am wondering if maybe the led driver or t-con might be failing. I did freeze spray the led driver board and it made no difference. Bottom line is does anyone have and suggestions? And now as I am writing this the 12v on cn 6753 reads 0v and that is most likely the problem.

Hi I googled jl2565 and found this CN2561 at PIN 3. It is for different model but may help.

Thanks, I had also found that ant the voltage is at 3.3v so that leads to g board or tcon. at this point I am going to either order a power supply or the repair kit. Since I do not have the 12v I should be getting the 2 blink code with that missing. I am beginning to not trust the sony blink codes.

Hi @nwcs, did you find the fix for your issue? Was it the power Supplu? I have the same issue but with 4 blink red lights. My tv is 46HX800 very similar to yours.
Thanks

The Sony KDL Service Manual is totally useless. I just ordered the repair kit from shop jimmy. Hope it fixes my KDL-55HX800. 2 blink code.

So I replaced all the components in the repair kit and now the TV is worse. I cant even get the relay to switch.
