Do measure the voltage on the 10 pin connector ?Comment

Re: Sony 42w653a
So it uses an external power supply to power the internal combined mainboard/power supply.
There appear to be a number of fuses marked on the board. Have you located and checked each one.
Have you checked the incoming voltage from the external power supply is 19.5V when connected to the tv.Last edited by dick_barton; 08-25-2017, 01:17 PM.Willing to help but I'm no expert.Comment

Re: Sony 42w653a
It uses a power supply similar to a laptop,I have not checked as wanted some advice how do do this,I'm armed with a multimeter,I know you ground the black and test with the red,set to dc volts ? So little bit of help I am a quick learner...Comment

Re: Sony 42w653a
That's correct.I'm armed with a multimeter,I know you ground the black and test with the red,set to dc volts
To test the fuses, set switched off and meter set to ohms, place your red and black probe on each side of the fuse and it should measure 0 ohms or close enough for a good fuse.Willing to help but I'm no expert.Comment

Re: Sony 42w653a
Thank you for the advice,when testing the input voltage,can the set be on (currently only flashing when on) be best to start to see if right voltage is coming throughComment

Re: Sony 42w653a
Voltage, yes the set needs to be plugged in, else you'd measure zero.
Ohms, no. Some cheap meters can be damaged by measuring ohms when voltage is applied. Most are okay, just not the very cheapest. In any instance, it will not give you an accurate reading.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

another thing is even after i unplugged the power, The tv keeps red blinking 3 times for 2 almost 2 munites -
Good Day.
I just replaced tcon on my sony kdl 65xg9505 and getting green amber leds blinking. all voltages are ok according to working sequence.
i downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?
green amber blinking stops after while and then starts again. tv responds to remote control on off etc. before installing new tcon backlite was coming on without backlite... -
Have KDL-55HX850 that seems to have been hit by power surge.
Blinking red 3x - clicks on/off on the power supply board when power is held in.
Replaced Power Supply G board - same response.
Replaced main BAP - no response at all. Seems worse, maybe bad board.
Replaced main BAP with a 2nd board - back to blinking 3x similar to original.
Checked speaker impedances ok 8ohms each.
Where are JL6002, JL6005 test points?
Ideas for what next to troubleshoot?
Could it be T-Conn or LED board? Seems that the troubleshooting... -
This is a CRT I sold a few months ago and it's came back with this weird issue. It's intermittent, but not a thermal fault, or tap sensitive - just completely random. The right side of the picture completely blanks out (picture is not shifted). The on screen display is unaffected though, so not a fault in the line section. Anyone seen anything like before in a CRT? -
Sony KD-49XF9005 it power up to android boot screen and turns off immediately with continuously 4 red blinks ...
