If you can just post the pictures here, it will allow for folks to better help you. Many don't want to deal with wandering around the www just to see pictures.Last edited by nomoresonys; 05-06-2025, 04:55 AM.Comment

Hello again everyone,
This is my latest mission, to try getting this Sony tv back to normal working orderβ¦
I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried... -
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... -
HI guys
I got here a Sony 65X950G - I tried to find any repairs guides for this model but not many online
here is the issue
I have Sony and android logo. but then 4 led red flash lights front of the tv
I have 3.3v ref. 12v reg then T con 12v when I press the power on button
but then I get black screen and 4 red flash light at the front LED
but I get 3 led flash on the LED driver board.
I check that few X900F or C YouTube repairs, seems that if you have 4 led red flash it could be due of LED black light error
so I tried... -
I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.
I have tried a Cold Reset as per the service manual.
I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.
I have looked all the way through the service manual and tried many online... -
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...
