good evening! This tv had a panel synchronization problem that I improved by canceling some outputs from the left lvds of the tcon. but a faint horizontal line still persists, and it doesn't quite look perfect. Is there any trick to know the lines to cancel? I have been reducing the number of canceled lines, but it does not improve. Let's see if anyone helps. thanks in advance.

Hello again everyone,
This is my latest mission, to try getting this Sony tv back to normal working order…
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... -
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... -
