Did you check the DC voltage on both end of the SMD fuse on the T-CON board against the chassis ground?Never stop learning

Bad tab bond fault. Common fault, not too bad to fix:

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... -
Hi, hoping for some views on this one which I've not come across before. The TV generates an image that has 12 noticeable bands across it. The image is still there and accurate, but the colour (or perhaps the brightness) changes gradually across each band which creates a noticeable 'step change' at the edge of each band. Given it's a 4K TV with 2160 rows of pixels, I'm guessing the 12 bands correspond to 12 gate drivers of 180 rows each. If this guess is right, then perhaps:
a) all the gate drivers are malfunctioning the same way (which seems unlikely), or
b) the Tcon board is malfunctioning,... -
Hello gurus, hope you can assist me...
I have a Sony KDL.40P3600, with an issue on the left side of the screen (pictures attached).
I think the problem is the panel, but before send it to trash, i would like to get a second opinion.
Thanks in advance. -
