Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
Hi all,
hopefully someone on this board has an idea on how to begin with troubleshooting this problem.
The monitor AOC AGON AG273QCG (curved 27" QHD monitor) has problems refreshing every 1 to 2 seconds or so. A line appears in the middle of the screen and the lower half of the screen is shifted to the right.
See attached picture.
I am leaning towards an issue with bad soldering of the graphics chip, because the problem used to go away after some time (minutes) but now it is here to stay.
However, this could also be related...08-12-2023, 02:36 AM -
Hi I need help with a Samsung un43nu7100 BN94-13191C/BN41-02635A with boot loop problem even with tcon jumper.
I've already try tape method and same happen, if I disconnect both flex from mainboard to panel tv boots normal even I hear Samsung sound.
When I solder jumper to make t-con work with or without panel or panel cables connected it still reboot or power cycling.
What I noticed is that there's no voltage in VHG, HAVDD, PANEL_3.3V, AVDD_17V or 12v near dc-dc chip.
I check capacitors and diodes and didn't find any short IN MAINBOARD.
Measured all power supply... -
Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)...
