Did you even want to test the main board or just throw boards at it until it is fixed?

Good afternoon to all of you. First of all sorrybfor my bad English. I have a sharp aquos tv ,and i m dealing this problem. If i leave the power cord disconnected,then it starts normally for one minute approximately. After that the tv restarts and only the touch panel lights working for about 10 seconds and only 1-2 seconds lights up the led panel. After that loop again. No signal lights in center. I think probably is a power supply problem . I can see 5 v ,13.3v in 4 pins . I m a mobile technician and i can follow your instructions if you yave some suggestions. Thank you in advance. -
I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp... -
Hello!
I'm a few days old into this TV screens repair universe so please bear with me.
Recently, and all of a sudden my 40ā 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but Iām shore this is not an OLED.
- I did the classic unplug and hold power button to discharge the caps but it didn't help.
- I did a factory reset as well... -
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 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)...
