When turning on TV just blank screen no sound or picture. The circuit board was by itself on the top of the TV
TV Technician: Shahid, Technician replied 3 years ago
OK, it seems you are talking about t-con board of TV where you replaced the chip.
Where did you get the replacement chip from?

We bought it online
TV Technician: Shahid, Technician replied 3 years ago
OK, is it possible for you to take a good picture of back of TV to show all the circuit boards there and attach it here or upload at any file sharing site and post the file link here so I can view it?
Also, a picture of board and replaced chip would be very helpful to troubleshoot the problem bit quickly?
Thanks.
