TV is randomly showing colours rather than the channel its supposed to be on, How do i fix?

I bought the Celcus 48" 4K Smart tv about 2 months ago, and everything was working fine until all of a sudden the TV started showing colours (the whole screen will switch between red/green/blue/white/black every 3 seconds or so) the tv will still however play sound in the background. Help?

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

    Thank you for getting back to me so quickly, in the end i took the to back to the store to simply get a replacement, which is working fine, but if i encounter the problem again I'll do what you have suggested. I asked in the shop if they have had anyone else complaining of this and they said no so I'm hoping it was just a faulty tv and not a problem with the batch number etc. But thank you anyway.

Philips 26pfl3512 LCD TV loud power supply discharge


The "certified servicers" should have been able to identify a power supply that is breaking down at random. At random failures only occur when the TV is in your home, never in the shop. :-}. Eventually the power supply will fail completely and will have to be replaced.
