Its the problem of the tv internal board as some components on the tv main cirfcuit board gets over heated and the tv reaches to HANG MODE and nothing happens.so just replace the IC 456UI on the main board of the tv which is inside the tv.which controls the tv internally to function it.if that ic turns faulty this can happen.if you are not familiar with reparing then get it replaced from a proper repair center.
thanks.

IR sensor is the infrared sensor that detects the signals from the remote. When it is bad you need to either replace the sensor ot the whole IR circuit board. Try using a diffrent remote to check if your remote is not faulty.

That is a faulty ir sensor on tv panel, try removing battery from remote, if problem stops, then it is the remote. if not , then the tv must be repaired and the ir board on tv replaced.

My samsung smart tv hdmi ports do not work anymore


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.

One for all universal remote i am trying to program my seiki television. I lost the original remote and the power button on the television is broken so I cant turn the television on


Always better to buy a genuine replacement. The problem is that if I remember correctly, Seiki don't actually make the television, which is why it never features in the Remote Code Lists. I have just checked three sites.

Truetech 10 inch under the counter tv is stuck on channel 2. I need 3. Channel buttons on tv & remote do not change 2 to channel 3. Unplugging, Resetting hasn't worked Any ideas?


Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.

Veon tv manual


The eject button on the remote appears as an upward-pointing arrow with an underline - see below image. The eject button on the TV has a similar symbol.

However, I suspect that in your case, you might not be having a Remote.

This link says that your TV doesn't come with a Remote and DVD cannot be ejected without the remote :
