1. Changing from DTH (TATA Sky) to ch-1 ... to ch-37 2. Power is not switching off from the 'Power' button on the front pannel. 3. Power is switching off from the TV/Video Switch on the front pannel of the TV.
First you have not indicated the brand or model but that aside the issue appears to be a bad micro switch or the keyboard with the controls on this set, I would suspect the source or TV video button first, not the plastic button itself but the tiny switch it activates, that is bad---have someone get at that and disable or remove that and the set should again function in a normal way.
The micro switches are momentary and should only operate when pressed, the problem is they fail, and with no one pressing the switch activates on its own.
SOURCE: remote ok but no respondindg on tv, pannel buttons not function.
then best idea is buy new tv
SOURCE: When trying to switch from AV1 to AV2 with the
The Red, White & Yellow connectors are your composite inputs usually classed as AV3 or component. The AV1 input is a Scart connection, if you have a scart cable, connect this as your AV source & the TV will switch from AV to component.

You don't list a model # If this is an lcd tv, you have an issue with the backlight inverter module, I would first check the power supply for potential of swollen capacitors, the tops will swell up and sometimes leak out electrolytic oil. Either or it's repairable with a little knowledge and some luck!
