whats the problem and just tell the authorised service in cochin

when I turn my tv on it takes 10 to 15 minute to start working and it comes with a lot of colored dots on the screen and these dots do not come away without turning the tv off and back on I do not know if its power supply or bad screen thank you

Half the screen has vertical lines going through it from top to bottom, i reset all the menu settings, and try switching in and out of shop mode but nothing seems to work. I switched between sources and they are still there. Has anyone else had this problem or know if this means the TV is broken or will I be able to fix it.

okay only on of them does this: but when the screen is black or just dark 2ss thick purple horizontal lines crawl slowly upwards can I fix this or is it permanent? clue: a black-light is behind the TV does that have anything to do with it? I’m thinking of taking this TV back.

I have to hit the power button on the tv and simultaneously hit the volume up and down buttons furiously to get the tv to come on. This works about 60% of the time when i want it to. Sometimes the tv will turn off itself, but not usually. It has a great picture, i just don’t know if it’s worth getting it fixed. Anyone have any idea what it may be, could it be something simple like a short or loose wire?
