Chosen Solution
Tote Vision 12 inch LED TV makes a mild tuk,tuk sound when kept on for a few hours and then NO pic .Again if the TV has to function again I have to switch the 12 volt external adopter power and connect again.Then it works fine . I will appreciate if any one give me a permanent solution to raj.ryerson at gmail dot com
@rajryerson sounds like you have either a bad power supply or a bad power board. If you can give us the complete model number of your TV so we can try and find the proper schematic. If you already remove the back cover from your TV post some pictures with your question. Use this guide for that so we can see what you see. Update (10/14/2017) Let’s see your mainboard. Post a couple of pictures of the board and the power adapter label. You may need a bigger AC adapter something with either a higher voltage or higher amperage. Check the capacitors on the power board since they could as well be at fault. Your TV require a 13.2 V power supply.
