How to exit Burn/Aging Mode into VU 40D56575

[VivekPal]

By mistake, I have on Burn mode into my VU Tv. I tried many steps as unplug the device, the key combination of power + volume down, also unplug the motherboard but didn't succeed. I know its not a hardware problem but VU Customer representative said we have to change the motherboard and some other components. Kindly suggest what should I do. I already tried many solutions, are given on the youtube or different sites but they are not working with my case. Kindly suggest me what should I do. Do reinstall TV software can fix it?
