Well if your tv is older like the one in the pic it sounds like the bulb is overheating, you may want to vacuum the dust out of the back and make sure it isn't got block of air flow in the back and also make sure it isn't up against a heat source

Beware some technical handyman is necessary for you i think because of high voltage on some parts(inverterboard and mains), It could be some active components on the circuitboard that they can be badly soldered. try with a wooden object to manipulate some components on the circuitboard, a canister coldspray can sometimes also help to search loose or faltering components
SMD components or some bad capacitors, loose supression coils on inverterboards can even be happens.

Its very frustrating when we think we have something fixed and then forget to do something or hook something up wrong to only make what seemed like a simple repair much more complex...Here are a couple manuals if you don't have them that will help..Not sure if the last are the same as your TV but thought I would post them all in case they are...Good luck!

The power supply has been damaged I would think. Time for a repair.

There are a number of reasons this could happen and unfortunately not much that you can solve. If you have a backlight control in the menu you could try turning this down to see if the problem is reduced or cleared. This won't help you but the info may help a tech.
