Mitsubishi has offices in Brazil. Apparently, they are out of the consumer TV and consumer entertainment business for a number of years now.

With the phasing out of CRT television sets, I have my doubts you will find a flyback unless you can find a scrap TV of the same model as yours. You can also try eBay or others like that to see if you can find this part.

It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.

The dark picture is a bad capacitor for the screen or drive voltage for the picture tube driver transistors. The other problem of streaking is one of the same. Thats the indication that a capacitors defective . It could in a rare cas ebe a defective or gassy crt as well but 99% of the time when a crt is said to be gassy its nothing more then poor drive to the crt. Good luck

Is yours fitted with a fuse in the wall plug? Replace that and see if that fixes the issue. Often the checking the simple stuff first saves you a lot of money.

Hello There!!!!!!
Well this is gonna take some work... First thing to start with is...

When you replace the bulb/s -does the bulb actually illuminate?

If you shine a very bright light into the surface of the screen can you see a faint image of whats on the set?

Do you get sound?

If the bulb is illuminating, is it blowing soon after?

Did the set return to normal operation after replacing the bulb the first time?

Side Note-Never touch a high power bulb glass enclosure because you can leave oils and moister that lesson the life of the bulb or make it more prone to blowing. I have no facts to support this note beside my own experiences but this is a known "thing".
Questions? Just ask. Mr.Mike

Several problems may cause your Mitsubishi television to shut off by itself. ... Plug the television in, replace the fuse or reset the circuit breaker as needed. If the light is blinking green, a power surge or unusual digital signal was detected by the television. To prevent damage, the television shut itself off.
