Tv turns on but makes an electric cracking sound and shuts off another one turns on then the screen wigs out and turns off with the power light flashing

There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

hi make sure the lamp door is securely fitted has there is a safety switch, thanks

make claim on your home insurance

is it a tv or rear-projector? does it brings out the sound?

on a tv it could be the chromatisation IC that is defectiven when it goes blank. why? because of a power surge in the electrical net the tv got too much voltage to take.

try to desoldeer the EPROM IC and power on the set. does this make the set goes normal blue screen? if YES,you can order a new EPROM IC.

succes and enjoy

There is a small IC in the power supply section,
not the IC regulator that's the problem.

Well if it is DLP TV then crack/ pop sound was broken lamp in TV and if its another kind of TV as you did not mention its model and brand then have to check accordingly.

you need to replace the Eeprom location 1004

replaced flyback transformer

A convergence problem is very commond. In most cases the convergence output amplifer IC's need to be replaced. This is not something you should do. Call a repair shop.
