TV made a loud crack or pop and the screen went black

Issue is either with the X or Y sustain board. Look for a cap that has blown or a cracked solid state device on the board. One of them is responsible for the ***** croak you heard.

Back light is not lit. Transformer died and no longer back lighting images on screen. New TV time.

3 times blink shows lamp cover is removed or not installed properly on TV.
Please take out lamp inside TV and check, seems its broken as you heard loud pop.
Thanks.

screen went black due to power supply failure. check also inverter.

Its the power cap mine did the same thing about 11 months into daily use

is there any led or small lights on front panel ... red green or flashing

I think that the pop you heard was an electrolytic capacitor blowing its top on the picture frame board. If you are able to check this for yourself by looking on the board for the one/s with a bulging top or are a brownish/black colour like something has caught fire. And also in this situation smell can be of great help as it will smell burnt out but PLEASE before putting your nose or anything else in the tv take all necessary precautions against electric shock and discharge any electrolytic capacitors in the vicinity. If you are not able to do this yourself find a competant technician. Hope this helps.
