Sounds like you blew the horizontal transister in the CRT's high voltage circuit. It's common with tv's that are old or full of dust on the inside.

Samsung Big screen mod. HL-P6163W made load pop, then buzzing sound with screen going to black and white. Make buzzing sound and no picture when turned back on?


This set has a problem with the color wheel falling apart, which if one of the segments should fly off while the set was on it may sound like a loud pop, and the buzzing sound could be mechanical in nature with the wheel being off balance. If smoke appeared after the loud pop, then it could be a capacitor blowing in the power or video circuits. This model uses two different types of Color Wheel assemblies, either an L3 or a L6 and it would be listed on a white label on the Light Engines metal frame. Hope your solution is this easy.

Yes, loud pop sound was broken lamp in tv, replacement of lamp will fix tv problem.

Please buy Sony original lamp for good picture in tv.
Thanks.

Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...


It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.
