It pops for awhile, then stops for about a week then it will go out completely. Place the tv in a corner for about a week turned off and then turn it back on, it will work again for awhile.

This could be caused by the high voltage transformer arcing or one of the anode leads arcing at the CRT cap. If you can monitor the back of the set open while in a dark room setting may show where the arcing is occuring
I hope this helps,

Heard a pop like a bulb blowing and can only get the sound. it makes a crackling noise when we turn it on.

It could have a arcing Hv Block or a something arcing on the Deflection Board. If the crackling noise is louder in the rear of the set, the Deflection Board is probably the cause. You can usually confirm by removing the lower back cabinet and observing the board on the left side. If you see any arcing at all, the board needs replacing. You can call Encompass Elect. for ordering the board at 1800-638-3328.
I hope this helps,

Tv went off and won't come back on.

the arcing sound is some kind of high voltage leak, which will shut down the tv. pull the speaker grill off and the access board, look at the 3 picture tubes, turn the set on you will see where the leak is, it's usually the high voltage splitter, which has a high voltage wire going into it and 3 high voltage wires coming out going to the picture tubes, if it arcs from the splitter you need to change it, if it arcs from one of the picture tube wires you need to pull the tube out and fix the high voltage leak, and possibly a cooling fluid leak caused it, not an easy reapir, you probably need a repairman.

Check the CRT socket of the tube that is arching. Could be a solder connection or shorted CRT. If you need further assistance let me know.

Arcing inside no picture

Most times arcing like this is from the Horiz. output transformer (flyback). The insulation has a break down and up to 30 KV will find the nearest path to ground. This would require a tech. to repair the unit. This repair will most likely cost around 250.00.
