Samsung DLP has no sound for about 8 minutes when first turned on.

Mine does the same thing. It makes a regular popping sound that does not change in level with the volume control. When the popping starts getting erratic the pixelated sound starts and in a short time the sound straightens out for the rest of the viewing time. However, the next time the cycle repeats itself. Did you find a fix?

Akai model PT50DL24X/SMS when you turn on the set it makes a popping sound then there is no sound at all. the only way to get it back is to unplug it and let it reset.

the popping sound is generated in the audio output amplifier IC, change out the ic and any associated electrolytic capacitors this should restore normal operation good luck

It sounds like your high voltage block is arcing and causing the TV to go into protection shutdown temporarily. If that's the case, you'll most likely need to replace that HVB.
The other thing it could be if you're hearing "popping" (snapping ?), is that one of the CRTs could be arcing to ground, maybe the green one since you're getting too much green.
Good luck.

Toshiba HD made a popping sound and went out.

Check the lamp to see if it popped. Try replacing it. Also check the web for class action law suit for these sets, Toshiba has an extended warranty for lamps for certain units.

Might be a bad CRT, might be a bad focus block, I would refer you to a Repairman as it will take some experience to repair.

Possible problems: * The TV set may be unplugged. * A fuse or circuit breaker may be blown or switched off. * The remote control unit (RCU) may be disabled. Solutions: * Make sure the TV/VCR are plugged in and the wall switch is on. * Check the fuse or circuit breaker. Test the outlet with a lamp. * Replace the RCU's batteries: if this fails exchange the unit.
