Tv will go off on it's own and back on again in a few seconds . It makes a small popping noise when this happens. It is now windter and even putting a fan on it dows not help. When it comes back on I usually have to adjust the volume up or down - usually up

You could check to see if Samsung has a Firmware upgrade for this issue at their Consumer web site. Doubt it will fix your problem though. Are you using a wired LAN connection? If so then check it and make sure it is not loose, or that your router has not been powered off. If all checks good, or you are not using a wired LAN connection you will need to replace the main board. I can not give you a part number because you did not include your model number in your complaint. I hope this helps.
When my TV did this in the past it ended up being the color wheel. I had someone replace it and it worked fine. I asked it if had to be calibrated after it is installed and he said no. Also make sure the door switch is pushed down when you install the back bulb door. Sometimes this switch can go bad as well.
This means that the lamp for the tv has gone out. This is replaceable but it is in the $200-300 range plus labor. If it is under 2 years old it should still be covered under warranty for this problem.
Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
Unfortunately, we have the same problem. We hear popping and our sound goes lower. It is not the cable box for us, it's definitely the TV; however, it happens, on our set, after its been on for a few minutes and then goes away after half an hour or so -- however, this evening its been happening for the past hour and the TV has been on for the evening.
There are no tubes; generally the pop happens because of high voltage. It is being shorted out and the pop is either the flyback transformer or the horizontal transistor oscillator. these two are reponsible for creating the high voltage cycle for your television; when either of them or their circuitry is shorted out you hear that "pop" which is the emergency cut off circuitry coming into play to protect the rest of the television.
Our Sony (almost new) is experiencing sound problems. The sound go off and on about every 10 seconds. Cords appear correctly connected. It sounds as if its coming from the television. Can you help with this problem? Thanks,
A loud popping noise, like a sharp "snap!", is usually caused by high voltage arcing. Somewhere in the high voltage system an insulator may be cracked or loose, such as the plastic around the flyback transformer or one of the rubber cups on a picture tube. When the high voltage arcs, it momentarily drops and the picture could go out for a split second. High voltage is dangerous in projection sets so allow a qualified tech to service it for you.
