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.

The very first thing you want to check is that the battery connections are clean and tight! If that does not solve your problem, check where the ground cable attaches to the engine. This does not sound like a starter problem, (that would be a long shot), so check other connections first. You might have the battery load tested... NOT just for voltage.

Sounds like the problem with the Crank or Cam sensors.

ours would do that i wont guarntee this will work but try using a different connection like we had a HDMI cord running to our cable box and one day it just went black so i unplugged the tv and still had the other componet wires hooked up to the box i thought it was the cable box so i tried another one and switched the input on my tv and it worked after a few days i could use the HDMI connection again not sure y but hopefully this is what your problem is.

Sounds Like the graphics chip is starting to go. Try CPR in NYC. They usually have a 1-3 day turnaround time, and are pretty cost effective. You can easily ship them your unit. They are faster and cheaper than Sony.

Sounds like your SNR is getting too high and causing the signal to overload. A few things can cause this a bad splitter that causes the signal to bleed and introduces noise, or a more common issue is having a weak signal coming from the cable provider and once it goes through a splitter it causes the signal to become to weak to be stable.

Since it sounds like your cable has been working up until recently, you may have had a cable or splitter go bad.

Call comcast and have a technician come out and test the line.

Check your battery cables, especially the ground cable. Check your ignition switch for loose wires/connections. Check your fuse box. Check your wiring harness for shorts and broken wires. When you say "battery seems to have plenty of power" what does that mean? What test(s) did you perform on it?

After days of frustration the real problem was with the cable box. It needed a firmware update. Following forum advice I disconnected the cable box power cord for a few minutes, reconnected it, allowed the cable box to reinitialize. Turned off receiver and TV. Turned TV back on and set it to HDMI connection, turned on receiver and all worked fine. Great picture and sound.( Needed to buy an optical cable to go from the cable box to the receiver to get sound from the speaker system. )--the dirtybird

I am not familar with that particular set, but this is what I would check (assuming you don't have a surround sound system hooked up to it as it would sound like a tuner problem otherwise). If you have external Audio/Video jacks with cables hooked up to the Direct TV box, move the video cable and see if you lose video when it is jiggled. If so, you either have a bad cable or connection/connector. When you say you have to turn the TV off for about 30 minutes, do you leave the directTV box on? If so, then the problem seems to be with the TV. Otherwise, maybe the direct TV box is at fault -- leave the TV on and turn off the cable box for a half hour and try it again. You have a few possibilities here, good luck.
