Question about Samsung HP-R5072 50 in. Plasma HDTV

1 Answer

Tv powers itself on and off

I've had the set since Christmas and this problem just started. After a variable length of time, the set will power itself off and then back on. The routine lasts about 10 seconds and once it begins, it will continue every 5-8 minutes. I have done a reset, unplugged the power for an hour and taken the batteries out of the remote trying to pinpoint and clear the problem. Any ideas out there? The set does feel warm to hot on the back panel...but I'm not sure what the standard temp would be for the set while operating normally.

You have a problem internally caused by heating (set is on for a few minutes) and then cooling (set turns itself off for a few minutes). Most likely a "cold solder joint" or a bad component on the power supply board. Locating it yourself can be difficult. If still under warentee you'll need to take it in or have them come out. (whatever is in your contract) They'll simply replace a circuit board instead of trying to fix it.

    As far as opertating internal temps go, around 140-160F. Some run lower, some run much higher, depends on how smart the design team was. Componets don't last a long time under high temps. A bad solder job can actually raise the temp sometimes because of higher electrical resistanace in the circuit. Your problem: Circut gets hot, breaks contact, gets cold, reconnects contact.

Emerson TV Model #LC401EM2F Fix after lightning?


Lightning damage on LCD TV's can be a doozie. You really need to get it checked out by a qualified technician. I've repaired several TV's hit by lightning, most of the time the damage was limited to the power supply board. However, it is possible that multiple boards were damaged. If multiple boards were damaged, it's not worth repairing the set.

Seems like your set now has a poltergeist in it after all these years. If set turns on an doff by itself and works erratically there could be a power supply issue since it supplies the juice for the various areas to do their thing. If PS is messing up, so will other sections of your set.

Goodmans 15" LCD keeps switching itself on


I'm having the same problem with the same TV that I bought my daughter for Christmas.

I haven't tried this myself yet, but it is suggested on another website that the TV is switching on to look for software updates during the night. Apparently you can switch the auto-update feature off, which fixes the issue.
