52 HD Samsung tv turns off

We have a 2 year  old 52" HD that after a few minutes turns off by itself. This happens repeatedly. It takes a few seconds until we can turn it back on.

I have the same problem with my 56" HD Samsung. It shuts off automatically and then on the power button the word Lamp is light up in green. Sometimes I can turn it back on but other times it won't and I have to wait a bit. It's been embarassing a couple times when people were over for a movie. I believe it might be some kind of overheating problem but would like someone to confirm this.

Samsung TV turns itself off every 10/15 minutes


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Tv goes blank


The effect you described sounds a lot like a failed solder joint.

There are points on the circuit board that are subjected to heating and cooling each time the set is powered up, then down.
The solder joints near these areas can fail from metal fatigue as will any metal that is forced to expand and contract repeatedly.
These fractures are minute and can often only be seen under magnification.
Once found, they are simple to fix; removal of the old solder and resoldering will restore electrical contact in seconds.

If you can find a gray-haired tech nearby who is retired, maybe early since repair is a business stagnated by cheap labor in Asia, he/she will know where these areas are and can robably get rid of your lottery-like operation.
Or, if you have way too much time on your hands and are willing to buy a decent soldering iron and dig into the guts of your set, you can probably find the problem yourself.

While semiconductors do fail (sometimes for the same reason), since the set does sometimes restore itself, it isn't likely that any of those has died.

I would be torn to toss the set if it is otherwise OK for the simple reason that if repaired, it may outlast 80% of those bought in the last 2 years.
It is amazing the number of problems that are happening on new, sophisticated sets and it is traceable to lousy quality in parts and assembly.
I have one LCD set I will probably junk this year that is only 2 years old, flawed when I bought it new, and has a failure producing a vertical black stripe that would require replacment of the $4-500 panel.
Junk - Specifically, WALMART junk.

RCA will not turn on


I had this problem on My RCA tv, what I found was a couple of bad green capacitors in power suply there are around three of them I just replaced 2 of them if I am not mistaken one of them is C120 but if not change all three this are the value of the ones I replaced 2200uf 16v and 220uf 35v, if you see on top of the green capacitors you will notice they are bad.

My tv is working for more than a months and I had the same problem as you are having.
