Do you have multiple samsung remotes being used in the house by any chance?

Sometimes this type of problem is caused by the actual buttons used to turn the tv on. Because we tend to eat and drink while pushing buttons on the remote, we tend to get the remote dirty or wet. Blow some compressed air into the buttons of the remote first to see if that solves the problem. If not - then try blowing the compressed air into the buttons on the tv for power, etc.

Also, see if the problem persists after removing the battery from the remote.

Then try resetting your tv by unplugging it for several hours for all power connections.

The tv turns off by it self


Hi,
Your problem resides in two places, the A/V board and the main system control board assembly, as for the unit switching off and on this is an indication of a bad lamp, the unit has a lamp usuage timer that records the amount of time on the lamp, it needs replacing if it has been more or near two years as the lamp is only good for 6500 hrs of use, thats ruffly three years, The componet input not working is due to a bad switching IC on the A/V board, Replacing the Audio/Video board will solve the input problem. The A/v Board plugs into the main board assembly.

Apart from these the other possibilities are:-- 1)loose solder connections can cause short tracking. Get the board re-soldered to fix this issue. 2)faulty or bulged out capacitor causing short tracking.Get the faulty capacitor replaced to solve the problem. 3)the unit gets over heated internally and shuts itself.Keep distance between tv and wall and keep a desk fan behind the tv to keep it cool while you are using the tv and check. overheating can be because of internal fan problem.

Thank you!

Samsung hcm4216W turned off by itself loops.


Instead of typing model number of your TV (that located on right hand side and on the back of TV) you published here part number of your TV's remote control. LOL.
Anyway... If it is LCD/plasma panel that you talking about - than power supply have bad electrolytic capacitors that have to be replaced. You can recognize 'em by bulged/swollen tops (instead of flat tops of good capacitors).
This repair required soldering skills.

Tv keeps turning its self off


Many issues can cause this, there is no simple answer, but one common issue is the convergence circuit failing. The set will need repaired.

If you are handy with electronics you see if the convergence ic's are failing, usaly on these there is a short jumper connector from the right board to the middle board closest to you from the back, if you disconnect this connector from the back and the tv comes on it is a convergence ic problem. In this case you need to replace the ic's on the convergence board the two stk392 ic's plus check the resistor.

TV KEEPS TURNING OFF BY ITSELF


If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
