Samsung SP43T5HP unit keeps power cycling


A couple of nights ago while my parents were watchign TV the unit decided to switch off and then seem to go into a "power cycling" loop. They could not stop it using the remote, the only way was to either unplug it from the wall or use the power button on the unit itself.

I had a look yesterday and when I pressed the power button on the unit again it didn't go into standby mode, it actually tried to switch itself on, the "standby/timer/power" (it's the one light) light flashed red 5 times then on the 6th time it went green, I heard sound for a second with no picture, then the unit would start the power cycle loop again.

I took out the batteries out of the remote (just in case that was soemhow causing it) but that didn't help either. At this moment I have unplugged the unit from the wall and will re-plug it in after 24 hours to see if that helps.

the manual for the unit doesn't have any troubleshooting steps for light sequences, etc so I can't do much. I am guessing it is the lamp but I would have thought the tv would behave differently to this.

Does anybody know what's going on?

Re: Samsung SP43T5HP unit keeps power cycling

I had this problem in December...ultimately it was a problem with the digital board (the tech tried a new light engine first, but that didn't fix the issue). Pay attention to the lights on the front...but if the picture doesn't come up at all and the power just cycles, your issue may be bigger than just the lamp.

You must change the bulb. It is worn out.

TV doesnt turn on. It cycles thru a couple of times and then stops. 2 green lights and 1 red light flashing on front panel. replace lamp about a year ago

Check the filter and see if this is clogged. If so clean and reset. The processor of the projector seems to switch off power due a feedback error and must be traced.
If the lamp holder is loose fitting, if the lamp has failed or if there is problems in the power section this can trip.

Phillips 55" rear projection HD ready --power button lights up, but no picture or sound--just a clicking noise. Also, we can no longer adjust the blue convergence. The adjustment screen comes up, but we...

Got our tv in 2004 and we're having the exact same problem. When the blue convergence started going a couple months ago my husband researched the heck out of it and decided it would cost less to just replace the tv with a newer, nicer model rather than repair it. And now, as of last night, we are having the same power issue where the power button goes on, but won't stay on. It just clicks on and off and no sound or picture. Did you ever get yours fixed, or did you end up replacing?

I have a Samsung rear projection TV, model no SP61L2HX. When switched on and waiting for the lamp to warm up it switches off. Then it turns on again and keeps on repeating this cycle.

    According to the symptom this problem called hicking.And in this situation various components could be shorted.
   The main cause is power supply,Check the unit may be there could be capacitor leakage.Safty resistor could be open.
  If you can do it by yourself and expert then ok.But if you have no earlier experience then plz contact any expert nearby.
  Thanks for using fixya.

My 4 year old Magnavox 51" rear proj TV cycles ON/OFF every 5 sec

Hello bcd74071,

I would suspect that the shutdown circuit is triggering. Have you checked the HV anodes of the CRTs to see if the voltage is fluctuating? In addition I would check the Horizontal output transistor and the Power FET in the switching power supply. The fact that you removed the blue CRT and put it back and the problem seemed to go away points to a possible cold solder joint which could have this effect also. There are a number of things that could be wrong, Here is a list of some of them that you can check:

1) Faulty component on power supply board (check capacitors for problems)
2) Faulty connection on power supply board (check for cold solder joints)
3) Faulty component on Deflection of HV power supply board (check for bad capacitors, zener diodes, Horizontal Output Transistor, and Integrated High Voltage Ttransformer)
4) Faulty connection on HV power supply board (check for cold solder joints)
5) Faulty CRTs (check anode voltages, remove anodes from CRTs and see if the set remains on, if so check for shorts on the CRT socket board or using a CRT analyzer check for internal CRT shorts)

These items are but a starting place for you.

I hope this helps,

Thank you,

Samsung sam HLN507w model xixaa won't power on

I got frustrated with the tv and (after advice from a friend) banged on it somewhat gently with my hand. Now it turns on! My friend claims that their downstairs tv acts the same way and a few gentle taps do the trick every time. Go figure.

I'm not completely satisfied with this solution and don't think it will work forever, but so far so good.

T.V powers off

if that is a short for sure it will shut off permanently. probably a loose connection(cold solder). have it inspect physically and resolder if possible. good luck!
