Question about Samsung HLR5067WX 50" Rear Projection HDTV

1 Answer

SAMSUNG TV MODEL HLR5067W

TV SHUTS OFF AFTER 4HRS. OR COULD BE 15 MINS. BUT YOU CAN TURN IT BACK ON BY HITTING POWER SWITCH ONCE ???

I am having the same problem. The TV shuts down after a few minutes and I have to turn it back on. Then it shuts down a second time after a few minutes and I have to turn it back on yet again. Then it works fine.

The sales guy thought it may be the bulb so I ordered a new one to install but am not convinced that will fix the problem.

Any thoughts?

Sounds like the lamp to me. The projection lamps get hotter as they age and the TVs have a sensor to monitor the temp and shutdown the TV if it get too high
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to buy just the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. Really easy.

My tv comes on but shuts off after 5 to 10 mins. once it shuts off it won't turn back on for another 10-15 mins. What could be the issue


Sounds to me like a thermal problem. Could be the power supply overheating due to a faulty power supply or the unit pulling excessive current and causing the protection in the power supply to set. It could also be as simple as a bad solder joint or 'out of spec' voltages. These problems are unfortunately difficult to find as when the set is working, it's working fine. Running the set and poking around with a chop stick or similar can sometimes help as does a heat gun. Look for expanded electrolytic capacitors, especially around heat sinks. These procedures can sometimes at least point you to the right region for further investigation. Good luck. Cheers Bob

47pfl5704d/f7 shuts off


possibly a dry soldered joint, when the television gets warm the contact is broken as the soldered joint has become loose. it is an easy cure if you can discover the fault, basically resoldering the joint. but can be difficault to find. i have normally done this using a freeze spray(must be designed for electrical applications). spray the circuit board insmall areas. when the relevent part is rapidly cooled the contact will again be mmade and the television will work until the joint heats up again once it goes again spray again to check. switch off and re-solder

Sharp LC-32LE240M automatically shuts down


It should have come with a one year parts and labor warranty so consider looking into getting it fixed under the warranty--opening set or tampering inside would void the warranty.

Turn tv on watch it for 20 mins. screen shuts off but green power light is still on. turn it off manualy wait a few mins. turn back on watch for anouther 20 mins or so then screen shuts off again


The reasion your set is shutting off is because the power supply is dieding, and you need to replace the electrolytic caps on the power supply, or purchase a new one, go to www.partstore.com sand check to see if they have your power supply.

Battery indicator keeps fluctuating to 4hrs to 6hrs back to 4hrs then 8hrs every 5 mins or so i have acer A0532H with windows 7


first of all let me ask how old is the battery, if it`s new-discharge the battery until pc shuts down itself because of low battery, remove the battery , unplug AC charger from laptop, wait for 5 minutes, then hold power button for 5 full seconds, wait another 5 minutes, then put battery and ac charger on , don`t turn on laptop yet, wait until battery indicator shows that battery fully charged, then remove AC charger, and turn on laptop. P.S. you can try this on old battery too, but usually worthless, because old batteries are not recognizable by system currectly ..

TV shuts off after 15/20 mins!!


 Dear customer,
       It could be the transformer. The problem with protection circuit shut downs is you don't know which section is causing the trouble.  The protection system is really just a current sampler that when it detects an excessive current it opens up the power relay and shuts the power off.  And, as you indicated, unplugging for a few minutes will reset the protection detector.

But, there are about 8 or 10 sections within the tv and you don't know which section has the excessive current.   Most common causes are power supply, high voltage supply, deflection amplifiers or audio amplifier.  It usually takes a tech a few minutes to take some voltages and other checks to zero in on the culprit. Once the section is known then that tech can troubleshoot it for the bad component or shorted condition.
               Usually  it works fine until there is a signal coming in through the coaxial port. that is wen the tv gets switched off. Its a possibilty. Checking the  power supply unit of ur tv and see if it has malfunctioned and  check your power cable for starters.. 
Plz rate this solution.. thank you..
