How do I fix my TV , turns off by itself and screen turns black after couple of minuets

Just replaced the lamp with a brand new original one ,, TV turns on fine , after about 2 minuets the screen goes black and sound remains on and the remote won't work, must be unplugged. leave it off for 2-3 minuets then turn it back on it does the same thing , and some times it keeps turning on and off by itself after the picture goes black. took the whole light unit out , cleaned everything including fans and made sure the color wheel is in good condition (and it is) no bearing noise or broken pieces and spins freely. also cleaned the lamp ballast. looking at the power supply board, nothing is burnt, all capacitors are good (non melted) . put all together and still having the same problem. So I got an external big standing 3 speed fan, set it to level 2 facing the (boards, lamp, color wheel) in the back , turned the TV on , worked good for an extended time (longer than before) maybe 5 minutes, so I switched the fan to speed 1 then the colors on the TV starting dimming until you couldn't see anything, still the remote won't shut it off , had to unplug it , so not sure what the problem is , need HELP please with the problem, so I can buy whatever part I need and watch TV again , thank you

SOURCE: I have fan#1 and Fan#2 message on screen.It won't

Check to make sure that both fans stay turning.If one stops prematurely, replace the one that stops. If they do turn until shutdown then try jumping the Temperature Sensor on the Lamp Housing. If that stops it from shutting down, replace the Sensor. If not , there is a chance you have a Actuator Board or a Digital Board causing the problem.
Hope this helps,

SOURCE: the tv picture goes out

Sounds like the ballast has gone out. Samsung recommends replacing the smps board(power supply board) when you replace the ballast because it is the smps that takes out the ballast. replacing just the ballast ,machine may work ok for a short time but will destroy the new ballast fairly quickly.

I have a sony kds-r50xbr1 and the problem is that it takes about 1 min to turn on and the screen appears for a bout 1-2 sec and then shuts off to a black screen where the power/standby blinks continuously...


Its time to replace lamp in this tv because existing lamp has reached to end of its working life span and causing problem. If lamp got broken, you will see lamp light lit on tv front but weaker lamp cause above symptoms.
Lamp replacement procedure is easy and written in user manual.
Buy Sony original lamp for good and bright picture in tv.

No picture.


Most likely you need a new projection lamp. The "strange sound" you hear is most likely the lamp trying to fire.After awhile, the set"gives up' and shuts down. There is a small door in the rear, and the lamp is behind this. It pulls out, after removing a couple of slotted screws. The bulb inside of the housing is what goes bad--the housing does NOT need to be replaced, unless you get an "original"(read:: more expensive) mits lamp.


But a "generic' is available to replace the bulb in the housing ,Probably a P22-150, or 180 lamp, about a $300 repair, if you have someone come out--or, if you are mechanically inclined, you could replace the bulb from the old housing(EASY to do), yourself, and save about half of that, or perhaps more.

TV shuts itself off after a couple minutes of being on.


One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.

I want to buy a second hand rear projection tv, around in 100 pounds is available in the market locally in london from private sellers i am worried about the lamp life, because its expensive to purchase...


an original lamp (original brand name of the tv) can be "alive" there for some years. if you want to buy a tv an suspect that the one is good or not just turn around that area one or a couple of weeks if still working with a great bright and crispy color is good symptom> (some re-manufacture lamps just work a couple of hours even new)
The lamp's life is a question mark in this technology (optimistic ingeniers (brands) count these hours as 1, 2 ,3, (thousand hours) (actually some manufactures count the time ""it is a simple timer the microprocessor can manage pretty well, but is not the mean of a good o bad lamp""
but i recommend my customers to have a spare lamp (just in case you are watching a beatles show) and blowns, you have it in the garage and (consulting the user manual) you change it a as regular bulb in your house.
But the lamp life "and this is the tip": (only two states)
  1. the picture tends to look dark or dimm (is logical because the high intensity the lamp works tends to create a tiny black surface on the heater and tends to consume more current and the answer is a dark picture as i told you already.
  2. the lamp blown (of course the tv cannot work and the LED "lamp" turns on or keep steady on the front panel with a complete dark screen.

50? Samsung DLP TV Model #HLR-5067W


Did you use an original replacement lamp or an aftermarket replacement? From the price you give, it sounds like an aftermarket lamp, which are notoriously buggy and the problem may be with the lamp. If not, the lamp driver is your next likely culprit. It is also called a lamp power supply or lamp ballast.

Tv turns off


Its the lamp that needs replacing. It will run for a couple of seconds and then it would dim or turn off.

model HLM507W as two different lamp replacement part. the LAMP for my TV was BP960224A. the replacement lamp listed on the Samsung site is BP960224C which was replaced by BP960224J. the difference according to my supplier is that A part has a brown power coupling and the J part has a black power coupling. hope this helps someone in the future. The couplings are different and a black LAMP coupling will not fit a brown TV coupling.

Replacement is simple, getting the right bulb is tougher. Make sure the TV is unplugged and the lamp has cooled. Looking at the TV from the back there is a lamp cover on the lower right. Remove the single screw, remove the door. There are two screws holding the lamp in, loosen these. Then flip the black plastic handle up at the bottom of the lamp assembly and pull the lamp assembly out.

Note the brand of the buld and the color of the connector (black or brown) and then call to order your parts from Samsung's parts reseller

With set off...mute + 1 + 8 + 2 + power.
Arrow down to "Options" push enter.
Lamp reset and lamp hours should be in there.
Power off 2 minutes or until fan kicks off to exit.
