Question about Samsung DLP HL-P5663W 56" TV

3 Answers

Dlp tv will not "fire up"

We have a Samsung 46" dlp model #hlr-4667wx. The unit is 18 months old. Powering up has, periodicaly, been "not quite right" since the unit was new. Symptom: the green lamp and timer lights come on immediately when power is turned on, warning "warble" will be very delayed (45 seconds). Sometimes the warble is heard several times before the picture appears. Occasionally, a high speed grating/vibrating sound is heard, especially after power is shut off.(color wheel?) Currently, only the green lamp light flashes on power up and the warning warble is repeated every 45 seconds or so, but no picture or sound occur. These "start attempts" can only be terminated by unplugging the unit from the wall. Other combinations of green and red blinking lights can be created by pressing and holding various buttons on the remote. Would bad colorwheel bearings cause this, or is it more likely the lamp, or something else entirely?

Hi there, your instruction manual should have a trouble shooting section, and will tell you what various warning lights are indicating (ie the Lamp/Temp lights will flash in a particular sequence), and will give you the probable cause. In some cases, it could be blocked vents (dust causing overheating/shutdown), or just the lamp failure or faulty switch (indicating loose cover).

If your tv is on warranty take it back to the supplier.the problem with your tv is in the power supply there is a open regulator in that circuit along with the H .O. Transistor there is a black that feeds from the HOT to the flyback which also needs to check probably it is also open.good luck my friend

It doesn't have a flyback or an HOT genius. It's a DLP.

Hi, I've been using my Samsung HLR 5087 DLP TV since 2004. Right now, if I turn on the power, the buttons light up as usual and the smiley face shows up on the small circle display. But the problem is...

take it to a repair shop for a proper diagnosis of the problem
the set uses very old technology and will be more expensive to run then the latest LED units
make the decision after you are acquainted with the repair costs and running costs of a new unit ( remembering that there is a warranty period with the new unit as well)

Poping sound last night now humming with no picture,unplugged tv due to not turning on/off normaly.HLR 61" DLP

It may cause by color wheel breaking off. Do not turn it on again, it will cost you more to repair. Call service for repair. If you can do it yourself, contact me I will tell you how to replace it. I can help repairing if you live in Orange county or Sandiego.

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.
