Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

3 Answers

No picture, won't turn off

I described my problem poorly the first time; I'll attempt to detail the symptoms more precisely here:
Power on, the middle light flashes and we get the normal start up bleep-bleep-bleep start-up sound; the middle light continues to flash for 30 seconds or so (sometimes during this time, there is a tone - high pitched noize. This is not everytime however). After the approx. 30 seconds, the set shuts itself off and then turns itself back on; I should say attempts to turn on - there is no picture; this repeats exactly 3 times and then on the fourth cycle, the start up bleep-bleep-bleep comes again and then all 3 lights flash (top 2 green lights and the bottom red light). At that point, the set can't be shut off. When we hit the power button, the cycle begins again with the single light (at time the tone) for 30 seconds 3 times. Obviously, we have to unplug the set to get this to stop. The only attempted fix thus far was a lamp replacement (we tried that as the 3 lights flashing is the bad lamp symptom indicator). I guess it's possible the replacement lamp we purchased came out of the box bad, but I find it unlikely and wanted to see if anybody knows a fix to this problem.

    I also have the same problem where unit can only be shut off by unplugging. Center light blinks. The only noise is a faint whirring that sounds like a fan. After about 8 min, the musical (3 tones) startup sound occurred, but no change to picture nor audio. We replaced the lamp a few months ago, so I'm pretty confident we do not have a lamp problem. The suggested solution by BIGTV is to replace the color wheel assembly or lamp ballast. It doesn't make sense to me that replacing those items would affect my ability to turn the tv off with the remote or on/off button. Can you provide additional comments?

    I have the exactly problem he described - very high pitch and very loud noise come from back. It sounds like from light bob area, may be the power supply close to it. The unit shut its self off very often, the frequency may related to the room temperature.

I worked for Toshiba America. All of these televisions are designed to fail after a reasonable time. They make way more money in the long run from parts and service then they do selling it in the first place. Is is this way with many technologies.

I don't have a suggested solution, as my 43" is on the fritz at the moment. But I can tell you a few things from my own experience. As noted elsewhere, if you have the "saw sound" (mine was more like a table saw or router), it's the color wheel. I replaced mine last year using the instructions at jangro.com. My most recent problem is that my set would attempt to start up (music), but the lamp would not light. If you either remove the rear cover (then you have to either tape or hold the interlock), you can actually watch and listen to the ballast try to light the lamp. On my set, it tries three times and then does some sort of reset, repeats this cycle two more times, and then I get all three lights on the front. When this happens the only thing that you can do is pull the plug and wait 30 seconds or so. It will not respond to the remote control or power switch. Since I have already replaced a lamp once (and my set has only about 6000 hrs on it), I thought it was the ballast. I replaced the ballast today, and still no joy. I think I am going to try one more lamp, and then this TV is going to become spare parts for someone...

Som-one,

the noise you hear after the melody would you describe it as like a buzz or a small chainsaw? If so you have a bad color wheel assembly. If the noise is intermittent than your issue could be the ballast that controls the lamp. If you've already changed the lamp the next step should be the ballast.

I have a broken Dell Precision 470 Workstation. The symptoms are as follows: Won't power up; Flashing yellow power LED on front panel; Blank STR_LED on motherboard; Yellow AUX_PWR LED on motherboa


Flashing front powerlight is often a result of a faulty powersupply, try another powersully on the pc and see if the problem gets solved. I've seen a few of these cases personally.

Fuse is fine and there is power at the wall........no stand by light or anything


Some receivers use what is called a switch mode supply. These supplies require that a circuit oscillate. Something as simple as a defective capacitor can prevent this from hapenning. This would cause the symptoms you describe. In order for us to really assist here, we need to know the make and model of the unit. Please update this and we should be able to provide more details and a more precise solution.

Thanks,
Dan

Mitsubishi WD-82738 has no picture, makes short whirring sounds but won't turn on. Flashes 6 red lights then 1 yellow light and repeats sequence. Tried system reset but to no avail, light turns green...


After rereading the symptoms you descibe what you describe might be a faulty colorwheel. When the set is first plug up there is a small mechanal motor that has to reach certain speed. if this does not reach that speed the set will not allow the lamp to fire. The whirring sound could be the colorwheel trying to spin up. these break all the time. (its a motor and anything that moves eventally will not.) it a fairly simple rep;air thatn most quilfied techs can repair. Such a repair generally should take more than a hour to do

Won't turn on . The red power button is just flashing.


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

FIne art scanning - uneven color across scans especially at edge of bed


The problem is going to be with the bulb itself. The scaner you are using is not made to do such precise work. The bulb itself is undersized for such a large scale job. You can look into upgrading the bulb of your scanner but I would not sudgest it unless you go to an authorized dealer/maint contractor for your Microtek to find the proper upgrade.

Blue streaks across picture


Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?
