Replacement lamp for Samsung HLN437WXIXAA DLP TV

We've had out TV for several years and the picture seems very dark. We're thinking that it is time to replace the lamp and want to make sure we get the right one. We have the HLN437WXIXAA model and want to make sure that the lamp identified for the HLN437W will work....don't want to order it and then find it doesn't fit.

Also, someone told us that when we replace the lamp we should have someone tune up the mirrors....does that make sense?

If you hear a ticking and or buzzing sound as it is trying to start up then most likely the replacement lamp is bad. Take it out and reseat it one more time to see what happens. The noise you hear is the ballast attempting to fire the lamp up.

SOURCE: Samsung 50" DLP - Lamp Light Blinking after bulb replacement

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

My DLP lamp has been replaced but yet the picture is still dark. I have tried...

This thing you have do:

  1. Open the cover of your TV.
  2. Look at the CRT driver board inside and remove all screws including the cover of that board.
  3. Then rotate the CRT board in reverse position to apply a voltage data.
  4. Power on the TV to start a voltage data.Use a multimeter (range on DC) then place your black prob(-) to the ground of the TV and the other one is place on the B+ that usually found on the 3rd pin of the ply-back transformer.Check the B+ voltage if you have a 100-120vdc.
  5. I'm sure you have the B+ voltage because your TV is not totally dead.Check the reading of the B+ if it is flickering.
  6. If the B+ voltage is flickering and you hear a clicking sound,try to hang the connection of the B+ to the fly-back then look at the reading if still flickered or stable.If the reading is stable when the B+ connection is hang.You have to replace the ply-back because it is shorted.
  7. And finally after you replace the ply-back.Power it ON.
Thank you for reading my tips.

Turn set on picture is dark.. if I leave the TV on.. in several hours it's viewable.

I have seen several Samsung's including 3 that were only a few months old at the time where it was the lamp---one was so dim it was very hard to even see the picture or that the screen was lit.

Two suggestions here: One of course would be to buy and gamble and replace the lamp.

What I found in two of the three cases was when I removed the lamp the glass pillar inside it was "bent" at a angle from heat or a natural defect--in both those cases a new lamp cured this dim picture issue.

Set will monitor the lamp and if too dim may shut set off or even blink for a prolonged period of time.

If the lamp is over 2 years or age (average life) or was replaced with a non-Samsung lamp you are going to have to take the gamble to try another one.

Inspect the lamp---that pillar supports the filament and if bent the lamp is suspect at best.

I have a Sony Grand Wega KF-60WE610 television. It now seems that the picture is darker than it used to be. I can still watch a show, but many people who have seen my television comment on the poor...

I'm sorry that the pictures on the TV screen is black. Based on the information you have provided, it appears that the issue is with the Lamp itself. The lamp of the TV may have to be replaced within two to three years depends upon the amount of usage.
If the screen becomes dark, the color looks unsual or the LAMP indicator on the front of the LCD projection TV flashes, it is time to replace the lamp.
Thanks for understanding. Please let me know if you require further assistance in replacing the lamp of the TV.

My Sony Trinatron has suddenly displayed a dark screen on all channels. You can see the picture but looks like it's nightime. I've tried ajusting the brightness but no result.


does the TV bring out sound even as the screen display is dark?

Problem should be from the TV lamp/bulb. When a TV bulb/lamp is dying, it makes the pictire on the screen become dark and very hard to see.

Have the lamp replaced and hopefully, your screen should be perfect as before.

Let me know if you need directions in replacing the lamp, even though it is very simple replace.

Yours sincerely.

Color red seems to be more prominant...than other

I've had this problem with my projection TV recently. I would say your lens/lamp is to blame. It might be time to change it, depends on the last time it was changed, most of the time, the TV will tell you that it needs to be changed, but not always. I think your best bet is the TV lamp.

Dark picture!

The Lamp it self, the Ballast, or the Power Supply that powers the Ballast. Even a combination of the Lamp and Power Supply is a common problem. If you have not replaced the Lamp since you have owned the set I would replace that first. The Lamp has about a 3000 to 5000 hour life span.
Hope this helps,

No picture on my 62" DLP Mitsubishi

I am not sure what the problem is, but usually if a lamp is bad, the other 2 lamps will still function. Since you are getting no picture at all, I am thinking it is a circuit board problem. TV electronics are expected to last 3-5 years. After that, many components will start to go out one by one. If you have your tv repaired, I would replace the whole circuit boards instead of just the bad component. The power board is the #1 board I would replace 1st. This is the most stressed board and will cause most of your tv problems.

Picture seems to be alot darker than before. toshiba 62hm95

I just replaced a lamp in a Sony LCD projection that was just over a year old and it was bad. It was a VERY dim picture. You have a DLP but, in either case a dim or dark picture is almost always caused by the lamp.
