Overheating Have had this tv for over 2 yrs now and this is the first time this message has come up. "T.V. is overheating." in the bottom left hand corner. I know it's self explanitory but it has never happened before and now it happens after about 15 - 30 min. Any ideas?

    Thanks for the reply. I've had no internet for a while. The fan is working. I've noticed that the overheating only happens when it's hot outside. I just don't understand why that is a problem after 2 yrs.

    Thanks for the reply. As long as it's not a serious problem I'll just keep the A\C on.

There are contacts inside the Livingstation that make contact with the heat sensor on the bulb. If you take the bulb out you will see them in the upper right corner of the bulb housing in the TV. These can become corroded resulting in a poor connection between the TV and the bulb. A poor connection will make the TV think it's over heating even if it's not. There are 3 contacts in the TV and 3 on the bulb. Clean these contacts with a lint free cloth and some alcohol on both the TV and the bulb, being careful not to let your fingers touch the bulb. If your hands are too big to reach inside the TV, rub a pencil's eraser over the contacts to clean them. When putting the bulb back into the TV, seat as firmly as possible, then tighten the upper right screw first.

There is a fan in the lower rear. Check to be sure that the pair path is clear and that the fan is spinning.

    I would suspect the heat sensor transistor at this point. IT may be "noisy". Depending upon where the sensor actually is installed, the ambient heat may cause the circuit board to pull the sensor away from its heatsink causing premature detection and shutdown.

I know you posted this over a year ago, but I also have a Epson Livingstation with the same problem. In the manual it mentions how important it is to clean the vent located on the lower left, back part of the t.v. You need to clean it about once a month it says in the Manual.

Experiencing convergance problems in upper left hand corner on Samsung PCL541R mostly red shifted to right and down Bottom right half of screen is clear Do I need to replacer convergance chips?


projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

I get a message that the air flow/fan is blocked, then the tv shuts down. It's not blocked. It's perfectly clean.


This indicates the TV is overheating. Lamp based TVs usually have two or even three fans. One may be having problems or not turning fast enough.

Unit goes off after about 30 minutes, possible overheating ?


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9600826A.Have a blessed one!

Tv cuts off by it self. flashes message on bottom of screen check fan no. 2.


You haven't said which Samsung projector you have so I have to give you a generalised answer: The projector is overheating and going into protective mode.

Do as the message says: check the cooling fans as you won't know which one is fan no.2. Mostly it's simply the air filters which have clogged with dust and they're always easy to remove and clean. If you wash the filters they must be bone dry before you reinstall them.

Samsung DLP white spots


Are the spots fixed or do they move with the image? Verify that all venting is clean of dust. If the spots are fixed and upon close examination are a square shape, The device is overheating of failing. If the spots are moving with image it's a front end problem, and can be overheating as well.

3-d looking picture on top and bottom of screen


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
