Have you reset the lamp timer? viewtopic.php?f=10&t=1050&start=0&hilit=Loading+Factory
Have you cleand the inside of the TV in the las 6 months? Have you closed the lamp door before turning the TV on?

Crowell

To be honest everything in the light engine has to do with the alignment of the picture projected on the screen. It might be the adjustment ring around the projector lens, or it could be a mirror inside, or something else. I suggest you either send it to a technician you trust so he can have a look ...

Crowell

Wow it looks like its either the digital video board or the DMD, how ever try to bring up the TV menu, if the menu is also affected, then it’s the DMD board, if not then check your digital video board for any swollen capacitors.

Crowell

That sounds more like the color wheel; you see after some considerable use the color wheel starts get stuck or the baring in the middle starts to move. That’s what produces the humming sound. Now when the DMD board (the brain of the TV) detects an anomaly (not reaching its 7200 rpm) it will shut off...

Crowell

Coincidence? My advice is that you start saving for the digital board, because sooner or later the picture distortion will probably return. If it dose, now you know why. Good thing tough that its now working like a charm.

Crowell

Is the “stand by/temp” sign show up just when you access the lamp timer option, or ever when your watching tv? A quick fix is to reset the lamp timer to 0. Here is a link of one of my earlier post http://www.fixyourdlp.com/forum/viewtopic.php?f=10&t=1050&start=0&hilit=Loading+Factory Goo...

Crowell

Hmmmm, first inspect the digital board for any swollen capacitors, if you find any replace them or buy a new board. How ever there is a strong possibility it’s the DMD since you can’t bring up the tv menu.

Crowell

Do you hear any strange noises coming from the back of the tv? Have you cleaned the inside of the tv free of dust & mold? Also check your video board for any swollen capacitors. If there are any you either must replace them or buy a new board.

Crowell

Ok here is a link to one of my previous posts where it explains how to reset the lamp timer.

Good luck.

Crowell

The lamp timer is a small program that keeps track of the hours that the lamp is in use. Some time the tv wont turn on after replacing the lamp because the DMD detects that the lamp hours exceeds the limit. So for security measures it doesn’t allow the tv to turn on. Here are the instructions of how...

Crowell

Just make sure you find out what type of color wheel you have, it’s either the silver or the gold one. Otherwise it won’t fit or work properly.
Here is a list of websites that you might be able to find it.

First of all how long ago did you buy your tv? Have you ever replaced the lamp? Have you clean the inside of your tv in the last 6 moths? Do you hear any strange noises coming from the back of the TV, other than the turning off randomly is there anything wrong with the TV?

Crowell

The first step you can take (and the cheapest one) is to clean the inside of the TV with a can of compressed air & a vacuum cleaner. If that doesn’t work then you should try to replace the ballast, since when it makes a clicking sound that means that it doesn’t have the voltage to light up the l...

Crowell

Try to bring up the menu screen, if it looks perfect then we can discard the DMD board, so all that’s left is the video board & the color wheel, do you hear any weird noises coming from the back of your TV? When you hook up another component device (red, yellow & white cables) do you get the...

Crowell

I think it was the cleaning, in some TVs disconnecting the tv for long periods resets the settings (even the lamp timer) although its very rear.
Glad I could be of help.

Crowell

My first recommendation is to open up the Tv and completely cleaning the inside especially the fans and color wheel. If that doesn’t work then the color wheel is my next suspect, the previous owner probably installed a second hand wheel, one that still works but is on its last days of use.

Crowell

Ok, let me explain from the top, the video board is divided in two. Analog & digital, if the menu shows up perfectly then it’s the digital board that’s sending erroneous signals to the DMD board, thus producing the green picture. You’ll have to replace it. Here is a video so you can have an idea...

Crowell

It sounds as if your color wheel has a air bearing issue, its very common problem, it causes the color wheel to not spit at the 7600 rpm that the DMD board requires to operate the TV perfectly.

Crowell

Hmmmm, looks like the only other option left is the color wheel, since some of the symptoms at the start point to the color wheel. You see the color wheel has to spin at approximately 7600 rmp, if the DMD board detects an abnormal spin rate it will shut off the DMD.

Crowell

My recommendation is first clean the fans on the inside of the lamp (you got to take the back of the tv off), normally the dust and mold that accumulates and tends to over heat the lamp. If that doesn’t work then go for the ballast, I would leave the power supply at the third place because you are s...

Crowell

That is a hardware issue, you’ll have to align the internal mirrors, personally I suggest either have a technician you trust have a look at it to see if it’s fixable, or just buy a new light engine.

Crowell

Correct, there might be a problem with the light tunnel; possibly one of the internal mirrors is misplaced.

Crowell

I think it’s the video board, check it for any swollen capacitors, they tend to blow up at the top, if there are no visible damaged capacitors then its probably an internal issue and you’ll have to replace it entirely.

Crowell

That sounds like the DMD or the digital board. Try to bring up the Menu with the remote, if you can see the tv menu perfectly then it’s the digital board, otherwise it’s the video board.

Crowell

Hmmmm, I beg to differ. Do you hear a constant clicking when the tv is trying to turn on? If you do then its probably the ballast. How ever if there are no other symptoms there is two other possible issues, you se the DMD board (the brain of the computer) is either failing and receiving erroneous re...

Questions
Do you hear any strange noises coming from the back of the TV?
How long ago did you buy your TV?
Have you ever replaced the lamp? (If yes how long ago)
Have you cleaned the inside of your tv in the last 6 months?
When you bring up the TV menu do you see it perfectly?

Crowell

WOW, 6 years with the same lamp! That a record. You definitely need to replace the lamp, how ever that noise that you hear is it a constant clicking sound, if yes then the ballast might also needs replacing.

Crowell

Hmmmmmm… interesting, ok, here come the questions. Do you hear any strange noises coming from the back of the TV? How long ago did you buy the TV? Have you cleaned the inside of the TV in the last 6 moths? Can you see the TV menu perfectly when activated from the remote? Also try hooking up a DVD, V...

Crowell

Wow either that technician has psychic powers or he’s a total lazy fraud. Let’s start with the basics, are those lines appearing when you watch TV? (cable, dish or air). How about when you hook up a Blue ray, new game counsel? (HDMI or digital device) Do they also show up when you connect a older DV...

Crowell

Ok, that confirms it, it’s the analog board, you see the video board is divided in two sections, analog and digital, it receives all external signals from outside devices, if just the analog input is having those lines then probably the analog circuit is failing, you’ll have to replace it. See for y...

Crowell

Did you reset the lamp timer?
viewtopic.php?f=10&t=1050&hilit=Loading+Factory

Crowell

Definitely the DMD board. Ok, now you need to open your Tv and replace the DMD board, look for the part number printed on the actual board ( like this “P / N : XXXXXX”) then buy it and have a technician install it. Be warn, do your homework and learn about the DMD, so when you go with the technician...

Crowell

Sound like the digital board or the DMD. To be sure turn on your TV (until the diagonal lines appear) and press the menu button, if the menu appears normal and with out problems then I suggest you check the digital board (if you see any swollen capacitors replace them, if not then in might be the a ...

Crowell

Don’t worry; nothing will be damaged, just spray and vacuum from a distance. Good luck.

Crowell

Hmmm can you describe in some more detail? Like… the lines only appear when you connect something to the analog inputs? Have you hooked up a HDMI or computer component to the TV? Can you take a picture of the lines or describe them more.

Crowell

The ballast is like a voltage amplifier that gets power from the power supply and regulates that energy to the lamp. If you hear a constant clicking (2 or more times) then its very probable it’s the ballast, how ever before buying anything first clean the Tv, take the entire back off, get a can of c...

Crowell

Whoa, lets back up little bit. Lets start with the TVs symptoms. How long ago did you purchase your TV? Have you replace the lamp before? If yes, how long ago? Have you ever had maintenance done to the TV in the last 6 months? Do you hear any strange noises coming from the back of the TV? Some times...

Crowell

Interesting, do you hear any clicking noises when you try tu turn the tv on? Have you cleaned the inside of the tv? (Dust & mold that accumulates with time)
As for you question, the ballast is the board in charge of sending voltage to the lamp from the power supply.

Crowell

Here is a useful video, go to minute 1:01 http://www.youtube.com/user/FixYourDLPc ... jr_9A5Xd2Q good luck.

Crowell

Ok, the basics.
Do you hear any noises from the back of the TV? Did you close the lamp door when trying to turn the tv on? Did you clean the inside of the tv free of dust & mold?
Also could you take a photo of the cable and the damaged pins? Maybe I can help.

Crowell

You’ll have to buy a new one, there is no way around it, if you try to tape it or fix it with super glue it wont work, since the color wheel spins very fast (5,600 rmp aprox).
Search for it by part number, usually it start with a BP.

Crowell

Yup, Color wheel and / or Digital board, we can rule out the DMD since you can see the menu perfectly. Check the digital board for any swollen capacitors at the top. You’re probably looking at around $130 (parts only).

Crowell

Let’s start with the basics.
Do you hear any weird noses coming from the back of the TV? Do you hear audio from the TV? Have you rest the lamp timer? Have you clean the inside of the Tv free from dust & mold?

Crowell

That was probably it (you see the dust & mold that accumulates tends to over heat the internal parts thus activating the temperature sensors, then the DMD shuts of the TV) best of luck!

Crowell

Here is how it works, when the lamp timer reaches or exceeds a certain amount of hours the DMD will shut down the TV for security reasons, when you install a new lamp and don’t reset the lamp timer it will keep doing the same thing since the DMD thinks it still has the old lamp (this is a VERY conme...

Crowell

Ok, its one of two things, see if you can bring up the tv menu with your remote, if the menu is distorted or not showing then it’s the DMD board (the brain of your tv) if you do see the menu perfectly then it’s the digital board, probably a swollen capacitor. Good luck.

Crowell

To be honest, for that model its very difficult to get to that fan, you would need to un mount the light engine, my recommendation is that you use a can of compressed air (the one used to clean computers) and a vacuumed cleaner (a hand held if possible), aim the can at the fan and at the same time u...

Crowell

Here are the instructions to reset the lamp timer, good luck. * Unplug your TV Set, wait for 5 seconds and plug it back. * With the TV powered off point your remote towards your TV set. * Press: Mute + 1 + 8 + 2 + Power. * Your TV set should now say “Loading Factory” * Browse down to “Option” then p...
