I suggest you buy the bare lamp, the ballast & the color wheel on your own (remember to order them by part number) to save some money, remember to get the part number of both ballast & color wheel from the actual part, and then find a reliable & honest technician so he can install them, ...

Mmmmm, DMD? I would disagree, in picture no. 2 the tv menu looks unaffected by the vertical lines, so the DMD is fine, in this case it would be the digital board that probably has some swollen capacitors or something else wrong.

Crowell

Can you describe more the symptoms that the tv has, like do you get any sound? Can you see the tv menu? Dose your tv turn and then shut off? Dose it make any noise from the back of the tv? When did you buy your tv?

Crowell

Could you describe little more, like do you get sound? Can you see the tv menu? Dose your tv turn on then shut off? Dose it make any noise from the back of the tv? How long ago did you buy it?

Crowell

Have you cleaned the inside of the TV in the last 6 months? Normally dust & mold accumulates inside, and from the sound of it the light engine’s mirrors are clogged up. Try using a can of compress air and tell me if it works out for you.

There are two ways a lamp expires, one is when the picture on the tv starts to get dimmer & dimmer, until you only hear audio, then it shuts off completely. The other is when the lamp implodes & since it stops working immediately the lamp sensor detects an anomaly to the DMD board and shuts ...

You might want to check here http://www.discount-merchant.com/ just type in “Panasonic cable connector set” and search for your tv model.

Here is one way of reseting your lamp timer, hope it works.
press recall and Volume- till solid screen shows, then hit recall till you see codes on top left, then hold volume- and mute(same time) till all codes return to 000000000000.
Good luck.

Normally when the ballast start to fail it makes a constant clicking noise, another symptom is that you install a new lamp; it doesn’t have the wattage to turn it on. There is no simple way to test the ballast; you would need take it out of the tv and have a special volt meter checking all of the vo...

Hmmmm, that’s strange, the symptoms that you are describing are from a light engine but you say that some channels look perfectly fine, that shifts my attention to the DMD board that’s starting to fail (the DMD board acts like the brain of the Tv that controls the light engine to produce a picture o...

Crowell

The best way to do that is by looking at the part number (not the tv model) that you want know if its compatible with other tv models on the web.

Crowell

Negative, I don’t think it’s the power supply, if it was you wouldn’t get any picture at all, check the digital board for any swollen capacitors at the top and replace them, if not then buy a new one and replace the entire board, good luck.

Crowell

Did you already reset the lamp timer? Because if you already did then I would also go for the ballast, do you hear more than two clicks? If so then that second my premonition. here are the instructions to reset lamp timer: * Unplug your TV Set, wait for 5 seconds and plug it back. * With the TV powe...

Crowell

That’s definitely a color wheel problem. That high pitch sound is probably the bearing that’s worn out, you see in these TVs there are sensors all around and if one component fails that the whole TV shuts off for security measures. My suggestion is you first buy a new color wheel (its either the gol...

Crowell

Ok az240z. It sound like you have a expired lamp, these lamps commonly go out in two ways, one is when the lamp explodes (you hear a loud pop and the TV goes black), and the other is when the lamps starts to fade in intensity until you cant see the picture (like in your case). As for the other compo...

Crowell

Sounds like the digital board, could you be a little more specific or can you take a picture of what it looks like so we can be sure.

Crowell

Hello, let me see if I can help, first of all, how old is your TV? Have you ever replaced the lamp? The symptoms you are describing are from a failing color wheel (the buzzing sound) how ever if you never replace the lamp and is more that two years old then the lamp is not so far behind from expirin...

Crowell

The light engine is a very delicate and complex part; it’s composed of mirrors and or a prism. So it’s very, very difficult to repair, my advice is to replace the color wheel, and if that pink shade still remains then its definitely the light engine.

Crowell

Hmmmm, Mitsubishi TV’s have a reputation of swollen capacitors on the video board, have you check them physically?
If the capacitors have a round top instead of a flat one, then you need to replace them, otherwise you will have to buy a new board.

Crowell

Ok, first of all did you close the lamp door completely? If you answered yes, when you try and turn on your TV do you hear any strange noises coming from the back of the TV? Have you serviced your TV in the last 6 months (cleaned it from the inside free of dust and mold)? Im also suspecting that it’...

Crowell

Do you have the TV model? maybe i can help.

Crowell

Did you reset your lamp timer when you installed your new lamp?
Also, did you close the lamp door when you try to turn the TV on?
Have you cleaned the entire back of the TV free of dust and mold?
If you answer yes to all of these questions then im stomped.
Otherwise you should try them all.

Crowell

Forgot to mention the lamp timer, have you already reset it? (just in case the cleaning doesn’t work for you).

Crowell

Just to clear thing up, a DMD board is the one that controls the image projected on the TV screen (it acts like the brain of the TV), when a TV has white spots of any kind that means that its past its life span, either by a burned circuit or a capacitor. It’s a lot easier to buy one that to physical...

Crowell

OK, let’s start from the beginning.
First of all, dose your tv get any picture when you turn it on?
Do you get any audio?
Do you hear any strange noises coming from the back of the TV?
How long ago did you purchased your TV?
Have you ever replaced the lamp before?
If yes, how long ago?

Crowell

It's a very conmen issue that technicians forget or don’t know about the lamp timer, best buy has good technicians, how ever they are not exempt of human error, so it’s a considerable probability, here is a link of a video where it shows the inside of a Samsung TV very similar to yours (0:57 min). h...

Negative, the DMD board is like the brain of the TV, it controls the color, light and mirrors to produce the image on the TV (think of it as the President of your TV) and the video board interacts with all the external hardware connected to the TV and sends a signal to the DMD to project a picture o...

The best way (in my own experience) is to have the following tools. 1.- a can of compressed air. 2.- a small vacuum cleaner (preferably a hand held). 3.- a mouth cover. 4.- a pair of latex gloves. 5.- a Philips (cross tip) screw driver. Instructions. -Put mouth cover and gloves on. - remove the enti...

Crowell

That sounds like a DMD board going bad, but if you want to be more sure buy the entire light engine with the DMD included, if you already tried to connect all of the digital (HDMI, computer VGA) & analog (VCR, old DVD) inputs that we can rule out the video board.

Crowell

Yup, color wheel, another piece of advice, make sure you have a voltage regulator outlet connected between your Tv and the wall jack, just to rule out any voltage irregularities.
And last but not least, did you reset your lamp timer when you replace the lamp?

Crowell

First of all, when the TV still turns on, do you see anything wrong with the picture, like white spots, blobs, discoloration, ghostly images, etc? do you hear any strange noises coming from the back of the TV?, my first recommendation is to take the back of the Tv and completely clean out all the du...

Crowell

Have you tried resetting the lamp timer on the TV? This is a very common issue that many people take for granted or don’t know about. If that doesn’t work, that its definitely a tv part.

Crowell

Hmmm, that’s strange… its very obvious that you need to replace the light engine because of the cracks, how ever when you turn your TV on, do you get any discoloration or distorted picture, or is the image fine? Also have you reset the lamp timer after you replace the new lamp?

Crowell

Yup, Sounds like a ballast issue, how ever have you also tried resetting the lamp timer? That is a very common issue with Samsung tv’s, because the manual dose not include any indication of the necessity to reset the limp timer after installing a new lamp.

Hope it works.
