What is causing white vspots on my tv?


As you probably know, your DLP (Digital Light Processing) TV works by projecting Red, Blue and Green light from three LEDs or a color wheel depending on your model, onto the DLP chip which contains rows of thousands of tiny mirrors. These mirrors reflect the colored light through some lenses and other fixed mirrors and onto the back side of the big frosted plastic screen on the front of your TV cabinet. In the neutral position, these little mirrors don't reflect any light onto the back of the screen. If they flex into a certain position they will reflect any light from the three LEDS shining on them. What color depends on which LEDS are on at that moment. Each one of the mirrors is roughly equivalent to a pixel.


Any mechanical thing will eventually fail and if any of these mirrors fails in the OFF position, then no light will be projected to that mirror's target on the big screen. You are not likely to notice one "pixel" on your screen being dark though. However, if any of the mirrors fail stuck in the in the ON position they will continuously reflect all three LEDs light to that mirror's target on the big screen. This little white dot is noticeable and your attention will constantly be drawn to that stuck mirror's white spot. Once one mirror fails it is only a short time before more and more mirrors stick in the ON position and you see dozens then hundreds of white specs. It's VERY annoying.


Fortunately, if you are fairly DYI handy, it's not a big job to install a new DLP chip (or LEDs for that matter) into your DLP rear projection TV. Do a BING search on the internet for the make/model of your TV and something like "how to change the DLP chip" in that make and model. There are plenty of YouTube videos on line that make the procedure very clear. If after watching the video you don't understand the procedure, that's an indication that you shouldn't attempt it. I've replaced two LEDs and the DLP chip on my Samsung 65" TV. That might seem like a bad thing but if you consider that the TV was 7 years old at the time and these seem to be the only parts that fail, it was worth it to more or less make the TV like new again. When you search for the parts, watch out for sellers with low part price but ridiculously high shipping cost. I found that Sears.com had the best price and shipping times for these parts.

I need to find a replacement mirror for my Panasonic projection tv model number PT47WX49E. It's the big mirror in the back that reflects the image onto the front screen


There are a number of sites on the internet if you Google the model number and the word mirror that sell mirrors for these sets.

For a OEM part try ANDREWS ELECTRONICS who while in the LA area ships all over the nation. They are the largest OEM parts dealer in the United States.

Let me know if you have a question, I will help.

WHITE SPOTS


This is a DLP projection tv. In it the image is generated by reflecting the light from the bulb on a DMD chip - a chip with a million tiny mirror that are individually controlled. When a mirror no longer works it reflects constantly all the light it gets , so you end up with a white spot on the screen. This is unfixable, the entire DMD chip will have to be replaced at a great cost - the chip itself will cost you less than $200 but the install and adjust procedure is very complicated so an experienced repairman will ask you at least $250.

My mirror broke in a kdf-50we655 and i need to know what the size is so i can order it?


First off the mirror in your Sony is not a standard mirror. It's called a "front or first surface" mirror meaning the reflective surface is on top of the clear glass as compared to normal mirror which has the reflective coating behind the glass.The wrong glass will throw the focus off and reduce the brightness...how much I really can't say. Because of this cleaning the mirror is also very tricky...no alcohol or windex. Use an eyeglass lens type cleaning cloth with a light touch. As for the mirror size...try measuring the mirror mounting or "holding clips" area to determine the original size. Another trick may be to ask your local Sony repair center about the mirror size because they will most likely be your only source to order the correct replacement mirror.

Why the white spots on my tv screen. started with one, then two and now up to 9


the reason this is happening and the problem is getting worst is because the DMD board is starting to go bad some of the micro mirrors are getting stuck on the on or off position and the problem is only going to get worst if you want to fix this problem you need to replace the light engine here is a link that will teach you about this projection works

Mirrors going bad. White and black spots are apperaing on my screen. More each day. It is my understanding that tiny mirrors are not turning off or on. Purchased DLP 46'' Samsung January 2007


Well here's the scoop. White spots mean that the mirrors are stuck "on" reflecting light. Black spots mean that other mirrors are not actuating and are not reflecting light. In any case the DMD bs or the DMD chip needs to be replaced by a trained Samsung tech only.
The DMD bd controls the DMD chip.

Sounds like you need to clean the lenses and reflective area inside your set. It is easy and all you need is a screwdriver, windex and a paper towel. UNPLUG YOUR TV.   Take off your screen and screen protector and safely set them aside. 
Clean only the lenses ( glass part) and the reflective mirror type area on the top of the inside of your set.  It will look like new. You need to do this at least once a year.

You will need to contact a glass place to cut a new mirror that has the reflection paint on the outside of the glass instead of what most mirrors have them painted on the opposite side . Good luck
