White dots on mitsubishi tv screen

i have 4 white dots on screen what can i do

I'm sorry to tell you, but if you have 4 white dots now, soon you'll have hundreds of white dots multiplying like rabbits. I just went through the same thing but with a happy ending. Here is a message I posted elsewhere.

I recently confronted the same "multiplying white dots" problem with my 65 inch Mitsubishi DLP TV. It seemed most repair shops expected nearly $1000 to replace the light engine (with labor) which is absurd since it would cost me just a little more than that to simply buy another brand new TV of the same size and more up to date with LED, etc.

But, with a little research, I found there is a specific chip (manufactured by Teas Instruments) inside the light engine which is the cause of the problem. Generally these chips are costing about $299-325 but I bought mine over E-Bay for about $260 (new) from a very reputable rated dealer there, after I found the part number for the exact replacement chip for my particular brand and model TV (some different brands may even use identical chips, but they all look very similar anyway, so make sure you know the correct part number.) I even found a YouTube video showing another person replacing their chip which was very helpful to me.

To make a long story short, after removing the rear of my TV, disconnecting a half dozen wiring harnesses and removing just as many screws, I slid out the light engine (metal chasis) and sat it on my kitchen table. Then, I had to remove a cover hiding the circuit board where the chip was mounted (this was more tedious with very small screws and a few more wires to disconnect). Once I exposed the chip (which was mounted on the underside of the circuit board) it was simple to remove the chip with one turn of a retainer screw and plug the new chip in with another turn of the retainer screw.

I then proceeded to put everything back together. The only mistake I made was trying to test the TV before I reinstalled the back of the TV in place, because there is a safety mechanism which prevents the TV from working without the back in place.

Anyway, in less than 2 hours, I had my TV working like new again and the picture looks awesome and I feel like I've almost got a brand new TV again! By the way, I since found out my bulb has over 8000 hours of use which according to most reports is way beyond what is normally expected, so also through an EBAY dealer, I have bought another light bulb (new) for about $55 which is very easy to replace on my TV without even removing the back of my TV, but I'm going to wait until my original bulb burns out, because right now, I just couldn't ask for a better picture.

I was a little hesitant initially about spending nearly $300 for a replacement chip, not knowing for sure if I'd save my TV, but looking back now, I'm sure glad I did, although I can't promise everyone would be as lucky.
