SOURCE: white dots on sumsung plasma tv

This is a problem is usually on your Y sustain board. There are two adjustments for this in which an Oscilloscope is nessesary for the alignment. However, there are two other things that can cause this also. This is beyond your abilities if your not a tech. Sorry for the news, It's not a major repair but should be done by a qualified tech.

The only thing you can try is to adjust the tiny control on the Y board, if you want to try do this. Open the set , set it up so you can watch it with the back off. now looking at the back on the left side you will see a circuit board larger connected to a smalled one or two that go to the screen edge . on the larger board look for a few small controls, mark their positions with a dark sharpy then turn each a little while looking at the dots to see if one makes them better or worse. If one control effects the dots try to center it for the least amount of dots, if no effect is observed when a control is turned return it the original position that you mark before starting. if the dots do not clear either the Y board is bad or the whole scfreen is defective.

My nevi 2595 shows only touch dot and will not do anything else. If you touch it the dot moves to another area on the screen


It looks like you are in the calibration mode ... just touch every dot and after a few times it will go back to the menu ... as usual.

Cracked screen & white dots appearing since the crack appeared


I have a Mitsubishi TV and had the same problem. There is a mirror that moves to control each pixel. When some of them fail to move you get the white dots. Google your problem and a company will come up(sorry forgot the name).,you can buy the new part from them and they have exact utube videos to help you do the repair. Took me about an hour. Part was around $150. Very rewarding feeling when you turn the tv back on with no white dots.Still dot free after two years

My mitsubishi 65in tv has a lot of small white dots on the screen what causes this?


projection tvs can display white dots from the dust that is on the reflector mirror your lamp shines the picture on before it is reflected onto the front screen of your tv, one must be very careful when cleaning this, may be worth a service man doing it for you

Touch screen not responsive after speaker replacement It worked before speaker replacement.


To calibrate the touchscreen on a nuvi 300 or 600 series:

1. Power the unit On.

2. From the Where to? / View map screen, touch Settings (wrench icon).

3. Touch Display.

4. Touch Recalibrate.

5. A new screen will display that says Press Dot.

6. Touch the center of the dot.

7. Keep touching the center of the dot as it moves around the screen.

8. When Calibration Complete appears on the screen, please touch OK.

The touch-screen will now be recalibrated.

Converge off a little and screen has green tint


If you have the remote, go to the setup screen and move the picture. Converge has nothing to do with where the picture sits but, where the red, blue & green dots land. All you should see are pure white dots. There should be absolutely NO color ghost anywhere on the screen. If so, you need a bar / dot generator to set the convergence to center the dots.

Try to calibrate the touch screen. Push and hold the power button on until you see a white dot on the screen. This is the calibration mode. Touch the dot and another dot will apppear, now touch this dot again, keep doing this until the unit reboot.

If you touch the 1st dot and nothing happens then the digitizer on the LCD is dead. If the unit is still under warranty, get a RMA and return it to Garmin.
