Will not turn on just keeps flashing red dot on center button

  • Andy May 30, 2012

    Will never buy a Samsung again! Crappy TVs and crappier service. Had a same problem a yr ago when TV started doing the restarts after 1 yr. Didn't bother to accept the service call as it was expensive $200+. Searched the Internet and figured it was a faulty motherboard...replaced the motherboard from one I got from eBay for $100 and the set worked for 1 yr...now after 1 yr , the same problem started again. I would think that spending $1600 on a tv should last you at least 3 yrs. The company does not make quality products. wonder who is in charge of quality assurance.

I've tried everything except replacing parts on a component level. I don't have a digital volt meter so cant measure what is working. Visually checked all the capacitors and it all looks good. Don't really want to replace the whole power supply cause everything is still good. What can I do, and if push comes to shove, where would i get a power supply from and what part number would it be.

Red dot flashing in speedometer dash of.my 2009 pt cruiser and would not turn on. What does the flashing red dot mean? Car finally started but red dot still appears when I go to start the car

The red dot is the immobilizer system. The control module needs to have a good "handshake" from the key in order to allow the car to start. If the key has gone bad or the control module then the engine will not start. Have you 2 keys? If so will the 2nd key start the car?

Self- reboots at start-up, then shows picture but with pink dots.

Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM811, CM812, CM817 & CS806; 1000ufd 25volts. It is the board to the left and you notice that the four cap tops are swollen.
It is easy to replace get a stanard solder pencil and you are in business.

Thanks for using FIXA, BIG IRISH.

Red dot finder scope

Simple-- you can also do this during the day on an object at least 100 yards away-- but at night; get the moon centered in the eyepiece and without moving the telescope center the red dot on the moon. This will get you almost aligned-- then put a bright star in the eyepiece and readjust the red dot to center the star.

BOSCH CERAN

The red dot light flashing indicates that you have activated the child safety option so the stove will not turn on. Hold your finger on the button for at least 4 seconds to turn off the safety option.
