Blue and pink dots displayed on screen

The DLP chip is failing. If it is still under warranty, contact the warranty section on Sanyo's web page.

I have the same problem. I have an LG lcd tv as well. I have my cable box connected to via hdmi into the reciever then from reciever to the tv via another hdmi cable. I can watch tv and like the problem above see the pink dots on boot-up but I can't get the home screen to display.

With the VGA you have a bad cable or a bad input jack. I would bet on the cable first. You are missing the green or the blue on the screen and that is why the red/pink is more pronounced now.

The issue is that the monitor in not getting the signal. This tells me that the video adapter ( or on board video) has went bad. Try another video card if all your doing is social media and surfing you can pick one up for around 20.00

Be sure your channel settings are correct and that you have proper orientation of the hook up cables. See if your remote has a video-mute if so turn it off...a video-mute will produce a blue or black screen. To be sure its not the tuner that's enter the menu screen if you can see the menu then the tuner is ok this means the down-stream video is functioning. Be sure to have all your input devices set to the correct output ports. If all check good and still blue screen then the logic section is not processing video codecs and needs servicing.

Could be try connecting to an external monitor using the vga port. If the same problem appears on the external display the problem is most likely the video card. You may wan to update the display drivers.

Main board issue.

there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

it sounds like the tuner went out,you would have to know how to solder and remove the old tuner to be able to do it yourself

your problem is the PIP board,tough to repair,can be taken out and replaced with two 10 mfd caps 50v bipolar from pin5 to 11 and from pin 7 to 9
