SOURCE: Monitor goes black - green light stays on

My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.

  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

SOURCE: Picture on 15 year old Trintron comes on briefly then goes black

if the sound goes out its not a tube problem . a bad tube would have no effect on the sound .you problem (my guess) is in the power supply . a modern tv power supply has parts of it that stay on all the time unpluging it is not the problem its when you plug it in ! the power supply gets a JOLT . you might get away with it ,you might not . thats why we install surge arrestors on power plugs and with expensive tvs i recomend a UPS a power unit that keeps the tv powered even wnen the line power is out . thats keeps everthing in the sets nice and even ,so the tv lasts longer ... a modern tv turned off uses about 1.40 in electric a YEAR in standby mode , so what are you saveing if you send you set to the landfill early and have to buy a new one ? over 1.40 in electric ? . turn down you water heater or something else simple dont be blowing out you electronics for the sake of a few cents ..... good luck .... if this answer helped please rate a 3 or 4 , this high rateing will hepl keep me in the paid answer department . thank you

SOURCE: TV screen goes black, sometimes for hours

This model series had a odd problem that caused this. It was the Hoizonal wire connctors for the yoke. If my memory serves me right, the Yoke wire harness went from Yoke to Yoke and plugged in at the casing of each yoke. What I found is the solder connection on the small board of each Yoke was intermitent. Please be careful if you choose to tackle this. It is in a HV Area.
Hope this helps,

Have same problem. Not the proper fix though I found that taking the back off and heating it up with a heat gun for 30 seconds to 1 minute and tv works fine till you shut it off over night.Maybe someone can offer a solution with that in mind. Pretty strange

MY philips 42 inch plasma TV model 42pf3320/10 screen goes black after a few mins sometimes. what can i do to fix it???


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Screen lower half goes black/blank


The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.
