Why is screen not working? Red and green light both blinking?

Bad main

If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

The red blinking light can mean a couple of things. First, It could mean that you have a message. If that is not the case, you caould have on the 'LED Coverage Indicator'. The LED Coverage Indicator tells you by having the top light flash eather Green or Red depending on coverage. If you are in a place that has good coverage it wil flash Green but if you have little or no coverage the LED will flash Red. To check if you have this setting enabled, first go to "OPTIONS" on the phone in the full menu. Once there, go to "SCREEN AND KEYBOARD". Click on 'SCREEN AND KEYBOARD" and scroll down will you see the option that says "LED COVERAGE INDICATOR". Click on that and switch it to OFF if it is not already there. Then click the back bottton and click SAVE. That should work. If it doesnt, I would call your phone carrier and ask them.

Hi,
Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

Those blinks are fault codes. To know more visit the site linked here. http://electronicshelponline.blogspot.com/

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

Check the Lamp if no picture, audio may be present. Screen is completely dark. Lamp LED flashes 2X every 5 seconds, Power LED flashes GREEN for 140 seconds then flashes RED.
Check the ballast if no picture, audio may be present. Screen is completely dark. Lamp LED flashes 3X every 5 seconds, Power LED flashes GREEN for 140 seconds then flashes RED.

Be sure its blinking 5 times, count after it cycles the first time through the red lights. If it is fact 5 times, that is a lamp driver error.More likely it cycled 4 times, which is common on this model, if that's the case, then it's the fan. Most likely the large one in the rear...It's an easy fix, just pull the back off and replace the part.

Does the red light blink in a discernible pattern? How many times does it flash or blink?

42 inch Toshiba DLP. Was watching a movie and the screen went dark. The red light started to flash and kept flashing. any ideas
