No picture T.V. turns on with sound but no picture. Red light blinks in intervals of 4.

Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.

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

How many times red light blinks when TV lost picture? There would be interval of 3 seconds in red light blinks so count pause to pause and let me know.

red light flashes 4 times then stays on for about 5 seconds then flashes 4 times again any idea what this means and how i can fix it tv is about 4 years old and only just started doing this

4 beeps & 4 flashes mean problem with the power supply. For my experience, most of the time the PSU is good, it is just overloaded.

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.

I think this sounds like my problem (need to replace the projector lamp). However, when I hit the "on" button, my SXRD 50" blinks green for about a minute then starts blinking red. Can you confirm the bulb solution? I was very pleased with this sight when my fan malfunctioned. I got the fan in a matter of day's from Sony and it fixed that problem.

What are the labels on the lights? Timer/Lamp/Service and what color is wich?

Is the red light flashing a code ? exaple 4 blinks pause 4 blinks ?
