Sony TV kds-60a3000 dull picture problem. I have the TV for about 2 years. Now when I turn the TV on, the picture looks fine. After, awhile(30min to hour) the picture suddenly got darker and dimmer. I don't think it is the lamp since I have it less then 2 years. Does anyone know why? Thanks,

3 blinks of Standby/power LED of Sony sets denotes a SMPS board [G-board] failure. . Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
the flashing light is more than likely the fault code. but those can be wrong bet even money that the door has a sensor to know if its open and the the bi-metallic switch is on the fritz look around the door see of the is a small pressure actuated switch the opens and closes with the door if so all else checks out 85 % chance that will be you problem
depends but for me a sony has a softer picture brightness so the parameters are contrast/picture 80, brightness 50,color 60,sharpness 40/20 try this charley
Hi,
Let your unit cool down for an hour, give proper ventilation and air flow. keep away all the obstruction from the vent, the processor has a built in thermal sensor that might be trigger by peak temp on the main board.
Hope it may help you.
Have a nice day.
Thanks for using Fixya.
Hi,It seems your ballast(board that powers light bulb) is going weak.The ballast was used to provide a lower voltage because lamp didn't use as much as brand new one. A newer one takes more voltage and when ballast doesn't provide as much power it will flicker or produce a dimmer image.I found the one for your tv here: http://www.discount-merchant.com/1091041-KDS-60A3000-p/1091041.htm?Click=48173 Good luck and God bless you!
