30 seconds, then the picture comes back and light stays green for 30 seconds and I have a picture again for 30 seconds, then the light blinks green for 30 seconds and the screen is blank, (off) again. It will do this continuiously. I vacuumed the dust out, removed the lamp and put back, and the tv worked for a month and it started going blank again last night. Anyone with the same problem?
I have a similar problem. Just found out a possible solution yesterday. I am waiting for my lamp but here's what you need to do if you have replaced your lamp. Go into self diagnostics mode: Switch of your TV via remote, you will see red standy by light. Now,on the remote press "Display"=>"Channel 5"=>"Volume Up"=>"Power Button". All these keys need to be pressed within 3 seconds. You will now enter the diagnostics mode. Press "Jump" on remote (bottom right) 3 times and then press "Channel 2" 9 times. The screen will display your current lamp hours used.
In order to reset your tv to factory settings and for the new bulb to work you must reset this timer or else your TV will assume you are still using the old bulb and will automatically kick in "over protection mode". So here's what you do once you do on the lamp hours display screen. Press the "Channel 3" button on the remote 3 times then "Mute" then "Press Enter" to reset the timer to zero. Your TV should now work as normal. And remember, whenever a part is replaced all factory settings must be reset to zero. To do this, follow "Display"=>"Channel 5"=>"Volume Up"=> "Power Up" to enter service mode. Finally, press "Channel 8" and then "Enter" to put the TV back to factory settings.
The above mentioned is usually performed by a service technician and they charge somewhere around $95 diagnostic fee. You just saved this charge. If you see flashing red lights count them when they flash in sequence. This is a code for the techs to tell them what is wrong. These flashing red lights sequentially flash from 0 to 10 times to identify a problem. Usually, when the bbulb goes bad the only thing that might need to be replaced would be a "lamp Driver" aka "Power Block Assembly" $116.25 online from Sony, or the ballast. Sometimes, if you do not have a video a Thermal FUse can go bad which only costs $4.80 for the KDF60-XS955 but the techs will charge you over $300. You can do this yourself if you can get your hands on a service manual.
Hope this info helps.
Good Luck to you all.
Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.

I have the same problem. Its very frustrating to have spent over $4000 on a tv less than 3 yrs ago that doesn't work! I saw a similar problem posted for a different sony grand wega and their solution was to change the lamp. I haven't heard back from them if it works now, or not. PLEASE keep me posted.
I have the same problem with my set. It just started and I was looking for answers on options for repair before calling for service. Did you get this fixed.
03/07/09 Just got home from the movies and started to watch Pearl Harbor when my tv screen went black. The green power/standby light flashes for about 20 to 30 seconds then the picture comes back for about the same amount of time, then back to black and keeps repeating this patern. I just got on the internet to find out what is happening and found that the same thing has happend to many others but I still haven't found a solution and have not contacted sony direct. I am going to try unplugging the tv and plugging it back in. Someone said that worked for about a month but didn't fix the problem from happening again.
I have the same problem and used the diag instructions to find out my bulb had over 8000 hrs. Will order a new bulb.
Thanks a bunch!!!
Someone told me its a DC FAN
Is anyone have any idea ?
Thank you
have you tried reseting the tv by unpluging it for a minute, and then plugging it back in ?
