Hi,

On Sony TV's the blink codes itself indicates the problem. 5 Blinks on your model refers to :-

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 slightly.


Now,

If you are handy with electronics and can solder and unsolder electronic components, you might be able to fix this yourself. I can give you some pointers if you feel comfortable doing this.

If you decide to call a tech, give him the make and model number, tell him what you told me and that you suspect a convergence output IC failure. He should immediately know exactly what to do, what parts to bring, and be able to fix it in your home in a little over an hour. Cost should be in the $150-$300 range, depending on where you live.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi

Thanks for using FixYa. You need to check the horizontal and vertical output wave form at the high side of the deflection which should be a normal horizontal/vertical pulse respectively. Now check the HV output transistor on all three elements and also check the regulator transistor which might have short. Replace the parts/diodes which are gone bad and can be easily replaced. You can order these from the following link --

Projection TV spares parts


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Power/Standby light blinks green then screen goes blank (off) for


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.
