    I don't know a lot about circuit boards as far as repairing them but I have changed entire boards out before. Would you by chance have the part # to the inverter board or know where I can find it so I could get a price on one. Thanks for your help

Hi


Thanks for using FixYa. Five blinks means 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. There might be a backlight and/or an inverter board issue. It could also be due to the inverter circuits for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

KDF-E60A20 Going on and off by itself..no blinking lights


it works!! First i took off the front panel. Just check your manual for instructions, very easy to do. If you do not have a manual just down load one from google.. The instruction are easy to follow. The screw they have you loosen with a alan wrench is attached to the plastic, so you do not have to worry about dropping it inside the tv. Removing the lamp was simple. once out you will notice on either side are two small mesh screens. One of mine was 80% blocked with dust, the other side was only 30-40% covered. I used a vacuum to remove the blockage, i did not want the dust and dirt to go inside the bulb. i then cleaned all around the lamp. Reinstalled, and we are go to go. The kids are happy and i am happier since my wife not be buying a new TV.
total cost of repair $.00
time required to fix, less than 15 minutes.

Also when my TV was loosing sound and picture and then return. I did turn off my TV, then turned on. I nothiced a red blinking light. Mine flashed 5 times. After some reserch, 5 times is video related, bulb or video board. google red flashing light with the model you have and you will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.

hope this helps.
