1 Answer

Sony ballast Our Sony KF-50WE610 just had the replacement video block replaced and after about 2 weeks it wouldn't start and flashed the 5 code. I've been told it was probably the ballast. Is that something that can be relaced easily? The lamp is OK.

I am getting 5 blinking red lights before going solid red; already replaced the projection lamp approx. 1yr. ago My Sony 50" KF 50WE610 model is about 7 yrs. old. Please give me some guidance


Hi dalposadas,

5 blinks of the standby led lights is an error code for no high voltage coming from the ballast board.
You have to check first if the supply voltage from the power supply is present feeding the ballast board. If yes, you have to replaced the ballast board. High chance that the fault came from it but you need to confirm it by the presence of the voltage from the power supply.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Sony LCD Model KF-60WE610 lamp was replaced and then it shortly after stopped turning on. Blinks Green 6 times then Red 6 times Please help!


For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.

New lamp turns on flashes 7 times


Just a thought...you *might* have a bad ballast in addition to that defective power supply.That flashing could be the ballast trying to ignite the lamp. A lamp is just like an enclosed welder's arc. The ballast generates a high-voltage spark to initially start the lamp, then low voltage with high current keeps it burning. If you look into the lens and see "lightning" flashes but no lamp ignition, that's what's happening. The ballast could've been damaged by the defective supply. Also, try a known-good lamp...just to rule out a defective new one--in the shop, we kept all old working lamps as testers.

SONY GRAND WEGA KF-50WE610 can't turn on TV screen.


Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,
Dan

KF 42WE610 turns on for two seconds, then goes black


no, had the same problem. Its the lamp ballast also called the lamp power block. It supplies power to the lamp, any how some repair shop wanted $450 to fix it, so i ordered the part from sony, part #146879816 ($116.25), trust me this is the part I double checked with many different places. Any how fixed it my self took about 15 minutes, just take the back cover off and the part is right there just kind of follow the screws and the 3 wires, super easy job, I suggest you replace the bulb at the same time, dont by a cheap bulb just get it from sony
