Question about Sony FD Trinitron WEGA KV-27FS100 27" TV

Make sure your tv is un-pluged at the outlet,there,s something wrong with your video section.the tv is going in self-diagnosis function.with a ohm meter ,locate the C board, then check Q705,Q732,Q761 in the video out section. then check Q218,Q219,Q220 this would be on the A board,turn up the screen a little, this could be IK blanking..be sure to check all solder jounts,for cold jounts,bad even some with very little solder on them,i have many times found this lack of solder to be a big problem.........hope this helps..........

I would certainly go in there and check out the audio amp IC. Been a while since I repaired one of these.....The audio amp in this case may have a built in timer inside the same IC. As we speak, I do not remember the location. Please note it is on a heat sink and think it is a TDA series. When you find this IC, it will cross with a NTE semi conductor . You will see a schematic telling you it is, an audio amp with built in timer. Thanks for asking and show a few hands of support.

in this model error 5( 5 blinks then 5 blinks) is indicating AKB, TOO LOW or ABSENT beam current. Meaning the tube has gone bad. You will need to replace the tube. I am sorry for the bad news.
hope that doesnt hurt my rating.

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 slightly.
