Question about Sony Televison & Video

Red flashing light

My TV is a Sony Wega KV-BZ14P40. Recently it started turning on with the usual green flashing and it settles but very shortly thereafter it starts to flash in red colour. It flashes red 5 times in a row, pauses for about 3 seconds and flashes 5 times again over and over. The picture is also dull especially when I just turn the TV on. Can you help please?

  1. 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.

Most likely the flyback assembly, and or the horizontal output transistor failed. There is also a possiblity of some other faults that are putting the power supply in to the protect mode.

If there is a scan failure, it is possible that there is also some damage in the power supply.

The set will have to be serviced by a TV service tech.

SOURCE: Missing Green colour on 36" Sony FD Trinitron WEGA

This is not a problem that a reset will fix. THe 5 blinks is a code that indicates a problem with the AKB circuit. There is a possibility that the picture tube is starting to fail, but that is rare. If you are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, let me know and I will provide additional details and instructions for a couple of repair options.

regards,steve.
ps.line output transformer failure rates are quite high on these sets,usually resulting in two red blinks-pause-two red blinks-pause etc...

Will not come on and front lights flashing red +


If your set is the KV-24FS120, then the standby light should blink with a repeated pattern. Count the blinks and post that number here. It is a diagnostic code that will indicate the defective circuit. Having that information will allow us to suggest repair options.

Thanks,
Dan

I have wega KV-HR36 red light flashing 10 times


Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Sony FD Trinitron WEGA KV-24FS120 24" TV Color changes


Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
