Question about JVC AV-27230 27" TV

2 Answers

JVC AV-K21TR Hi, I have the same problem -- at first it seemed like it was going to turn on, but then it stopped and the "timer" light is flashing again. The tv is 10 years old, and for the past 2 months it's had faint horizontal white lines across the top inch. Not sure if that's related. Thx, pAUL

The faint white lines at the top of the screen is the warning that the pump-up capacitor in the vertical output circuit is going bad and the output itself is about to short out. When the TV stops working, the vertical output IC has finally shorted out. Replacing the vertical output IC, the pump-up capacitor and possibly a small value resistor next to the flyback (B+ for the v-out) should bring the set back to life.

Have you check the vertical output?. maybe the IC in that area.
I know this is sound funny but I already fix one of this. when it only has a vertical lines, i'm looking at the horizontal, when its horizontal I look at the vertical out.
and also check for any busted capacitors. also check your crt socket.
hope helped you..^^

Flashing of timer is fault indications. Check this site for more details. It has more than 1400 posts to different brands of electronic entertainment and other equipments. All posts referrers with the repair and fault finding to electronic entertainment equipments. It will be best to view it either in Flipcard or Timeslide option, can be selected by the sidebar tag at the top left of the display screen. Timeslide view will be the best to select.

Jvc tv av-32d502 timer light is flashing will not turn on

Hello, I am a tv tech. I worked on a JVC AV-32D502 today. Problem: led flashes / no power or picture at all. Same as trobertson52's set. The microprocessor is bad in my machine. trobertson52, if your sets' relay does not click when the power button is depressed you most likely have the same problem or the standby power circuit is at fault. That circuit supplies +5 volts to the micro.

Edtal you have a different problem with your machine. Your machine is going into shutdown. A number of circuits could cause this and would need to be looked at by a technician to determine exactly which circuit is at fault. High voltage transformer (HOT) \ Vertical Circuit \ Power supply are the most likely causes.

The set is shutting down because a problem has been detected. Replacing the remote will not help. Count the flashes and call a JVC servicer to get an idea about what the specific problem may be.
