The light flashing 5 times is normal at turn on as the set is monitoring current drain on the pictures tube cathodes. Any speakers near the set that have un-shielded magnets could possibly cause color issues.

I have a sony wega trinitron, when the tv is turned on, (no visual, or sound) the red stand by light blinks 7 times, and you hear the tv click off? Please help

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

The tv is at least 17 years old.The blinking red light blinks 5 times ,then the tv picture goes off . The voice is still on

Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.

To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.

There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to set the tube up (a process called convergence), so you'd need to find someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.

My 35 inch tv had a major failure today. while

If red LED light in your TV flashes in series of 6 or 7 blinks TV is repairable - High Voltage IC need to be replaced. If anything else, beside fuse in Power Supply - than forget about it.

My 32'' sony wega blinks 5 times

The 5 blinks means a problem in the set's AKB (auto kine-bias) circuit. Sony TV's monitor the operation of the picture tube. When some kind of trouble has been detected, the TV blanks the screen and flashes the 5 blink error code. This may be due to problems in the video circuit, a bad picture tube, or adjustments that have changed due to aging of parts. There isn't anything I can suggest you try on your own to fix it. Because several things may cause the problem, and the proper tools and service information needed to troubleshoot, you should refer this repair to a professional.

SONY WEGA KV-36HS420 will not come on

The blinking is an indication that the set detected a problem. The code usually indicates a bad regulator circuit. If yu can solder, you can probably fix this your self. Please let me know if you wish to attempt the repair. If not, expect a parts cost in the $25-$40 range plus the local labor rate for the repair.

36 inch wega trinitron

If a red light flashes for more than a few minutes,disconnect and reconnect the power cord.
Check the TV/VIDEO settings
make sure you have inserted the batteries correctly to remote control.
Try another channel to rule out of station trouble.
if the problem continues may be a power supply problem.
good luck ! please dont forget to vote if this suggestion is helpfull.

36 inch sony wega trinitron

I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.
