Hi garnie868,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the dried-up/leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit and blinking error appear. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Secondary reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Sony Projection Televisions - HOW TO FIX TV Red Blinking light of times between 3-second intervals and turn off


I have a Sony Bravia. Smart Television that would not turn on once in standby mode. The Red light would blink twice. I unplugged the television and reconnected it using a surge protector power supply strip. This solved my issue. From now on I'll be sure to turn the television off instead of allowing it to turn itself off.

I have a philips remote control and I need the code to control a pioneer DVD player


Though all remotes are differnet just try this it can be kind of standard. But not all remotes are always compatible

1. On the remote control, press DVD once and Turn DVD player off
2. Press and hold SET until the red light blinks twice, then release SET.
3. Aim the remote control at the TV and press SCAN. The red light will blink twice.
4. Continue aiming the remote control and click on and off at the DVD Player (which may take up to 5 minutes) until it turns off. Immediately press any key except VOL-, SCAN, or SET. If SCAN is pressed again after any key stops Auto Scan, the remote will continue Auto Scan of the next ID from where it stopped. If you have passed by the code that turns off the TV, press VOL- one or more times until the TV turns on again.
5. To lock in the code and exit Auto Scan, press and release SET the red light will blink twice.


1. Or if you have a code. Press Set
2. Wait for blinks
3. Put in code.
4. Test it and if it works click set if not try next one.

When our garage door opens, my light turns off immediately. How do I get it to stay on for about 5 minutes?


Try this:

Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

Hi Sikandar,
Let me know how many times red led blinks as there would be an interval of 3 seconds so count blinks from pause to pause.
Is it Sony AR25M61 model or any other?
