Why does dooropener lights blink when butten is pressed

1. If both round and long LED's are blinking, unplug the opener motor for five seconds, and replug. If the lights go back to normal, it was just a program error. If they both continue to blink, it's probably not user-serviceable.
2. If the round LED is blinking and the long LED is off, it is usually the door sensors that are obstructed or knocked out of line.
3. If the Long LED is blinking and the round LED is off, it is usually a bad roller or hinge that won't let the door move freely, something stuck in a track or a bent track.

one of the buttens are pressed or stucks try also to open it and to clean the points of contacts.

On Sony the standby or red is for shutdown---

If you unplug the set and plug it back and turn it on and it repeats this look to see if the light is either constantly blinking or blinking a specific number of blinks---specific number would be an error code.

may be battery not contact well first clean the battery contact and try again if not work pls face the remote controller LED to mobile phone camara and press the buttens you can see blinking LED in your mobile phone LCD screen that means your remote is ok and problen in your tv if you can't see blinking light in LCD means problem in remote

Hi,it sounds like your lamp needs to be replaced this will be the part you need XL5100 found Original Philips lamp here: http://www.discount-merchant.com/SearchResults.asp?Search=XL5100+ God bless you!

my tv is FD Trinitron WEGA KV-HA21. when i press the power button it starts but after about three secounds it trips to stand-by and starts blinking four quick succession at intervals

when you press the botton the light comes on then goes off

there is an internal short that needs to be eliminated about 250,00 to fix it

The standby light should blink in a repeated count separated by a 3 second pause. If you can post the count here, we should be able to provide you with details about the problem circuit and what will be required for repair.

Thanks,
Dan
