My Utilitech Pro will come on, after a few seconds it will blink twice and then will not come on again for several days.

Usually when a motion sensor light blinks LED or otherwise it means that the motion sensor is shot. The light itself is most likely good and for whatever reason you got a bad sensor upon purchase.

have your alternator checked,it may not be working and is not charging your battery,thats why it dies so fast and won't start again.

The tv is going into protection shutdown. It will try to power up three times, but each time it tries, the microprocessor recognizes an overvoltage, or overcurrent draw, and after three attempts it will place the unit into protection shutdown. There can be many causes of this, but the most likely one is that there is a short circuit in the high voltage circuits. You probably have a shorted flyback and associated components.

it can be the problem with sp3

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Try to re-install the drivers for the drive.
Hope this helps!

you need to find out what codes have been set
one of your coil packs is going bad.
the code should tell you which one
let us know how you do
later

My 36 wega did the same thing last week it must be contagious. Blinks 7 times mostly but sometimes 6 if hit power switch again. The problem is the D-boards shorted Flyback high voltage transformer but the ones Sony is selling $130 do not hold up and seem to burn out in a few days, yes twice bitten. Finally they send me new D-board can't wait to see if this fixes it once and for all. The board costs around $200 but is worth it to get it running again.

does the from led blink if so how mant times pause then blink again?

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!
