Question about Televison & Video
The problem with this unit seems to be that the voltage over the main fuse is pulsating as the green led on front of unit is flashing in the same way.It got me thinking that maybe the oscillator is not kicking the unit out of standby,but with no curcuit diagram and having great trouble in obtaining one,not that i have'nt tryed,your help would be most appreciated.Many thanks Mr.S.Hatcher.
Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hi kamil. Mo medenom, nomogom! I think problem isn't in power supply. It should be in control board (madaar-e farmaan). Hossain Shahidzadeh

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

Modern Ducatis (and cars) don't have a conventional flasher. The blink rate is controlled by the dash cpu. The blink rate change is used to indicate that a bulb is out (by sensing low resistance). Using a resistor will fool the cpu into blinking correctly.
