Hiya Roy!

I'd recommend running a diagnostic and seeing what codes pop up. To run a diagnostic you need to enter the service menu:

Access the service mode: set SLEEP TIMER to 0 MIN.
While this is still displayed, simultaneously push DISPLAY and
VIDEO STATUS.

If you're successful in this, please report back with any codes that it turns up.

Good luck!

42C128135UA-52 Phillips Flat Screen TV. I switched it on and all i got was a clicking sound and flashing green LED light which continues 1 long flash 2 short flashes. No picture whatsoever.


On the lower right side of the psu, (clamped to a heatsink), i changed the 8.5v (L4940P85) voltage regulator and it worked. As a test to single out the fault i warmed this component with a fine blue flame, this would make also make the tv work perfectly.

Kyocera fS-920KX. Not printing


There are actually some certain meaning on the red light and green light showing different information to user. The summaries are:
1) Green On, Red Off = Printer Ready.
2) Green Fast-Flashing, Red Fast-Flashing = Printer warm up.
3) Green Fast-Flashing, Red Off = Printer off-line.
4) Green Slow-Flashing, Red Off = Processing Data.
5) Green Off, Red On = Cover Opened, Toner Empty or Developer Unit / Drum unit missing.
6) Green Off, Red Fast-Flashing = Paper Jam or waiting for jam reset.
7) Green Off, Red Slow-Flashing = Paper Empty or Paper tray is not inserted.
8) Green Off, Red Off = Printer power is off.
9) Green Very-Slow-Flashing, Red Off = Printer in sleep mode.
10) Green (any condition above), Red Slow-Flashing = Toner low or paper empty.

So what is your printer condition? Better know what is going on your printer so can solve the problem

Stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.


thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!
