SOURCE: i have a sansui tv set with a power problem .

Hello

W11NB80 is an N-channel 800V-0.65ohm - 11A - rated Metal Oxide Semiconductor Field Effect Transistor [MOSFET]. You can use the folowing substitutions for it
[ 11NM-80, 12NK-80 & 10NC-802]. All of these are its equalent substitutions.
Before replacing the mosfet, check the entire power supply secion for any short circuit, or zener diodes faults. If any of the zener diodes are fused, it will run out the MOSET you sumstitue again. Check it keenly. Unsolder one end of each component, lifit it up a liile from the circuit board and check. Especially zener diodes must not show any leak in 100Kohms range. It is best to replace them all I suggests.
I don't know about its availability in Keniya, yet you try to get it from any electronic spare part shops. f feels any difficulty in getting the same contact [E-Bay] site, they will reach you the exact component at your doorstep. Ok.

SOURCE: ABOUT PHILIPS TELEVISION

The 8V at pin 36 won't show unless there is oscillation, the primary voltage pin is pin 10, 8v. Don't mind me asking, you have checked the B+, right? Because the blinking LED is often because of power supply problems. And if that's okay, desolder the horizontal driver output legs and connect an LED to find if it is oscillating, if it does, forget the ic part and move on with the FBT and things. Good luck.

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Lcd monitor hp model l1506 is not giving out put 5v/12 v . voltage at primary of xformer is ok .mosfet k2645 is ok.no switching is taking place.is ic sc6841s is defective

This monitor is made by AOC, you can downlod the service manual here: http://elektrotanya.com/?q=showresult&megnev=hp&megnev2=%20L1506%20&kategoria=&kat2=all
It can be in the protection shut down mode because it may be sensing too much load like short circuits. I test power supply by connecting a 12v 500ma lamp to the 12v output to see if the lamp will be flashing. Another test you can try is to use the hair dryer, heat up the small electrolytic cap by the opto isolator (a component with 4 pins) to see if the lamp will stay on solid.
