The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. 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.

SOURCE: Philips 47PFL7422 Flat Screen no power

Check the main fuse
If that is ok look for puffed up capacitors on the power supply
Check the 1000ufd @ 35v change them to 1000uf @ 50volts

Good luck

U have all the tools like a soldering iron,a desoldering pump or a roll of desoldering braids,a roll of solders,also can do basic soldering and understanding of basic electronic?Yes,take out the tv power supply board,by checking it carefully ends to ends looking for dying capacitors parts,it alway bulging up on it tops or puffing up on it tops are the most common failer on the tv power supply board.By replacing all those dying capacitors,u can check the Zenith power supply board for capacitors for parts to replaced.Capacitors are very important must have the same exact micro ferit ok the voltages 5 or 10 voltages higher no problems.Take out capacitors and putting in different capacitors or new capacitors to a board must make sure polarity - + putting it in correctly to the board or will causes explosion,kill that new capacitor and more damaging to that board or the unit u tries to fix.

Have a phillips 32inch lcd...turn it on and nothing happens seems like no power at all no lights no noises...tried other electronics in same outlet and it works... wondering if there is anything i can...


This is a common problem with lcd panel tv's. There is a problem with your power supply. Here are the steps you need to take.
1. Lay the tv face down on a cushioned table. Make sure the table is large enough to support the entire tv, You don't want to damage the panel.
2. Remove all the screws securing the back of the tv to the front.
3. Remove the back
4. Check the power supply pcb for puffed capacitors. If they are puffed, they need to be replaced.
5. Remove all connectors and screws from power supply pcb. This is the board where the power cord attaches.
6. Replace capacitors with equal or slightly greater valued capacitors. The values are marked on the capacitors in mfd and voltage.
7. You wil need a soldering iron to remove and replace them
8. Install the power supply pcb back into the tv and replace the connectors
9. Connect the power cord into the back of the tv and turn on.
10. Check to see if backlight comes on.
11. If it does, press menu button and lift tv up to see if you have an onscreen display. If you do the repair is complete.

If you don't you need to take a digital multimeter and check the voltage ouput from the connectors of the power supply pcb. Connect black lead of your meter to chassis ground and use the red lead and touch each individual pin to see if you have the correct voltage. The voltage levels are printed on the power supply pcb. If they are non existent, then you need to replace the power supply.
You said that you have no power light indicator led on the front panel at all. This tells me you have no standby voltage. Good luck and let me know how you make out
