How to insert china power supply in tv pcb - Philips TV Tuner Video Capture PCI Card - Phillips Digital (652101138177)

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

A common problem with samsung flat panel tv's is that the capacitors on the power supply fail.
You will need to remove the back and check the power supply pcb for puffed caps. To do this you will need to lay the tv face down on a cushioned surface and remove all the screws that secure the back of the tv. You will need a surface large enough to support the whole tv. This is to protect the panel. DO NOT place tv on surface where the front of the tv is not supported by the frame.

Remove the back of the tv and check for puffed caps on the power supply pcb. This is the board that the power cord is attached to.

If there are any puffed caps, you will need to replace them with equal or slightly higher valued caps.The value ratings are printed on the capacitors in mfd and voltage.

You will need a soldering iron to remove and replace them.

After reinstalling the power supply and before you put the back on, hook up a power cord to the tv and try turning it on. If you see a backlight come on, the tv is working. Try hitting the meny button and see if you have an on screen display. If you do put the back cover back on.

If tv doesn't power up, then the power supply pcb is probably bad. Try checking the voltage outputs from the connectors on the side of the pcb. Use a digital multimeter, connecting black lead to chassis ground and read lead to check voltage on the pins of the connectors. There should be voltage levels printed next to the connector on the pcb. Let me know if this helps you.

Tv manual PCB control buttons all work?Like power on/off,volume - + and chanels + - all work than it not the manual PCB board control IR is parts of this board.Not the IR problems,when tv is finally on the remote work fully everything buttons?No,could be remote control have problems.Tv might have DM power supply board problems.

You are correct. The power supply (trace) is a very high voltage device. If it goes out, you will receive no power anywhere in the unit. It will most likely be cheaper just to replace the monitor.

Good Day;
Try these first. This TV is an oldie 1988?

POWER SUPPLY STARTS BUT WONT RUN. CHECK FOR SHORTED D909 OFF T905 PIN 17 AND/OR SHORTED IC401. (PCB-MAIN) D909 PT.# 264P521020 IC401 PT.# 272P174010 *** ( TO PREVENT REPEAT FAILURE , REMOVE T905 FROM PCB AND RE-SOLDER LEGS OF TRANSFORMER AND THEN REINSTALL) 2. POWER SUPPLY WONT RUN. CHECK FOR OPEN FOIL AT PIN 2 OF T905. (PCB-MAIN) 3. POWER SUPPLY WONT RUN. CHECK FOR OPEN R903 (220KOHM) AT PIN 3 OF IC901. (PCB-MAIN). ALSO CHECK THE VERTICAL OUT IC, LOOK IN POWER SUPPLY CIRCUIT FOR LEAKY CAPS. YOU CAN TELL BY BLACKNESS ON THE BOARDS ON THE NEGATIVE SIDE OF THE CAPS.

Good Luck, big IRISH.

sure...you can find them online..most of them are coming from China now...just enter that phrase into google.

The power supply needs to be changed. Not sure how you could do that since this item is from china and I could not find parts for this unit.
