Philips model 42pfl3603d/f7 clicks and wont power on and no standby light. I replaced many parts with the Philips 272217100569 Power Supply / Backlight Inverter Component Repair Kit (from shopjimmy).

The repair did not fix it. it does the exact same thing when powered on. There is an immediate click from a small black box looking thing on the board (located near the fuse). when unplugged i hear a faint whining noise then another click.

SOURCE: Philips LCD 170S Backlight problem.. only turns on

It can be DC filters caps with leaking/bulging tops, or they have high ESR, bad transistors or IC or transformers in the backlight inverter circuits, bad lamps assemblies. Please read below and look at the pictures of bad caps, failed monitors, and troubleshooting guides.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: TV won't turn on. I hear a clicking noise near the power supply. I have no picture or sound

This is usually and most likely caused by the power inverter/board. There are capacitors and other components that can burn out and will cause the power not to be transfered correctly

Just replace the T-Con board and you dont need any soldering at all. JUst be careful for the flex connector.

I have a 42' LCD Philips TV, model # 42PFL3603D/F7. I turned it off and tried to turn it back on and nothing. I replaced the power cord and still does not come on. Help!!

Fault to the main power supply regulator section. 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. 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.

Philips 46PFL5706/F7 46 LCD TV. When you turn it on you have power. The Philips logo appears for a second then goes away. Screen is black after that.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

I have a 42PFL3603D/F7, and the tv doesnt turn on right away, it takes about 8 times for it to stay on. Any suggestions

Power supply is in need of repair. Pull out the power supply. You will find transformer (has blue tape). The location of this transformer is T701. Underside of this transformer, pin # EL41 is in need of a resolder.With a small screwdriver, scratch an area next and around this pin. With a hot soldering iron and solder...resolder this pin. Your TV will be fine. There are no capacitors to replace. This is one of the best power supplies built for Philips TVs. Thanks for asking, Matt of Martins TV.

Need to find out a part # for my philips 52PFL7403/f7 for the ir sensor

Join Date: Nov 2011 I have a Philips 47PFL3603D/F7 with the same problem. It was the IR sensor board causing the problem. You can search online to find the board, which almost everyone will most likely not have in stock, and cant be ordered. The part you need is this: 313926859181 IR Remote Sensor.

Models it will fit are as follows: Substitute Parts 313926859182

If you can find the board, great! A replacement board costs about $12.00. If you can't... we'll there is something you can try ; )

Either way, if you know it's the board, what's the harm in trying?

Remove the back from the TV. You can actually leave it on your stand to do this if you can spin it around to gain access to the back of it. Be sure to unplug everything first!!!

Looking at the back of the tv, the board will be located in the lower left side by the speaker. It will have 2 cables attached to it. Remove them, and take out the screw or two that holds it in place. There will be a plastic tab that keeps it in place also.

Take your fingernail and bend the tab back, and the board should come free. After that you should be holding the board in your hands. The side of the board with the connectors on it is the side you want to manipulate. There will be a tiny surface mounted capacitor beside one of the wire connection sockets. Take a utility knife and scrape it off/ you could use a soldering iron but it should come off very easy with a knife.

Plug it back in, and give it a try! If it works... great! If not, find a replacement board, and try that.

Hope it helps someone!!!! quote.gif
