The main power regulator board should be checked for any loose solder terminals. Re-solder all the suspected solder terminals there. If you are not familiar with electronics, do not attempt to repair! Whether you suffer fatal electrical shock! Instead, contact the nearest service center!

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices and cause a wide range of failure problems. Here are some options for you.
1. Have it fixed by a professional $$$$$$$???????
2. Open your TV and find PSB. Checkfor faulty caps. If you find some (bulgedor leaking) bad caps replace the entire board. The entire board costs around $250 right nowbecause they are in high demand right now. They can be found at tv-part.com but supplies are limited.
3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
I have a tip/tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shutsoff on its own problem. I'mworking on uploading pictures to help guide people though the process aswell. Let me know if I can do anythingto help. Hope this helps and Good luck. Kaufman605

SOURCE: phillips 42ppfp5532d/05 turns itself off

This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Check for tips to look into the SMPS unit with some of my tips:

You either have a bad power supply, or a bad main board. If you are not experienced in electronics I would suggest that you take your set to a authorized service center.

When i turn on my tv it stays on the philips screen. never goes to tv. i tried unplugging it and leaving it unplugged for an hour, no help


You give insufficient information to provide you with a more streamlined solution, so excluse me for being too brief.

What I'd do if I were you is to try and re-flash (update) the firmware in your TV.

if that doesn't help you'll likely need a new main board.

TO update the firmware you'd need the exact model of your Philips. 42PFL5603D has two versions - /F7 and /27.

The update for the first is at
http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=42PFL5603D/F7&slg=en&scy=US&mid=Link_Software

The second is at
http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=42PFL5603D/27&slg=en&scy=US&mid=Link_Software

Those are Philips provided and supported pages, so you should be able to find your way around there.

Hope this helps. If it does, please rate it with thumbs up - we need your votes if we can't get your money :-)

Phillips Plasma 42" TV


It is most likely a power supply failure and if there had been no signs of problems in the video display, it is probably the main power supply rather than one dedicated to the plasma display itself.
You might leave it unplugged overnight to give any stored charge inside the unit a chance to bleed off, the remove the back panel.
The primary supply is normally on a separate board and is characterized by having mostly larger components, including one or more transformers with black ferrite cores. The main supply will be associated closer to the AC input while the high voltage supply which may or may not be separate is not.
If you can locate the board with some confidence, check it visually for any signs of heat such as discoloration of board or components. If it seems OK it may be a candidate for exchange or repair by Philips.
I wouldn't advise removing and sending it before you talk to Philips to see if this is a familiar problem to them.
