Sounds like a problem with the power supply or display board/main board. Time
for a service call.

How many times does it blink? That's a service code
diagnostic to what the problem might be

cireric13,

Your most likely problem is bad capacitors in the power supply. I have a tip at http://www.fixya.com/support/r7490709-plasma_or_lcd_turns_momentarily_shuts which explains how to check the unit and where to get the replacement parts.

Thanks for using FixYa and for the great rating and testimonial.

Hi.

I am sorry, but I will anticipate that I won't give you any good news here.

A thin black, red or green line in plasma TVs means that a column in the plasma panel is getting incorrect voltage. When the problem is stationary, and when the line appears regardlessly of the source used (receiver, dvd etc.), then you have a bad plasma panel. Ususally the ICs integrated in plasma panel connectors start failing, or there is structural damage to panel.
Because of the cost of the panel, the TV is usually considered beyond repair. The problem will generally get worsening in time until you cannot use the TV anymore

Hi,

Let me provide you complete details as i am aware of this 7 blinks error.

Either the power supply has an issue , or you have a bad buffer board and Ysus scan board or both. 4, 5 or 7 blinks may mean power supply , 6 blinks usually the buffers and y board.
A repairman will usually just order the boards and you will spend over $700 probably around $850
It could be just a few bad capacitors on the Power Supply.
The Y board if its bad it should be replaced with the buffers together
If you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on top.
The ones you are looking for are located almost center bottom of the power board,Usually I can see them clearly with the back on simply shining a light into the back through the holes.
look at the photo I am uploading to see what a bulging cap looks like



With the back removed you will see a few circuit boards the large one the AC cord runs to is the power supply, it has alot of capacitors on it (cylindrical standing straight up soldered in and marked on the sides with the positive/negative sides and uf and Volts values)
Philips uses 2200uf or 3300uf at 35Volts rating capacitors, they cost about $1-$2 each . Read the side of your caps for the correct value
usually I replace two of them (or all the bulged on top ones) .
To buy capacitors click here
The power board and back unscrew with a torx bit and screwdriver size 10 and 15 , if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.
We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.
You can replace the whole power supply, but Philips has a few versions in their sets and some so called replacements won't fit due to cable location (sockets) being in a different spot.
If there is a blinking red light on the TV count the blinks,if it still blinks after replacing the swollen cap this would indicate another issue.
I hope thats all it is (usually is), if there are no bad caps post again so I can tell you buffer troubleshooting steps and locations.
here is Philips Phone 1-888-744-5477 in case you need it for exact part numbers or check encompass.com login as a guest and run a search by model number.





Above is the picture of power supply board. Not to mention that kindly take all the precautions before attempting to repair this TV.

These caps could be easily available from radioshack or fry's.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

When this type of damage has occurred, many problems will arise. For example if the screen is cracked...the replacement may exceed the cost of a new TV. There are lots of possibilities that other internal damage has been done. Best idea is, to shop for another TV! Sorry..this is the best advice. Thanks for asking and show a few hands of support!

6-7 blinks means there is an issue with the power supply...
I found a replacement for my 42pf9631d/37
Part # Lj44-00117A
at TSM Inc. for $110.95 with free shipping...

Hi,

Either the power supply or high voltage transformer is shot. You have either one or the other in your set. Most likely faulty high voltage transformer which commonly burn out quick nowadays. You can test it with a voltmeter .Also check for bad capacitors.

Please get back to us if you have any further query or else accept the solution.

Thanks for contacting fixya.com

This happens when the TV goes into standby mode. The slow startup is caused by the pre-set delay that allows the light tubes and inverter to warm up. As your set gets older this startup may take longer. Plasma sets, unlike standard HD TV's use more power to produce a better video experience, and as such place more demand on the power board. Your power board may be wearing down due to age, or if it is a newer set, may have a faulty HV capacitor.

That is caused by capacitor bleed of the larger of the High Voltage capacitor as it arcs to ground. The clicking you hear is this arc grounding. To verify this reduce your room lighting and look through the vent holes on your TV set. You should see intermittent flashes of light. If this is the case you can follow my guide which shows you how to identify, and replace your powerboard.

You will need to check the remote for IR emission with a tester Only if confirmed can it be confirmed if the IC is working , is out of frequency or the crystal is faulty.
So solder all the above items in the remote and check,
If working the fault can also be in the detection inthe TV.

It is possible that you may need to download an upgrade to a flash drive and then with the tv off, insert the flash drive into the usb port on the tv. Turn the tv on and it will load itself. Check Philips website for updates...

You need to copy the autorun.upg file from the sub folder to the root directory of the zip drive. I had the same problem and it worked after I did this.

Possible that the set has tripped on an error protection. there is a fault in the main board, possible in the HT section, power drive section. Might need to check for a power driver short, a capacitor failure or a display driver .
Releasing the power to the section will identify the line of trouble.

That can be the value of the cap, 0.5uF (Micro Farad). Is that what is printed on the body of the cap?
