It is pretty much a plug and play. It is more time consuming than any degree of difficulty.
You must make a strong mental note of where each screw goes.
Simply disconnect the Molex connectors and the screws on the Signal Board; you're pretty much reverse the process. No cutting or soldering is required!

I have a Phillips 42in plasma 42PF7321D/37 when you turn tv on green light lights up you have sound and picture flickers a few times and then picture is fine and looks great. Noticed menus are hard to see...


I would certainly say the problem is in your power supply. Chances are real good that two capacitors are bad! You will have to remove the back cover...this is tedious and requires patience. You will be concerned with the board on the left side. You will have to remove the screws on the power board to lift it and see the top of this board. You should see at least one bulged capacitor. Replace, and you can bet the other next to it is bad. And another note..there may be a small cap at about 16volts at 10Mf that needs attention. These are clues and should help with repairs! Thanks for asking.

No power to my Phillips 42 inch Plasma 42pf7321d/37, just a red blinking light


Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.

I need help tv plasma phillips


There is a firmware that can be updated via usb from philips. This fw was used to correct the tv powering on with no picture randomly (they called it a maintence session) but it was a problem. The tv would power on on its own and do this..


If that doesnt take care of your problem then the problem is with the main control board. or ssb

Hello gruponapa,

This problem is linked to a power supply issue. The SSB is part of the power supply chain and will cause system failure if the board is defective. I have seen to many of these type of modular power supply boards fail. The shutdown circuit is detecting excessive voltage, and in the process of turning off the set it may have blown something else. I am begining to suspect a design flaw, which happens from time to time. I would suggest having a qualified TV repair person take a look at the TV and work on it.

I hope this helps,

Thank you,

Philips 42PF7320A blinks 3 times every time i hit the power button


The SSB is small self contained board that u connect your Antenna, and HDMI to. An error three is a communication error between the SSB and to Logic board ( located underneath the SSB on the back fo the plasma panel that is just below the power supply. U can check parts.com and see if u want to purchase a SSB for this TV. Is the 3blinking lights coming from the front of the TV. Also check the power supply and see how many times the green led blinks on the upper left of the power supply and let me know.

Philips 42PF7320A/37 won't power up Led blinks 7 times


This what to do measure from the logic board which is located under the small signal board and have the AV jacks connected to it. If the voltage is 3.1 or close the problem is with the power supply or a boar connected to the power supply. Unplug the set. Disconnect the Y main board first that will be on the left side of the set facing the back. Plug the set back in if the led is solid replace the Y main and the Y upper lower. If still blinking plug the Y main back in and unplug the X main which is on the right side facing the back. If the led is green replace the X main. If the led is still blinking replace the power supply.
But if the volts are 0 the problem is the SSB or the logic board. In that case take the (SSB) small signal board out the set and place 1 jumper on J8003 and another jumper J8004 of the left side of the power supply. Then place 1 jumper on CN2072 of the lower left part of the logic board. Plug the set back in if the set displays a white, blue ect screen replace the SSB. If not and on the logic board you don't have 1 solid blue led and 1 blinking led data is not flowing and change the logic board.
