The TV may have become over-volted from the factory and the voltage settings have to be reduced for the dots to go away.
If you have speakers by the TV it will do the same thing.
You may also have what we call "burn-in" they are ghost-images that appear as bars on your screen
Try Adjust the CONTRAST setting at or below 50%
Most home theater professionals advise that you wash out your screen with your television's anti-burn in calibration after the first 100 hours.You will have to check your owners manual.

My first solution is: Make sure you leave TV unplugged for 4 hours or overnight. You may have to do a couple of resets.

If you get a wide vertical strip it is very rare; it means the horizontal deflection system is weak - but strong enough to produce the high voltage.

I think the full, hard reset will solve your problem. In the worst case, you may have to go into the service mode and readjust some of the settings.

    A hard reset is when youunblug thetv for at least 4 hrs. The processor inside resets itself.
    I unfortunately have yet to find a free manual online. I will spend alot more time today searching for one and will let you know if I find one.

    If you would like to purchase one, you can either go to the philips website
    or
    You can go tohttp://www.servicemanuals.net

    I believe If you hit your menu button twice
    or go to menu and there should be a picture menu that has:
    brightness
    color
    contrast
    sharpness

l think you mean no picture except for the display for color and sound--If menu comes up also that means the OSD is ok.


Video problem in that case and almost certain the main board is the reason.

LCD Turns Off after colors go crazy (inverted colors)


If the 5V are 3.3V then either
1) You are not measuring it right
or
2) The problem is at the power board, not the SSB; swollen caps on the power should be seen with ***** eye if that's the case
or
3) The problem is on the SSB board where the 5V are used for bunch of things, including step-down conversion to 3.3V used by bunch of the main processing ICs and likely a step-up conversion needed by the video decoder. Any one of those could be overloading and causing the drop.

But everyone with pro skills with a 2 channel scope should already know all that, wouldn't they?

My panasonic plasma has spots of bright colors where they shouldn't be.


If its four years old that is about the average lifespan of one of these sets; a guess would be either voltages drifting or off in power supply or one of the signal boards that processes information is going bad.

Philips 42PF5321D/37 Error Codes


replacing ssb for 4 blink error was correct as error is communication failure specific to micro processor on ssb. getting an alternate error after replacing ssb would suggest either wrong ssb or defective ssb. verify vendor number on ssb tuner on original and new ssb and if same reorder that board and if not order per original board

Measure the connector from the logic board to the power supply the second pin from the left it will say Vs_ On if the set has 3.1 volts the problem is the SSB or the logic board. On the logic board there should be a solid led and a flashing led that shown that data id flowing and the problem is the SSB. The SSB is easy to replace just remember what you tokk loose and from where. You probely will save money that way. If the set is in warranty or just out of warranty contact Philips 1-888-744-5477 and see what they can do first.

The set has sound and no picture.If you the SSB could be the issue but the tiny red dots on a black screen will need the panle replaced also. There is a way troble shooting can be done to determine if you will need the SSB or the SSB and the panel.

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.
