Power supply problem with Phillips 46pp8621/79

Hi guys,

I am looking for a solution or circuit diagrams for my Phillips 46pp8621/79 TV.

I currently believe there isn't any HV power coming out of the power supply or there is a short on the driver board bringing the power supply down. I haven't done much testing as yet as it is hard without knowing exactly what voltages I am looking for and where.

Would anybody have the diagrams available to download??

Thanks in advance.

    Thanks for the info. I actually found the Service Manual. I have tested the Power Supply and it seems ok. Possibly the HV Module?? Are the any suggestion on how this is tested - aside from carefully?? I this a common fault??

    There is a constant clicking and like a high pitched alarm sound coming from the unit, but I can't yet identify which component.

    Thanks again in advance.

    Usually that symptom is related to the HV generator (flyback) being faulty

I have a 50 inch lcd phillips tv. I turned it on this morning and it just keeps clicking . I can't turn it off I had to unplug it.


Hi,

This Seems to be a Power Supply Boards.Phillips TV's are Popular for their Power Supply problems.

You need to Open the TV. Make sure it would be Unplugged. You need to Take all the Precautions. Locate the Power Supply Board. Remove the Connectors and Pull out the Board. Once you Pull out the Board, with the Help of Magnifying Glass, locate Cold Solder Joint. If Everything is OK, then you would Locate Bulged / Leaked / Swelled Caps. They would have Ammonia kind of Odor. You need to De-Solder them. You could take the same to Radio Shack / Fry's / Order Online. Once you get the New Caps, Solder them and it is all set.You also need to Check Fuses around that.

If the Problem Still Persists, get back to me with Make and Model we would Troubleshoot other Components.

Let me know, if needed further assistance.

Hope i helped you.

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

TV picture went out. stand by/timer light blinks when I turn on the TV. no other response from TV.


The timer light blinks representing the fault on the tv. If the tv blinks in an orderly fashion then the number of blinks before pausing is used to indicate the fault. This can only be determined by looking at the service manual for that set. If the blinking is continuous without pauses after a number of blinks, then it indicates there is a problem and the first place to look would be in the power supply. Either the power supply isnt supplying power to the Line output transformer i.e an open circuit or short circuit..OR the line output circuit has a short. Without a diagram i cannot guide you which components to check..but..swollen topped capacitors in the power supply are a give away :)

TV won't come on - get a blinking red light instead


Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you the flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

I need help tv plasma phillips


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,

Noisy Phillips 32p w9308 tv


HI Brad,
I wonder if the coil was on the cord for the power or in the tv circuit board. I would definally suggest you replace the part with the correct part as I'm certain the engineer that designed the set wouldn't have designed it with a coil if it wasn't needed. I do have lots of used parts from junk sets if I knew what yours was exactally, I would be happy to send you one for the price of the freight. Let me know if I can help.
