You need to work through the troubleshooting procedures in the manuals and try and isolate your issue. Remember, you will usually have multi-headed problem, ie: The bad bit, and what made it go bad... you must fix the cause and repair an damage. use these manuals and they will help. With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of only a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, Philips, in your case. Now, I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

Hi


Thanks for using FixYa. To check what has gone bad you’ll have to open the back of the unit and check the backlight inverter board. The inverter is the power supply source for the backlights. If that’s the issue then it’s always better to replace the inverter board completely just to avoid any future issues. If not then check the power supply board however, it seems to be the inverter board as the sound is still working fine. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

    Hi,

    by backlight are you refering to the side 'ambilights'?



    I have opened the rear cover and the layout is,

    the tuner/processor/AV board in the middle,

    the large brown P/S board to the left,

    above the tuner board is a board which is metal shield encased with 3 ribbon cables to the left labeled

    display, display and SSB,

    also the cabling to the ambilights come from this board.



    Then on each outerside there is i think the inverter boards.



    Have inspected all 5 boards and there is no apparent visual damage to components or pcb.



    As before there is no picture or ambilight working so the screen is black,

    but there is what i am calling the lcd 'backlighting' working.

    Cheers.

    As you have already checked the boards inspect the power supply to the inverter board, this can also happen if it is not getting power. Please do accept the solution if the issue is resolved or post a comment for further assistance.

    Hi,



    Have checked the power supply board and is ok,

    and at both Master & Slave inverters I have 24Vdc and these two boards are operating the HV backlighting to the screen.

    Still no picture!

    What does the blue flashing code i mentioned mean?



    Jim.

42 Philips tv won't turn on just blue light flashing


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

Philips tv lcd model 30pf9946/79 troubleshooting guide


Show a flashlight on the screen from a safe distance and check whether you can see the picture. If you can, the backlight is not working. Then I suggest it is better to refer it to a qualified service
technician, since the back cover has to be opened for investigation/rectification.

Screen is black but we have sound


The problem is a faulty inverter kit (2 boards).
I live in the Netherlands and had it twice, tv is 2 and a half years old! In the Netherlands Philips replaces the inverterkit without any
costs for the consumer (even after warranty time) cause they have
admitted that it is a production fault.Philips made a new inverterkit
which should solve the problem indefenit.Be sure the kit is Version
1.3! I had 1.2 after the first problem, and that went wrong after 7 months again. Today got revision1.3 installed which is Philips final solution.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
