Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

often that *needs* to be done in a service center as there are some adjustments to be made after replacement; don't know about this particular TV model.

Hope this helpout........

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi

It seems like the digital board or zsus board is at fult.

The red light will flash a code. If it's 3 there are bad caps on the power supply. 2 big ones bulged near the edge. If the light flashes 7 times it needs a Y-Drive and can be a costly repair. Both are common, and remember if there's any doubt take it to a pro. Goodluck.

Could be power supply but most likely sustain boards, which are very expensive to repair. Consider replacing with an LCD with warranty!

Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. You’ll need to check the power supply board first for any swollen/bulged capacitors. As power supply board is the hardest working board in a plasma TV, it develops voltage to supply all components, high current + high voltage. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment for further assistance.

Hi,

Kindly tell me few more details :-

1. The position of the strip remains the same or not?
2. In the last few weeks,is there any change in dimension of the strip?
3. When you bring TV menu option, the strip is above or below that?

Thanks!!

Above is your user manual, below that is a pay for link for your service manual. https://www.completeservicemanuals.com/philips/magnavox/plasma-television/cat_89.html Below is a link for a FREE services manual http://www.scribd.com/doc/21281939/PHILIPS-BJ2-4UPA-BJ2-5UPA Below, is a thread, discussing this tv and some issues, perhaps this will be of assistance. I have included these manuals so you can get to grips with it all, anbd if you intend to try to repair yourself, not really recommended, then at least you have the most important tool, the service and repair manual. You see, with just this symptom, it is nearly impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what, exactly what is wrong, sometimes it may indicate the "Area", just say in your case, it indicates the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. We MUST find the damage, and repair, and, also the cause of the damage, usually never one in the same. 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 ion your case, please contact a local or head office, and ask for a referral to an Authorised Service Center. Now, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, they will have trained staff, trained on their (Your) brand, also they have first hand access to parts, original parts, too. . 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.

As per symptoms that said in question, new tv would be better as this plasma has already served you since 5 years and repair cost could be more then its worth.
Thanks.

Replaced these defective gases lekage capacitors.U tv power will function normal again.Or tries Websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hi.

The TV can be used in Asian countries, just ensure that TV PAL or NTSC setting is matching the standard in the country of usage.

Here the replacement remote:

Sounds like you need a lower Y-DRV/BUFFER board (996500032640) and a Y-SUS board (996500032643). Part numbers listed are for models which use a Samsung Panel.

are they all the time or just when watching broadcast or a dvd. are the horizontal or vertical?
