Those 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://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty.

Want to do the repair on the PS? Then get out your unsoldering tool and unsolder all the suspected parts, caps, diodes, resistors, relays, etc., making notes of where they came from and noting polarities. Then whip out your test gear and start working. Replace any and all defective parts as you come to them. If you have any IC's on the board you are sh-- out of luck - you replace if you are successful at getting the old one out. Still wanna repair? Good luck to you.
Psst - you send it out for repair and the dude is gonna replace the board - trust me.

I unpluged mine and the light was still blinking when it was unpluged. I thought that was weird. So I pluged it back in and just heald the power button in untill the light went out. It went out within ten seconds. I pushed the power button again and the tv went on. WOOHOO!!! Just needed reset, I guess.

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 anly 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, 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.

Panasonic has most of their product manuals on the product support page. For the TH-42PZ85U, see http://shop.panasonic.com/shop/model/TH-42PZ85U?t=manuals&support#tabs . Look for the Owner's Manual tab.

The direct link to the manual is http://service.us.panasonic.com/OPERMANPDF/TH42PZ85U.PDF .

I hope this helps.

It can be reset by turning the tv on and while pressing the "volume down button on the main unit, press the menu button on the remote control for more than 3 seconds. The self-check menu appears on the screen. Then, disconnect the ac cord from the wall outlet. You will back to when you first bought the set.

I purchased one from panasonic directly. TV did power up but did return to 7 blinking lights. Must be a buffer board short that caused the SC board to fail. . Not spending another $200.

No, this TV can not communicate through Bluetooth communication. However, the TV's PROG OUT audio ports could be connected to a device that works with Bluetooth.
