20 Most Recent Panasonic TH-42PZ700U 42 in. Plasma Television - Page 5 Questions & Answers

I have a similar problem.  It turns on ok, but after an hour, if I turn it off and try to power up again I get 10 flashing red lights.  Must unplug and wait to cool down to room temp - then it works.

 

Had the H-PCB and DG-PCB replaced and still no luck.

 

I am exchanging for another one.  The service guys want to take it with them, but would provide a loaner.  Need to return this within the next two weeks to get an exchange...

Pamoya,

I ahve found a PDF in realtion to the "Blinking Light of Death",Panasonic has several problems. I have the same Plasma th42pz700u. the LED is blinking 7 times then repeats. The possible problem fron the PDF is this. Its in trouble mode SC floating voltage SOS. with defective boards. the boards are mostlikely one of the following depending on the flow chart. SC, SU,SD,or the P board.

Hope this helps.

Marine on a mission here! To help every one that takes the time to post their problem. Times are tuff. PPL need to put food on their tables and not worry about calling in a tv repair man and spend hundreds. Took me a year to get the fix. Fixed 2 50" plasmas for 80 cents. After being told it would be better to replace than repair. BS! I held out glad I did. This is free advise, it will cost your your time and some pocket change.

The 7 blinks means that the SC scan drive board might need to be replace but only after checking the voltages from the power supply. If the voltages from the power supply are normal, then proceed to replace the SC scan board.
Click here to find the board you need. and about the cost is near to  $170. for anything else let me know. thanks.

It looks like your <a href="http://www.digitaldirect.co.uk">TV</a> is faulty. You will need to get a qualified engineer to repair it.

hello, if you have a waranty for this tv dont wait take it back to the store for a replacement or repair. contac panasonic for details. they offer a free in home repair service but only if your the original buyer and the set is still covered. this is a not easy or a user repairable situation it is a circut shutdown cuased by a fualty power supply or bad internal board, blinking lights mean theres a shutdown circut preventing full power up panel status.11 blinks pana (th50pz77u) = pb board bad or fualty
since the pb board is a small part it may be a quick fix for a service tech and may not be as much as a power supply or other internal board.
in one of my panny service manuals this 11 times blinking indicates a bad pb board this controls the fans and feeds back to the other other circuts if it is bad it cuases the blinking fualt.
blinking times indicate what is wrong with the tv..
since i dont have your model number i cant tell you specifically if this is the problem, the pb board is one of the smallest internal boards . this info is from a service manual for (th50pz77u)
what is your model number?. the tv is blinking this means it is in need of service it is still repairable. sometimes components you pluged in the plasma may cuase fualts
also if your power outlet is not properly grounded or is not correctly wired you may get trouble. there are 12 diferent blinking sequences from 1 to 12
generally a service tech can come out and check it for you and may be able to fix on the spot. if you have a waranty your doing great if not try a service that offers free in home estimate there are many who will give you a free in home estimate and compete for your business..

hope this helps good luck

plug it back into the wall and see if it stays on

hello, you may have to get your tv serviced soon. it is developing internal board trouble. the plasma screen is controlled in sections by different boards or they work together to produce a sustainable image. it helps to have a picture to see what section has the line then you can get an idea of what board or boards are fualty.
there are many resistors capacitors and diodes and all types of components that with time get hot or over heated and loose there resistence properties or voltage values they become weaker or higher depending where the fualt is. this cuases the boards to go bad.
a local plasma service tech can give you an over the phone ruff estimate for the repairs if you can describe the trouble then you can decided to get it restored. the price depends on what board or boards are developing circut fualts. its cheaper to get it fixed now that it is still functional at least you know most of the circuts are okay..

good luck hope this helps

hello, you may need to get yourself a power line conditioner or a ups "uniteruptable power suppy" and plug your tv to ups plug the ups unit to your power source, seems your wiring is shared or distributed to the kitchen and possibly other rooms.or you may have some bad wiring or imporperly grounded distribution of the power from your main fuse box

try new inverter panel

Not totally sure what your asking but I think your saying your LED lamps aren't working, if that's the case replace them
