Power supply problem.

Yikes, that is very bad news indeed. It is the PDP of the unit (the whole display) that has gone bad. It is replaceable but a new one costs more than a replacement TV...
I'm so sorry about that, but you are in trouble here with this unit... If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.
You can get a replacement TV that is much better quality for only $650 ~ and free shipping no tax, for example this one on Amazon:

The repair of this tv will unfortunately cost more than a new one.. check into the credit card option, I have successfully received refunds from American Express for example on 4 year old tv's, $2500+...
Thanks Tim

check for bad connections leve it running and check what is heating up on the power supply look for bad capacitors try borrowing esr meter check all the capacitators

I assume that you have checked the Y and Z -sus boards and they are ok. Yes most likely the panel itself is dead, but its possible that the ribbon connectors to the panel are faulty.

the blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one


Hope this helped

Can you describe the lines better. Color, number of lines, thickness of lines, area of screen the lines are on, etc. Also, just to confirm that it is a Samsung Plasma tv?
Thank you.

Hi


Thanks for using FixYa. To start with unplug the unit and take the back off then check the Y-main and buffer boards for any bulged/swollen components. Also check the controller board which is the board located next to the power supply unit. As there is no picture so it can only be an issue with one of these boards or a component that has gone bad. All this is only recommended if you have electrical expertise and/or 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.


Thanks

replace y lower bufer board about 100 dollars

Try this step before purchasing power supply. I have serviced this tv before. Lay it flat plug it in and it should turn on,but once you sit it up straight it will turn off. I think there are faulty fairchild mosfet transistors or a firmware issue. I put a 1 inch thick book under the stand so it tilts up or down. I have not had a call from any customer since.

I REPAIRED A PLASMA OF THE SAME SERIES TO NOTICE THAT THE HDMI WAS VERY LOOSE

It sounds like either the X-Main board or the Main Board has failed. I recommend calling 1-800-samsung to find the nearest service center to repair it. You can spend a lot of money replacing parts on a plasma before you find the defective part.

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

It is going into a safety shutdown either because of a board,panel malfunction,or maybe just the power supply not coming up fast enough. If the small capacitors in the power supply are the problem....may be an easy fix....otherwise checks need to made within. if you are tech nical,I can guide you to sove yourself,other wise a repair shop may repair for $200 to $300

What you have wrong with your tv is in the power supply board, it is a very common problem which you can fix yourself for around $30 this is a MAJOR Samsung problem and thousands of people are having this problem. What you need to do is deenergize your tv and lay it face down on a table so you can work on it. Use a philips screwdriver to remove all the screws on the back cover of the tv make sure to remember where they go for when you put it back together. Remove the back cover and follow the two wired from where your tv power cord comes in and in the middle of your tv they will plug into a board, this is your power supply board. Look for blown capacitors, also check the fuses the tops will be bulging upward and caps have writing on them like 10v 1000uf or 2200 uf and 3300uf are the most common. What you will need to do is replace these with a 16v cap but be sure the uf number is the same, and you need 105 degree rated caps. There is also a negative side to the capacitor which is marked with a stripe and a shorter leg on the bottom, these have to go in the same way or you will blow the board, remove the board with screwdriver and disconnect all wires, now you will need your tools solder, soldering iron, and preferably a solder ****** to remove the old bad caps here is a youtube link that shows u step by step just go there and type samsung power supply repair, and whether you have a vizio, philips or another model that this is posted on they all have samsung power supplies in them so if you are having power problems this is your fix, you should be able to get all your parts at radio shack or on the web. Thank you and votes are welcome and if you cant find the parts get to me and I can help you get them
