I NEED POWER SUPPLY BOARD FOR DRC8030N

PLEASE CHANGE THE INVERTER BOARD BECAUSE YOUR 24 VOLTS ARE SHOTED

Hello Jon,

Before you start ordering and swapping parts check with Samsung, that model is covered under the terms of the class action lawsuit settlement over bad power supply boards. The power supply boards cause the exact symptoms that you are having. They should repair the unit free of charge for parts and labor. Here is additional information on the settlement along with contact information.

It sounds like your power supply has failed. This could be caused by bad capacitors in the power supply itself, or it could be caused by some other circuit board, likely the Y-sustain or Z-sustain board, or both.

This solution assumes you feel comfortable working on the tv yourself - if not, it will need to be fixed by a service technician.

Begin by removing the back cover. You'll need to take out all the screws that have an arrow pointing at them. You'll only need to remove the large cover, not the smaller one where the audio/video connections are located. Put the screws in a plastic sandwich bag so they don't get lost.

The power supply board is in the center top area. Check the tops of all the capacitors. They should all be flat. If any of them are bowed out or deformed then you have a bad power supply board that will need to be replaced, or replace the caps if you're capable. If the caps look ok then check the fuse at the bottom right of the power supply board. Go to the appropriate paragraph below.

1) IF THE FUSE IS GOOD: you likely have a problem with one of the sustain boards. Unplug the connectors on the Y Sustain (Ysus) that sit between the two fuses. Plug in the tv and see if the power supply board comes up. If it does you'll hear a click and see the green light on the front begin flashing. This indicates one or both of the sustain boards has failed.

To determine which board has failed, reconnect the Ysus connector from the power supply and disconnect the connector at the top left of the Zsus board. Try turning on the tv. If the power supply comes up then you have a problem with the Zsus board. If it doesn't come up you have a problem with the Ysus board and/or the Zsus board. The power for the Zsus board is routed through the Ysus board, so if the Ysus board is bad you won't be able to check the Zsus board.

Many blogs recommend replacing both if one is bad because they're both high failure items, and replacing one without the other means you may have to go back and replace the other after a short while.

2) IF THE FUSE IS BAD: You may have a problem with the power supply board. Check the caps for any deformed tops. If so, you'll have to replace the board or the caps, depending on your skill level. After making the replacement, disconnect the power to the Ysus and verify you have a good power supply board.

You probably have a bad T-con board. It is located (looking from the back) top center. First try to uplug it and plug it back up (reseat the plugs). I would take the T-con board out of your working tv to see for sure.

I'd verify all the cable connections first.

You could be dealing with two different problems, bad monitor, or a bad videocard/pc.

I'd swap the monitor out to verify that the computer is working as it should first. Once you determine that the PC is in fact fine, my suggestion would be to change the resolution on the PC to a lower setting then normal. Once that is done Plug the Samsung SyncMaster 215tw back into the pc and see if it powers on.

If it does not, i'd check the cables and swap them with something else to make sure thats not the problem. If you have another PC available, i'd test the monitor on that PC to make sure that it is not the issue.

After all that you'll come to the determination on what the problem is. Sadly, if the LCD is bad you'll have to replace it as they are extremely expensive to repair and generally not worth it.

However, i'd verify if it is under warranty or not, you never know! you might be able to get it fixed for free :D

There's a good chance you have failing electrolytic capacitors either in the power section
Any caps in that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
This may save you from having to replace the power supply boards.

Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering).

I have plenty of spare power boards so you can replace the whole board vs. components. I can have one shipped at $10 plus shipping.

This is due to one of the IDE devices inside (Hard Drive or DVD drive) not sending the requires "I am Ready" signal to the main board while the DVR does a power on self test. With the hundreds of units I have come across, 99% of the time it is due to a faulty DVD drive. These "Loader" brand DVD drives were on the cheap and when they give out, the unit does not go past the Hello. You can verify this by replacing the the DVD drive with any other DVD burner or DVD drive or even a CD drive that comes from a computer (IDE connector). The only fix for this is to replace the drive or simply connect an old CD drive inside and not use the DVD properties of the DVR, only the hard disk recording/playback.

Thank you so much for sending me those parts, and an extra thanks for the extras. Which happens to be what I needed to fix my problem. You won't believe it... I got your well-packaged parts today. I soon replaced the Motherboard, no change, still the same HELLO... I was so deceived... Then, I decided to replace the Power Supply, just in case... IT WORKED!... (thanks for sending me a free power supply)... Looking at my power supply, I can see that on the printed circuit under those 3 diodes, near the transformer, is an area that seems to have overheated. I will test it and give you the results eventually, as well as the results and solution if I can fix the DVD burner. I'll use the extra fan you so generously gave me to cool the power supply, seems like it won't hurt. Though I have to place it right, or it'll make the problem worse... Seems like anything wrong with this DVR and all it'll do is display HELLO... I've heard of a bad DVD Burner, a bad Motherboard and now a bad Power Supply that causes the HELLO... Thank you so very much GSAN, you did it... I recommend you to everyone out there for your fairness, kindness and devotion. We should call you Mr. FixYa!...

Bad capacitors...! Remove rear panel cover from tv. Most require a star screwdriver. Look for bulging caps in power supply board. (3300uf 10v ) caps need to be replaced with 3300uf 16v. Identify the bad caps.... Caps are bad when they are bulged/bulged and raised. A good Cap is flat X top not raised or buldged. I have pics of what bad caps look like on these boards. Email me if you would like to to see them. Caps cost abywhere from 1-2 dollars or you can buy them in lots of 10 or 12 on ebay for around 8 bucks. Caps need to be soldered on. Do it yourself (if confortable) or take it to a tech/pc repair shop in your local area. Do do that unplug all the wire harness from the board and unscrew the boarda nd take to your teck to solder on the new caps.

You can fix this for about 20 bucks if you have someone else solder or 40 cents if you buy the caps on ebay and replace the 2 bad ones yourself. If one is bad and the other is not replace them both.

The caps go bad because they need to be a higher voltage. 10 insn't enough..... 16 is plenty and don't go any higher than that.


Good Luck
