Samsung 213T Repair – No Power/Picture

Filed under: Monitor Repair, Samsung 

Today we have a non-functioning Samsung 213T LCD monitor, this one has no power. This article will guide you thru the repair of this unit. The power supply board is the BN41-00296B also known as NB24BS/NB21BS.To do the repair you will need the following tools: Soldering iron, de-solder braid, Phillips screwdriver, flat blade screwdriver. You will also need the following electronic parts: qty(6) 1000uf 25v capacitors and qty(4) 220uf 25v capacitors. We sell a repair kit with all of the parts for $14.00 This is not guaranteed to solve all problems but in most cases this is the issue with this model.

If you don’t want to do the repair yourself, then please use the service request link above.

The first thing you need to do is remove the monitor stand, power cord and signal cord.

Now use the flat blade screwdriver and insert it on the bottom of the unit between the two halves of the case and the latches should start releasing. Once they start just work your way around and set the back panel to the side.

The next thing to do is remove the metal RF shielding from the power supply and CPU boards. You will need to remove a bunch of Phillips screws as shown below circled in yellow.

Now you will see the boards that we will be working with. The power supply board is the center one and the inverter board is the one on the left hand side.

The two boards we will be working on will need to be removed from the unit. The capacitors that need to be replaced are circled in yellow on each board below. The power supply board uses the (6) 1000uf 25v caps and the inverter uses the (4) 220uf 25v caps. Remember, be sure to insert the replacement capacitors with the polarity correct. After the capacitors are replaced then reassemble the unit and you should have a working monitor again.

  2. Great site. I just replaced the top row of bulging caps on the PS board and it’s still not working. Measured power at the board output: the 14V and 5V lines are producing 13V and 5.1V respectively. You think I should replace the other caps too or is something else wrong with the board? No visible problems on the other caps.

  4. Nevermind. I think I narrowed it down to two of the caps on the lamp board. Will replace those and lyk.

  6. Be sure to also check for shorted FETs and blown microfuses on the inverter board! I have fixed many of these and most have at least one shorted FET. After removing the 4 e-caps on the inverter, check for continuity across the two holes that each capacitor came out of. If there is continuity, you have a shorted FET. There are eight of them (8 pin surface mount chips)- four in a row on each side of the board. SMD chips are tricky to replace but it can be done. Search for 213T on the badcaps dot net forum for more info on the repair.

  8. Yes, That is true hopefully you can catch the problem and replace the caps before the FETs blow out but that would be the next thing to look at.

  10. Yes, That is a good indication that the capacitors are not holding the charge like they should be doing.

  14. You fixed one of our Samsung 214T monitors several years ago, and it is still working fine. We recently purchased a couple of capacitor kits for the 414T and installed one yesterday, with good results (as expected). Now we have a 213T wtih same problems. So the question is – Is the 214T adn 213T capacitor kit the same? Or are they different values, so we cannot us the 214T kit to fix our 213T. My technician that worked on them in the past is no longer working here.

    Thanks in advance,
