Symptoms
A common problem seems to me now I was haunted too. On my Samsung SyncMaster 2493 HM delayed the start lately more dramatic. Today morning, I waited 14 minutes, until the screen finally built up a picture. At first I thought that to get a signal. Maybe an update of the graphics card's fault? But why is the screen starts then the longer the later? Strange.
Search problem
But after a short search on the Internet and many users of the Forum for computer base , which describe the same issue of the case was clear. There must be a defective capacitor act. So go ahead, screw on the screen depend on, and control. On the way to the culprit, I had to take a few hurdles. As always with such devices, there are Plastikhäklein that complicate an opening when you have time outside the four screws. Because, as attached, you do not see often. And yes it would destroy his beautiful piece either.
Suspicion is confirmed (Schrauberei can begin)
It was not until I screwed off the foot of the screen yet, is because it has a considerable weight and interfere with the work. Carefully then I clicked on the edge then dissolved with a small screwdriver into the compound and then gradually edge. Now they had to pull quite a few plug (hold good for photographs, for reassembly) to solve film and tape. Then came the turn of the intermediate principal piece. This board is screwed on it the other way around so you can not even see if a capacitor is faulty. So, there the four bolts off, the little sticky grid line and off the board (after all plugs are gone) Carefully remove. And lo and behold, actually stands out of the defective capacitor. Clearly visible through the abdomen and spilled media vaults. And what next?
Elko replace
First look at the electronics stores to call where it is exactly this type. It was on my a 10 volt capacitor with 2200 ㎌. Promptly had a TV commercial that offered to supply power and business savvy partner to me, it is also equal to solder. This is what I wanted at first myself, just can not go wrong a lot: Lötsstelle cold, wrong polarity when connecting, which can explode the capacitor to a hot soldering iron etc. 0815.
In the business meant that, at the Samsung is a known issue. He would use me, just a 25 V capacitor, so it will last longer. Within 5 minutes it was soldered to this and I could take that piece for a few francs to go home and install.
After I had everything back together and connected, I started the PC and waited anxiously for the result. And lo and behold, from the moment the picture was ready, and beamed at me. Of course, I beamed back!


Problem finally solved, thanks.
Hi!
I would replace the built-in Elko against adequate. As it stands, the new one is from the "general purpose" series by Panasonic. The durability will be modest, since this capacitor is not suitable for use in a switching power supply is optimal. There should be a "low-ESR" capacitor be used, preferably at 105 ° C operating temperature allowed.
Today I picked up the same monitor for repair of a friend and ended up with the research here. On another page the same for the whole Elkosätze be offered in the monitor power supply used.
Maybe I'm wrong but also, and the monitor has a little bit. Good luck and regards,
Kalle
Also from me a great thank you, that was for me the FAll. Fortunately, there is also a video guide how the zelegt. The television technician has soldered me a 40v, 5 € has cost the fun. Had to improvise a little, that the part is large but badly.
Thanks again for confirming my guess was the power supply and faulty capacitors.
The same model, same faulty capacitor.
Took one with 35V.
I recommend every one to take at least 2200μF 25V!
That should not last longer.
Now is the back.
And that is strange ..... again after 3 months warranty period. O_0
has also worked with me ...
Jo runs, perfectly again. They have earned a box of wheat.
They are already hinbekommen
Good luck!
Thanks, exactly the same problem with me. Let's see if our trainees turned out.
