Re: Samsung 2233RZ "2s to blanck"
No I made it, because I'm a moron, I read "SOLDER" and I tried de-soldering there on front of the board at first. Don't laught at me
My stupid action maybe burnt the secondary wiring, I agree on this.
thank you. Hopefully it'll arrive in 15 days. I'll report back....Leave a comment:

Re: Samsung 2233RZ "2s to blanck"
sorry for that. I'm uploading detail of the bronzed part. Doesn't look too bad to me, too. The bronzed part is only a bit darker on the back of the board, near primary pins of the transformer and near right one (upper left transformer pins of first photo). On the board front no burns are visible (a part from my soldering mistake near the "SOLDER" label :/ ). The screen was used for about 6 hours per day for a year and half, then started going black after 2 sec.
No, they're the original...Last edited by shineangelic; 07-31-2012, 03:31 PM.Leave a comment:

Re: Samsung 2233RZ "2s to blanck"
It was on 200 ohms, because at 2000 the reading was 0. I confirm it, at 20K the reading is 0. All other contacts coupled give "1". I repeat, I totally broke the transformer magnet when I removed it. Lol, I read "SOLDER" and thought I had to solder there. I'm a moron.
Sorry which transistor? Do I have to read the resistance between base and collector? At 2000 ohms? Sorry I'm a complete noob at electronic repairs. Anyway, I'm quite determined because I payed much for this...Last edited by shineangelic; 07-31-2012, 03:35 PM.Leave a comment:

Re: Samsung 2233RZ "2s to blanck"
Ok, I uploaded the power board images. On the back of it there is a "bronzed" area...I wonder if that could be a problem.
I already bought a new TM-0915 transformer, because desoldering it I broke the magnet
I could post the resistance recordings, but I guess that without the magnet they're altered..All "S" contacts seem to be open, as the multimeter reads "1". The only two contacts that give a reading are P1 to P3 = 0.6ohms
Please let me know if photo quality...Leave a comment:

Ok, thank you for reply and attached image, I needed it. This evening I'll test it and report back....Leave a comment:

Re: Samsung 2233RZ "2s to blanck"
I'm electronic noob with same problem. I removed the transformer after reading this thread, since the capacitors look good. I can't understand how/where to measure resistances. What is P1/S1/P2/S2?
I see a total of 10 pins on the back of the transormer, exactly as in previous post's attached image:
Could you please "bind" P/S labels to the image, so that i can measure resistances and report back ? Thank you...Leave a comment:
