Re: Samsung Syncmaster 932B

Thanks for the response PlainBill. I have read many of your posts on here and I think it is great of you to take so much of your time to share your extensive knowledge. I have re-soldered the transformer connections and measured the points indicated. I read open circuit on all points. I guess next time I will try to keep my picture ratio the same when I resize to avoid the funny oval caps

That does not make any sense. I seem to have omitted a vital bit of information. Set the DMM to the 2K ohms range. If all pins still read open, try the 20K range. If you cannot get a reading between the two pins circled in red or the two circled in blue on any range that would indicate the transformer is defective. They are available on eBay.

Request help on a Samsung 932B. I received it as a non working unit. When I went to test it it worked, but then quit after about 5 minutes. I opened it up a discovered that one set of lamps flashes on for a fraction of a second while the other remains dark. I have a a pair of lamps(total 4 ccfl) that I then used to test with the same results no matter which lamps were plugged in , only one plug on the board would flash momentarily. I believe it may be a transformer problem but I am not sure. Thank you in advance. Sorry if photos are not great, help me get better.

Interesting pictures. It's unusual to see a monitor with oval caps. :

The symptoms indicate a defective inverter transformer or possibly bad solder joints. I've marked up the picture. Measure the resistance between the pins circled in red and between the pins circled in blue. It is not necessary to remove the transformer for this test.
