I'm looking for a replacement transformer for a 27" Symphonic
television. Model number WF2702. The transformer sits at a location marked T601 between the primary and secondary power block. Currently it is emitting a high pitched whine when power is applied to the TV and the TV will no longer power on. The following numbers are located on a sticker on top of the transformer: 00CPSA099 SA003D SA 25TD It's about 1 1/2" wide, 1" deep, and about 2 inches tall. Black plastic with yellow tape wrapped around it. I've tried contacting Funai Corp (the manufacturer), however, their customer support people (who seem to actually respond to emails) won't help with parts related matters and their parts department takes forever to respond to emails (3+ weeks). So I'm looking for alternative sources to find a replacemnt if anybody knows of one. |

The squeal from the transformer is caused by an overload on the power
supply. In-depth troubleshooting is required to find what is causing the overload, including disconnecting active devices like the horizontal and HV sections, etc. I'll bet you will eventually find something shorted. wrote in message ups.com...

First, I'd like to thank everyone who replied in such a short time and apologize for my delay in getting back to everyone. I pulled the transformer out of the TV before I saw the replies trying to find a part number on this transformer after being told my a couple of Symphonic's local authorized support centers that the numbers on top weren't a part number. After several emails with Symphonic support, I finally found out that I did have the right numbers and that it's a $3 part. I haven't ordered it yet however. I gave up at one point on getting this fixed and was looking into buying a Westinghouse 1080p Monitor. However, the w1 revision is at the end of it's run and BestBuy (pretty much the only retailer) isn't getting any new ones until the w2 revision comes out next month. In the meantime, I thought about seeing what I can do with the TV I have before tossing it to the curb. I'm considering ordering a new transformer since I already have it sitting here on the desk next to me. In the meantime,I think I'll take a multi-meter to the primary supply side and see if I can find anything that's not reading as it should. Any guidance here would be appreciated. Thanks again everyone.... |
