Hi Jestine ,

I Need Some Advice From You , I’m Looking For This Part No YC235 That The Code Writing On Top Of The Transistor For The Samsung 151V Model Inverter Board . Please Let Me Know Where I Can Get It Or Any Replacement For These Part No. Thanks

Hi ,
Mine was a YC141 transistor and i could not locate the YC235. Is your Yc235 transistor located at the high voltage transformer? It should have a pair on each transformer. It is a push pull transistor and i could not locate any electronic suppliers that sell this part. Try modify and put in a C5707 and test it out if you could not get the original part. Try replace all of the transistor (4 pcs). Hope this helps!
