LCD Monitor Problem Solved!

By on May 30, 2008

Here is the question again from my subscriber:

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!



Today i got this email from the subscriber again:

Hi Jestine ,

The transistor YC235 change to C5707 it really work , now the lcd back to normal . Thank a lot !

Note: So please take note to all my readers, you can also substitute the YC141 with C5707 too!
