Samsung TV TXE2545 Bottom Half of Picture
Hi,
I have a Samsung TV TXE2545 mfg 4/97 in my shop with half a picture (bottom half) which is linear (normal). At the center (top of half of picture) is a bright horizontal line. Above, the screen is black. I scoped the input signal (pin 1) to IC301 TDA8350Q and it looks normal. Pins 4 and 8 have a little above normal voltage. Could the cause of this problem be IC301? Thanks in advance, Brad Before you type your password, credit card number, etc., be sure there is no active key logger (spyware) in your PC. |
