Question about Toshiba 32A50 32" TV
The vertical output integrated circuit (Q301, mounted on a heatsink roughly in the middle of the main circuit board) isn't working. This is frequently because of bad solder connections, which is an easy repair if there are no other parts needing replacement. However, the device itself may have gone bad or there may be power supply problems. It's not unusual for other parts around the IC to go bad first and cause the IC to fail.
You can try resoldering the connections to Q301. If that doesn't bring the picture back, or there are other pictures problems afterward, you can see what a TV technician would charge to repair the set. I always liked the Toshiba picture quality, so if everything else was working properly and you were happy with the set it might be worth the cost of fixing it.
