Question about Samsung HCL4715W 47" Rear Projection Television
Just before the extended warranty the converance went out and was replaced, now about 6 months later the set will not power up. Just looking for a little direction, I can do some repairs and troubleshooting myself and our local repair shop gave up without a repair schematic but I've located one and have a copy on hand. Thanks.
Check for a shorted transistor Q473, and R468 may be open as well (0.47 ohm @ 2 Watt). If it is shorted, try to find a good replacement part as the Samsung Part Aa96-00037a is No Longer Available. Also there is a possibility that the High Voltage block is also bad, if so, replace with Part Aa26-00101a. Good Luck!

Tips for a great answer:
Also, check if your unit is still under warranty/extended warranty
period, avail it because the manufacturer will fix it for free. Opening the
back cover will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
