This is just a simple announcement that Coppell TV Repair LLC is now offering a repair service for power supply board DELTA DPS-171CP A and other boards based on PCB DPS-162KP-1 as shown on the image below. The following Sharp models are known to use DPS-171CP A:

• Sharp LC-70C7450U  
• Sharp LC-70C8470U 
• Sharp LC-70LE847U 
• Sharp LC-70LE745U 
• Sharp LC-70LE845

There are several different problems we've seen with this board.

One is where the board is totally dead and there is no +5V standby voltage. The TV is then totally dead, of course.

Another is failure to turn on upon being told so by the main board; this results in series of two fast and two slow blinks in the TV.

There sure are failures we have not seen yet.
