This is a television/PC monitor that did not work after a storm. I expected to replace a few capacitors, but it only needed a single diode at the cost of twenty-nine cents and about an hour of labor. A new power board for this TV would have cost somewhere around $80.

This is the LG 17LX1R that will no longer turn on. Remove the cover from the stand by. Press down on the two tabs. The cover should come off easily.

Here is the removed diode. Description on the diode reads LT526 IN4007. Solder the new diode onto the power board. Use a pair of tweezers or hemostat to hold the diode in place while soldering. Once the diode is replaced, clean the board with isopropyl alcohol to get rid of any debris or old flux.
