Question about LG RZ-37LZ55 37 in. HD-Ready LCD Television
Our LG LCD RZ-37LZ55 wont turn onoff. The red/green standby light just keeps turning on and off with no picture and no response to the remote
One common part failure in the LG RZ-37LZ55 that can cause the symptoms you are describing is that the IC904 on the power card becomes damaged. In fact it is not uncommon for this part to burn a hole in its middle obscuring the part number! For your reference, the complete part number is STR-T2268 / 5907.
Not that this is the only thing that can go wrong with your TV's power supply - if you are handy I would definitely advise you to start with the power supply board of your set, looking for visible damage.
If you are not experienced with safe practice around the high voltages present in a television, please consider taking your set in for professional troubleshooting and servicing.
I hope that helps.
