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.

Hello Kenny

Please follow the steps below with you Sky remote.

RED + SELECT (flashes twice)

Try the volume button if this works then press the SELECT button on the remote. If not press the TV button and try the volume again. repeat this step until the volume works the tv then remember to press the SELECT button to save the code to the remote.

If for any reason this does not work then what I would like you to do is take the battery cover off the remote. You will see a label on there stating what REV 4,6,8 it is. The numbers indicate how old the sky remote is. If your LG telly is a newer tv then you may need to purchase a newer Rev sky remote.

The above should sort you out no Problem Kenny
When it does please leave a thumbs up

This is likely due to a failed power supply. Replacing the power supply board should solve the problem.
