Watching my LG 37LC2D and suddenly a loud 'pop' sound,screen goes purple,then blank - no picture, no sound. I turn off TV and power, wait a while, turn it back on - after a couple of minutes the picture...

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; [Exclude the model number], in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My 37LC2D takes about seven minutes to come on after I turn the unit on. There is a red flashing light on the lower right hand side of the screen.

Does the unit work ok when it eventualy starts up? if so it would suggest possible dry solder joints in the power supply section, high value resistors that have changed tolerance,dried out capacitors? but if this was the case you would expect to see some visual picture problem, picture size problem or an audio hum?? these type of faults you would expect to see with age, ie if the unit was 3/4 yrs old. You will need a techie visit,sorry.

Check for a popped capacitor on the power board. They are the round tube looking things with a cross or cross type shape on the silver flat top. Check they have not leaked and are still flat topped. The one your looking for is about 8mm diameter on right hand board. Take the back off, i suggest putting it face down on a mattress with a blanket support. Take care not to lean on it. When the backs off you will see 3 circuit boards the power board is the smaller of the 3 on the left, looking from behind. Good luck.
