Magnavox Model 37MF32ID/37 Flatscreen TV - When the power button is pushed either on the remote or on the TV, nothing will come on. Sometimes the green power light flashes a little faster than 1 time per second and other times the power light doesn't come on at all. I've tried unplugging it for a while, and also unplugging it and holding down the power button, then plugging it back in. It has been acting up for about a month, at first, it would come on if it was unplugged then plugged back in or the power button was pushed and then when it quit flashing pushed again sometimes it took 5 or 6 times before it would come on.
Fault to the main power supply regulator section. 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. http://electro-medical.blogspot.com/
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.

Helpful Resources for Magnavox TV codes. Press and hold ... Note: If some buttonsdo not operate your equipment, try one of the other codes for your brand. TV.
It looks like there might be some dry/cold solder joints in the TV circuitry.
I would suggest to check those solder joints, specially around high power resistors in the power supply area using a inspection tool such as a magnifier with power magnification of 2X to 4X.
I provide this information for those that are qualified and trained to do TV repair work. Entering or making changes in service mode by untrained persons can cause significant and permanent damage to your television. If you are not qualified to service your television, please DO NOT ENTER these service menu codes

You need to check power rails and look for bulging capacitors near heat sources. I hope I have been of help but please do not hesitate to ask if you have any further questions. I appreciate your vote if you appreciate my reply.
This problems,very common in LCD tv,after the tv was in used about a year or two.The new technalogy LCD tv don't handle heat very well,not like the old CRT Tube Tvs.The power supply board tend to have bad capacitors componnents leakage,that bulges up it top or puff up gases escape,that why it take times or couples pushes to the power botton to turn the tv on.U know basic electronic's,and have soldering tools and solders?Take the tv aparts,check for these bad capacitors,that bulges,puff up in the power supply board and replaced them,than ur power will work normal again.Or tries Websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
