Have a Magnavox 37mf321d LCD TV, one day, went to turn it on, and the green power light came on, along with the screen (which just flashed), and then went off. Waited a few seconds and tried again, the same thing happened again, only this time the green light and screen flashed about 15 times, and then stopped. Every time I turn it on the same things happens, if it has been sitting a more than 10 mins or so, one flash then off. If I try it again, it flashes between 10-25 times, the number is always random. I have tried resetting the TV, changing power cords, plugging directly into the wall to rule out a bad surge protector, and I have taken the back off and looked for popped capacitors. I tested the fuse on the power supply board, it is good.

hello this question is for maatmartin7 you gave advice on replacing capacitors... 2200Mf or 2200uf whats difference between Mf and uf caps i did the cap change out from a different advisor but with uf caps is this a problem... i had the green light flashing symptom for a long time i just kept pushing tv to turn on..now i just get a backlight of the screen for a few seconds then nothing else no indicator light stays on just blank. is there a way to test a power supply board befor putting the tv back together? thanks for any response hello this question is for maatmartin7 you gave advice on replacing capacitors... 2200Mf or 2200uf whats difference between Mf and uf caps i did the cap change out from a different advisor but with uf caps is this a problem... i had the green light flashing symptom for a long time i just kept pushing tv to turn on..now i just get a backlight of the screen for a few seconds then nothing else no indicator light stays on just blank. is there a way to test a power supply board befor putting the tv back together? thanks for any response

The uf is the symbol for microfarads. Yes you did fine by using them. Remember you should replace two caps. The 35 volt 1200Mf and the 25 volt 2200mf. Be sure you are using the 105 degree temperature caps and you have the correct polarity. And the las tcap use caution upon removal and that one is the 16 volt 10 mf. Be sure you inspect any and all grounds. You may have to double check your work. If you have an ESR meter you may find another weak capacitor. But you will have to search. The ESR meter is your capacitor tester. Thanks for asking! The uf is the symbol for microfarads. Yes you did fine by using them. Remember you should replace two caps.
