I have a Magnavox 37MF32id137 we turned the tv off on the front went back about 25 min. later and it would not turn back on there is a dim green light flashing but has not turned back on in the last 24 hours 1. whats wrong and 2nd what kind of cost are we looking at. Phil

check the lamp first to see if intact or shattered.

Although a capacitor may look good, it may be weak or bad. Here is what you will have to do. Replace capacitor (location) 2074 which is a 25 volt 2200Mf at 105 degrees. Replace capacitor (location) 2081 which is a 35 volt 1200 Mf at 105 degrees. And you should change capacitor 2066 which is a 16 volt 10Mf at 105 degrees. Please be careful with the last cap mentioned. You can easily tear the PCB trace if you are not extremely careful. This should bring your TV back to life. Thanks for asking and show a few hands of support!

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

unplug the tv, wait 5 mins plug it back in, and without using the remote, press the tv on button. see if its ok.

If those green lights on the board are going dim, then yes it should be repaired. This is likely a bad main filter capacitor on the primary side of the switch mode transformer. Should not cost over $150 at the most. Easy fix

Also changed swollen C2074 and C2081 and it now works perfectly! a bit daunting for a novice like myself but with a steady hand and decent 'put it back the way you took it apart' skills, all went well!

the automatic code is actived.

No, if the picture of your tv screen is clear when when you watching. the troble of your tv is looseboard, and you replace your CRT socket too.
