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. http://electronicshelponline.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.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

My screen will not turn on even tho there is power?


Just repaired this TV today. You will need to purchase the inverter board. The TV will power up....you will see "PLEASES WAIT", and disappear, you have a black screen. When you remove the back cover, look to your left. You will see a long vertical board. That is the board you will replace. Seek shop jimmy, enter model number of your TV. You will see an inverter board for $24.95 plus $9.50 shipping. Thanks for asking me, Matt of Martins TV Repair.

Dynex dx-40L261A12 won't turn on. Red power light is on, but no sound from speakers and no picture. Remote power button and power button on tv doesn't turn the tv on.


In this case, the symptoms you describe is a faulty inverter board. The TV will or should flash "PLEASE WAIT" and then you have a black screen no audio. Find Shop Jimmy on line. Enter your TV model number. You will find an inverter board for $24.95 plus $9.50 shipping. When you remove the back cover of the TV, look to the left. You will see a long vertical board...this is what you will replace. Thanks for asking, Matt of Martins TV Repair.

Have a Dynex, Model: DX -55L150A11..................The problem is that it constantly shuts off. Sometimes- when I'm curious about the end of a movie- I unplug it for about 10 mins and that works


Ya its the power supply board . the other guy wrote a book about old tvs talking out of his rear end.... Newer tvs are easy to fix as long as the screen isn't broken . I personally know about dynex tvs and there flaws . I repaired my 55in dynex . it was a easy cheap fix
