There are two types of reset to TVs. The first is simple to do; a Hard Reset; and 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; will be better. 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; check the site linked here.

Good day!!!

Sorry for the late response because my internet connections got problem hope you understand..

OK,First thing I need to know if the board on the picture in the forum is the original board of your TV or it is the board you purchase..

If that is the board you purchase I think that board is the exact replacement however it different on the version of said board..so that the TV works fine but the remote is not function..Or the IR is bad..

try to see the version on the original board to the new purchase board if the same..

check the encircle part of main board need to compare..


If they are the same the problem I see is the IR sensor try to clean it first including the glass protector before you replace it..

But if the problem is different version no choice you need to replace the board or contact the store where you buy it and ask for replacement..

Just keep on touch to fix the problem..

Hope it helps
thank you

I recently repaired 2 LCDs that would not imidiatly turn on when the power button was pressed. It took the first one 5-10 cycles before it would start, and the little one took about a half hour. I removed the back and found that a few components were bad on the inverter portion of the board and replaced them with corrisponding parts from a local electornics store and they both started first try everytime. If you have the tinkering spirit and for the price of a soldering station some desolder braid and some solder you could fix your problem today.

Just make sure it is unplugged!

It appears that your are having a tube failure issue.

Either that, or you have a capacitor problem.

Both can act like that, but as a rule the tube acts more like that when it fails than the other parts of the tv.

The tubes are replaceable, and are available from Fry's and BestBuy.

If it winds up that it is the capacitors instead, then I would take the tv to either Fry's, BestBuy, or RadioShack.
These companies have specially trained techs for just that repair, as it takes special skills to deal with the voltage and power that capacitors can hold in them.

I hope that this helps you out some, and good luck!

Off brand televisions have problems with the engineering behind their components. You will need to look for popped or buldged capacitors on the power supply mainly! Also look for any burnt resistors as these also over heat and will pop capacitors.

Please rate if this was helpful!
