There are possibly several different boards for each model TV. All items are tested and guaranteed to work. All of our parts are reclaimed FROM WORKING USED OR NEW BROKEN SCREEN TV’S. We reclaimed them from working damaged TV’s. THIS IS NORMALLY HOW YOUR TV WORKS (simplified). When you plug in your TV a red light comes on (called a standby light). When you turn on the TV a signal is sent from the power supply to the main board, it checks the circuits if, OK, it sends a signal back to the power supply to raise the voltage on the large capacitors from 180 to 360 volts and turns on the rest of the TV. ALL BACKLIGHTS ARE TESTED IN THE TV AND WHEN REMOVED FROM THE TV. PLEASE NOTE: There may be more than one different set of LED strips for this model. Please confirm that XXXXXXXXXXXX can be found printed on your original LED strips before ordering. IMPORTANT: Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen). ORDER BY THE RSAG7/820. XXXXX NUMBER, ORDER BY THE SIX DIDGET NUMBER ON THE WHITE STICKER ON THE BOARD. Symptom: TV has sound, but no picture or looks like it is coming onfrom the light(s) on the front panel, but the screen is dark or there is no picture. Tip: Try shining a light on the front of the TV after you turn it on. Do you see a faint picture? If not, it may just need a circuit board replacement. If you do see a picture, then the back lights is most likely that powers the back lights is at fault. Symptom:TV is dead. There are no lights that come on anywhere when you plug the TV in to a power outlet and press the power button. Tip: This can be caused by a blown fuse from a surge or lightning, but most often it is caused by a defective main board. Symptom The TV light flickers on and off this is normally a back light problem, sometimes the power light will change from red to blue you can normally verify this by testing the voltage on the large capacitors on the power supply it should be about 360 volts (CAREFULL). Symptom: the red light does not change colour, this may be a power supply or back light problem if there is a short on the back lights the main board will shut the TV down (a safety feature to prevent fires) try disconnecting the back lights and testing the 360 voltage. Symptom:The HDMI ports are not functioning or not functioning properly. Tip:Most often, the problem is with the main board. Most main boards contain all of the HDMI ports, so replacing it will fix the problem 98 percent of the time. HDMI ports are often damaged by lightning. The top tech reports that about half the jobs he assesses that have lightning damage involve main board replacement because HDMI ports are non-functional even though the rest of the TV operates normally. Symptom:The TV appears to be in an endless cycle of coming on and going off by itself showing the logo only. Sometimes the cycle ends with the TV staying on or going off. This is normally a main board problem. Note: when changing the back lights: the screens on the TV is very fragile and would suggest you watch a video on u tube before attempting. When changing the back lights on 55 inch and up screens: they are extremely difficult to change and require two people and four suction cups: One model of TV uses different back lights so check the part number on the back light strip before ordering. IMPORTANT ALL MAIN BOARDS MUST BE UPGRADED TO FUNCTION PROPERLY FAILURE TO DO SO WILL APPEAR AS A DEFECTIVE BOARD. Changing a part on a TV is not like changing a light bulb most TV’s are software driven and require an upgrade from the mfg (to match the new part to your TV) without this upgrade your back lights, WiFi, sound etc may not work properly or fail prematurely. If you have vertical or horizontal lines on the screen it is a screen problem, changing the t-con will not help. These are suggested tips only and are not always the solution TO ALL PROBLEMS. PLEASE NOTE: BECAUSE THE PART YOU ORDERED DID NOT FIX THE PROBLEM DOES NOT MEAN IT WAS DEFECTIVE EVEN THE MOST EXPERIENCED TEC DOES NOT ALWAYS MAKE THE PROPER DIAGNOSIS WE ARE NOT EXPECTING THIS OF YOU.
