First, you as the purchaser of the part is accepting the role of the technician in properly diagnosing and installing the part. We do not know your qualifications as such. Secondly, each part we sell came from a TV that had a broken or defective LCD or Plasma panel. Any questionable boards are disposed of.

NOTE;CHECK DIAGNOSTIC TIPS BEFORE ORDERING. Please be sure that the BOARD Part Number AND SERIAL NUMBER are EXACT to the one you are ordering, some models have different boards. Do not match by TV Model. There are possibly several different boards for each model TV. All items are tested and guaranteed to work. The majority of our parts are reclaimed FROM WORKING BROKEN SCREEN TV’S. We do not have NEW PARTS. 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. 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 backlight 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 backlight problem if there is a short on the backlights the main board will shut the tv down (a safety feature to prevent fires) try disconnecting the backlights 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 backlights: the screens on the tv is very fragile and would suggest you watch a video on u tube before attempting. When changing the backlights 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 backlights so check the part number on the backlight strip before ordering. 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.
