Hi Jason, is your TV still under warranty? If so return it . The reason your not finding much info on the set is Hisense doesn't have the best customer service or that's what we have found. As long as the standby light is flashing you have standby voltage, next thing to test would be the voltage that tells the power board to come out of sleeping mode and turn on so the set can power up, most Hisense sets have it marked PON, you should see around 3 VDC there using frame as ground, if you don't see that voltage the main board has issues, if you get the voltage there the PMW circuitry should be working and the other voltages should be present. I'm going to have you test the power on pin and see if you have voltage there before going any farther Hi Jason, is your TV still under warranty? If so return it .

sadly it's out of warranty of 2 week i asked if i can still have one , and they said no. i changed the powerboard completly already , and the cable ( and power cable ) , i just received the mainboard but i didnt install it yet , the tv didnt get shock or something we just loss electricity and was connected on a powerbar ( i bought a better one with antisurge build in ) and i was tinking is really the mainboard was hit by a simple unexpected powerloss....... ?? are these hisense tv that fragile ?? , and hisense doesnt help much ive been dealing with them since 2 month and they just basicly told me to f*** off.... if i change the mainboard , and the light still blink the issue than will be a backlight strips ?? sadly it's out of warranty of 2 week i asked if i can still have one , and they said no. i changed the powerboard completly already , and the cable ( and power cable ) , i just received the mainboard but i didnt install it yet , the tv didnt get shock or something we just loss electricity and was connected on a powerbar ( i bought a better one with antisurge build in ) and i was tinking is really the mainboard was hit by a simple unexpected powerloss....... ?? are these hisense tv that fragile ?? , and hisense doesnt help much ive been dealing with them since 2 month and they just basicly told me to f*** off.... if i change the mainboard , and the light still blink the issue than will be a backlight strips ??

There was a chance of a power surge when the electricity went off, but that shouldn't have done anything to the main board, it could have damaged the power supply, but you have already changed that. Where did you buy the replacement board? Hopefully not ebay as it's a toss-up getting a working board or another defective one. Also, backlights shouldn't fail on a set with very low hours, it's possible but not probable. As long as you purchased a main board install it but I would be surprised if it helped, a simple voltage test would have told if it was working or not in the situation you have, the one I described in the last message.

i bought the board from CCSI – IT Products, Services & Solutions , good rating and i double checked and ppl bought hisense part from them and work great , is the backlight and burn if the tv close with a electricity loss ? , or the controller backlight maybe ? , it's weird how just because we loss electricity the tv is done , i double checked with all the reset and fresh install with the USB hisense gived to me , and nope , nothing work , ill change the mainboard tommorow , and if this blinking led still happend , the issue is maybe from a dead LED that didnt like to close to fast... ?? i bought the board from CCSI – IT Products, Services & Solutions , good rating and i double checked and ppl bought hisense part from them and work great , is the backlight and burn if the tv close with a electricity loss ? , or the controller backlight maybe ? , it's weird how just because we loss electricity the tv is done , i double checked with all the reset and fresh install with the USB hisense gived to me , and nope , nothing work , ill change the mainboard tommorow , and if this blinking led still happend , the issue is maybe from a dead LED that didnt like to close to fast... ??

No sure what you mean by "dead LED that didnt like to close to fast". I'm not familiar with CCSI but most companies that sell parts are ok, it's the fly by nighters on ebay that get sets that don't work and pull the boards out and sell them that aren't reputable. The backlight inverter is part of the main board, you replaced that so that should rule that out. If the main doesn't fix it, it will be time for some actual trouble shooting to find where the issue is at. Backlights shouldn't have failed from a power failure but with electronics anything is possible, over the last 40 years that I've been working on all types of electronics I've learned not to rule anything out No sure what you mean by "dead LED that didnt like to close to fast".
