I have a Sharp LC-43UB30U which was purchased in 2015. The tv now makes loud crackling/popping noises, The tv turns itself off and on and at times goes either to an all black screen or a screen with snow or just goes off completely. Do you know if this could be the power supply?

Hello I have a Sharp LC-52LE640U and it won't stay on. It will turn on for a few minutes then go all black or turn off. Then it will keep trying to turn on by itself it seems. I did the backlight test like suggested but its not showing up so i dont think its the backlight. Is there a specific resistor i can change out. I see the main board on your web site is out of stock. Thanks for the help!

[dukerambleton]

Thank you. You help me keep my tv going.

My Sharp LC-70LE660U tv has no picture (very dim blue light in the background) or sound when turns on. The white power light comes on while it could not be turned off either by remote control device or from the tv panel button. I have unplugged power cord and no success to get the picture on.
Please advise if this is the problem of backlight inverter or the power supply board? Thanks.

Helpful thank you. My Sharp Aquos has sound but no picture. Is it the mother board I need to replace or something else? Problem has been intermittent since purchase (2nd hand) and could be "fixed" by turning tv on and off several times or leaving for 10 minutes and then turning on and off. But last three days it's taken most of the day for it to finally come on (still by turning on and off with the remote). I might not tackle the fix but happy to purchase the part for someone else to do. Thanks,

Hey bud I have a LC - 70le735u sharp and when I plug it in it blinks 1 quick 1 long and the repeats what can I do

[bretward]

I have a Sharp LC-46SV50U. It doesn't always come on when the power button is pressed, although the green led comes on and stays on. When in this condition, the green light is on, the tv cannot be turned off with the remote control. Other times it the tv comes on as it should and functions normally. I have always been able to unplug the power cord, then plug it back in, press power and get it to come on normally. However, I may have to repeat the sequence of unplugging and plugging back in and pushing the power button several times before it will come on. As I said earlier, once it comes on it will stay on and work as it should until manually powered off. The green or red light never blinks. Can you please help me?

My Sharp 60" LC-60LE745U wont power on. The arrow-shaped light under the screen flashes twice fast and twice slowly. No picture, no sound, no backlight. I've gone through all of the button-pushing sequences that I've seen online and in the comments but nothing works for me. Any advice? Power supply? Would I get the flashing arrow lights if the power supply was bad?

Tried all the tricks, unplug, hold power on, arrow up, (do a backflip while holding my breath and singing yankee doodle) etc. Does it sound like it needs a power supply board replacement?

Hello, I have a Sharp TV, model LC-46SB57UN that will not turn on. It has the power light, OPC light that blinks twice together and the OPC light blinks once by itself. Could this also be a result of a bad power supply board?

[robsessions]

I have a Sharp lc60le600u TV that will no longer turn on. I bought this TV used, and it powered on just fine when I bought it, but after letting it sit for 3 days without powering on, it no longer displays anything. When I initially plug in the TV the V power light in the middle of the TV (under the sharp logo) illuminates for a few seconds and then goes dark. The power button doesn't do anything for the screen no does the affect the lit up V. I'm thinking the power supply may just be bad but I'd like to hear what you think is the issue. Thanks!
