Sharp LC-46SB54U No Power

[raykia]

hey all,

is there a list that shows the blinking light pattern for a Sharp LC-46SB54U??

I have the power light and opc lights the pair blinks twice then only the opc blinks once

if some one has a list of all the blinking light patterns that can shoot my way thanks. The service manuals don't list it.

thanks

Thanks budm

I have the service manual just wish that it included the power and opc flashing code list for sharp. I have been looking hi and low for them

It may have the same codes as used in SB55U.

Re: Sharp LC-46SB54U No Power

thats what i was looking for thanks helps narrowing down the issue(s) may not be worth it due to lightning strike

Lighting strike, more likely taken out the HDMI IC also.

Yeah had one before on a plasma Vizio


I'm leaning toward main board with a faulty 15v detection circuit on main board. 15 v is present for a brief moment from power board haven't tested for short on ic1604 (hdmi) yet plus I need to isolate psb and force it on to to make sure it is functioning correctly
