Re: Help with sharp 46d82u

no the other end does not have any markings, although i have not taking the main board out of the unit to see the back of it but i pulled the power board out and it has no markings. i have attached some pics of the rear of the unit, the main board, the power board and also the pins between both of them i checked for voltage at....

When plugged in the relay clicks on and off a few times then i get the power and opc blink once and then the green power blinks twice by itself. by reading the service manual i believe this is the "Initial communication from the main CPU is not received". I have the service manual but I've never dug this deep into elactronics before (i'm quite savvy and have worked with ac/dc voltage alot.) i have tested the power 12 pin "PH" pin going to the main board and this is the readings i'm getting when trying to power on:
1- 12.4v
2- 0
3- 0
4- 0
5-...

Im Josh. I like tinkering with electronics, I have alot of experience with ac/dc voltage over the years, I'm a heavy duty mechanic and welder by trade. I'm wanting to learn more about smaller electronics so I can repair stuff myself so forgive me in advance if I happen to ask a "stupid" question.

Re: Sharp LC-32D44U (3 power 1 opc blinks)

sorry to bring an old thread back to life, but i'm having the same issue with a sharp lc-46d82u. when plugged in the relay clicks on and off a few times then i get the power and opc blink once and then the green power blinks twice by itself. by reading the service manual i believe this is the same error code?i have the service manual but I've never dug this deep into elactronics before (i'm quite savvy and have worked with ac/dc voltage alot.) i have tested the power 12 pin "PH" pin going to the main board and this is the readings...
