Re: sharp LC-37SB24U will not power on

Yeah, I decided to go further with mine. I opened it up (behind the screen) and saw all the light tubes. They had no signs of darkening anywhere. When I'm doing the service mode combo on the buttons I sometimes wonder if I'm actually getting the TV into service mode.. just cant see it.

Re: sharp LC-37SB24U will not power on

Very interesting reading. [B]What does it generally mean if you cant see or get to the service menu? [/B]

Its been a while now.. but here is my story

I got my tv with the problem from my grandmother. (I might have been responsible for its fail in first place) She was having some problem, I dont remember now what, but I went in and did some tweaking in general settings, and I think.. I cant be sure but I'm positive I tried also to do a firmware update on the tv.

The tv started doing the blinking...

Re: sharp LC-37SB24U will not power on

I apologize then, as I said I'm not a hands on person, and when I reviewed through the service manual I saw the varying board diagrams, just did not take note that the power supply was not one of them.

On a side note : I sadly feel I'll probably have to chuck mine. I can never even get a service menu. I fear its probably not an issue with a board or element on the board, but probably a bad tube, and in that case probably not something I'd be comfortable getting into changing out.

Re: sharp LC-37SB24U will not power on

I do not need you to put things in bold for me, I clearly saw what TV the OP was talking about. I was simply trying to help and the research I found when I was looking for help had this to say :

"On the front cover of the LC-37SB24U Service Manual is the statement:

"This Service Manual covers the differences from LC-37D44U. For other technical information, refer to the LC-37D44U (S18D7LC37D44U) Service Manual."

The second line of the second link IS this manual. It appears to be...

Re: sharp LC-37SB24U will not power on

The way to find the service manual is you have to search for LC37D44U. I'll post up the service manual, if its not allowed then forgive my ignorance, I didn't see a post saying otherwise....

Re: sharp LC-37SB24U will not power on

Wow.. this is small world... I just joined today,I did a search for the model number of this board and this result comes up... crazy part is this is not a 2+ year old post.

I found the service manual for this device if you need it. It doesn't help me since I'm not really a hands on type guy ( though Id like to be)

Not to steal your post, but my device would blink both the OPC and Power button, first the OPC and Power would blink then just the Power.
