To my eyes it looks like two of the three capacitors on the center board next to the left hand heat sync are slightly swelled up.

Re: Sharp lc-37d40u help

I looked at the schematic I can't seem to find anything about a 1 blink code or for readings on how to check power supply for what pins is what voltages?

Re: Sharp lc-37d40u help

Page 43 for blinking code
Page 35, 36 for testing the voltages at the connectors.

Re: Sharp lc-37d40u help

budm when I look at page 43 it is blank for me. 42 and 44 is not blank but there is nothing on blinking codes, can you copy and paste me page 43 please?

Re: Sharp lc-37d40u help

nevermind bud m I got it, ok by my looks its says the only thing it could be is lamp failure? because the only thing that blinks is the green power 1 time , the onther blink codes says something like the power light must blink and the opc light, the only thing that flashes 1 blink is the power light so has to be lamp failure? im having a hard time understanding that chart if you could help?
