Virtually unusable pictures, you will need to get better pictures. Common fault on this set is two bad caps.

Re: Bush LCD37TV016HD

Normally it gets blue standby LED which will go dark but then back to blue, after some time it may power up.

Re: Bush LCD37TV016HD

There is virtually no power at all,no standby nothing.

Re: Bush LCD37TV016HD

Have you checked for 5V standby from the PSU?

Re: Bush LCD37TV016HD

Tom i found a post which you put up about this lcd did your have the same symtoms,it was way back in 2011 your post.

Re: Bush LCD37TV016HD

Mine had a standby LED and powered on after about 20 minutes of flashing. I will not engage further until you make some attempt at testing things.

Re: Bush LCD37TV016HD

If ive tested it right there is not voltage running through the 5v,the board is a MLT198H,Ive uploaded maybe some clearer pictures.

Re: Bush LCD37TV016HD

Test each pin on this block connector on main board (top of image):

Voltage should be measured from each pin to the chassis ground.

Re: Bush LCD37TV016HD

What should each pin be measuring

[tom66]

Re: Bush LCD37TV016HD

I have absolutely no idea. However, I can make some educated guesses. Post your results.

Re: Bush LCD37TV016HD

cant get any reading,did check the fuse next to the where the power socket goes in,(clear fuse has small blob in middle of it ?

[tom66]

Re: Bush LCD37TV016HD

Please post your readings. Use DC20V. Saying you have "no reading" doesn't tell me enough.

[LEEDASH]

Re: Bush LCD37TV016HD

Ok,multimeter working,power cable working,tested and still no reading,dont even jump.

Re: Bush LCD37TV016HD

What is the meaning of NO READING? What exactly do you see on your meter?
