Lg tv: 37lg30 st-by indicator on but don't start up

Check on the back of the TV to see if you have a "remote in" port. It will look the same as a 3.5mm headphone jack. Unplug the TV and plug a pair of headphone into the port and then remove it. Do this several times to breakup any debris that may have gotten into it or corrosion that may have occurred in the port. If something is in the port it will disable the standard remote sensor on the TV.

Andrea, not 100% certain what your issue is. But, I have used a company named ShopJimmy.com in the past with great success for my parts. I included a link to your model page from their site. Hope that helps!

Hi there,
They sell LG screen parts at:

http://www.alllgparts.com/

Just type in the model number on the left hand side, under appliance search and it should list the parts they have in stock.

Hope that helps.

37LG30 - loosened the 4 screws on the back of the TV but base mount wouldn't come off. Found that had to remove the screws even though already loose so that doesn't bind in the holes. Did this by making the loose screws bind in the wholes. Using twisers in the whole would have done the same thing. o

Must be the IR receiver usually is soldered on a circuit board. Time to call your warranty..

Most preset codes are 1234 or 0000 or 5555 and 8888 these are not srevice codes

my lg tv don"t have picture just sound,what can i press on the controlpanel?

This is more probably a software fault within the TV. They need instructions for HDMI inputs & a no sound is a related fault. I would get in touch with your dealer to arrange the TV to be updated to cure this problem. Hope this helps.

Why not buy a new universal remote and programe it for both devices
