LG LCD TV picture will not come up, but have sound.

I have an LG LCD TV and cable attached to it. I'm having problems getting the picture to come up. I have sound. After turning the unit and off from the remote and from the tv it finally comes up. When it on there the picture is perfect. It just when the tv is on for several hours I have problems getting the picture to come up. Do you know what the problem maybe. I've owned the tv 3 to 4 years and never had a problem with it. Thanks!

If your Tv does that after certain period of time you need to replace the mainboard, the mainboard is the one where you plug everything, cable, antenna, video.

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

47LG70 - PICTURE WENT OUT. STILL HAVE SOUND. HEARD A POPPING NOISE WHEN PICTURE WENT. TV IS ONLY 1 1/2 YEARS OLD. ANY IDEAS WHAT MAY OF HAPPENED.


I have had the same problem off and on with my 47LG70 for months. When the "popping" noise happens, the blue light in the corner stays on, so I know the tv is still on (sometimes I still have sound, sometimes I don't). Sometimes the screen goes black, but other times it is blue. If I turn the tv off then on again, it might stay on for seconds, minutes or hours. It's been very frustrating.

This seemed to happen right after I got my new Comcast box, which came with an HDMI 1.3 cable. I read somewhere online that this tv might not be compatible with that cable, so I unplugged it and am using component cables again. I just did this today, so I don't know if it will work, but so far the tv has been on for 30 minutes with no problems.

I'm pretty ignorant about HDMI compared to component cables. I imagine I will not get as good a picture with the component cables, but I am willing to sacrifice quality if I can just get the darn thing to work. Mine is also only 18 months old.

Hope this helps. If it doesn't, maybe someone else out there can help us both.

Connecting a DVD/VCR combo to LCD TV


The best suggestion I would advise is to buy a shielded scart connector & connect that from your DVD combi to either AV1 OR AV2. It sounds as if you are picking up RF interference from your current connections, this can sometimes happen if the cables do not have adequate shielding.

LG LCD HDTV 'NO SIGNAL'


To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.

If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.

All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru
