LG 20LS7D No Sound

I couldn't find a listing for the LG 20LS7D so I figured I would ask here.The problem I am having is there is no sound coming out of the TV. The picture is great but the issue is that there are actually no output A/V jacks on this set. When I hook up a DVD player to the back of the set it does not recognize that it is there either so I am thinking the whole board is bad. I have opened it up and inspected the board for burnt out capacitors or something and can not find anything noticeably wrong. The speakers are good so it is not them. Does anyone have any suggestions before I buy one with a broken LCD to steal the audio board from to fix it?

SOURCE: LG 5010 42" + Xbox360 + DVD RECIEVER/ Surround Sound SET UP HELP!

soulshaun:

I need some clarification before we can proceed. Which audio/video cable did you use to connect the 360 & your home theater receiver & TV/monitor? It makes a difference which you use. The HDMI cable would be the preferred one to use. The fact that the receiver only has 1 HDMI connection limits your options for other digital connections. Respond to this post & I can provide additional info. I have found that when responding to someone's question, I have a tendency to provide too much info on the 1st response.

peace-out

SOURCE: "No Signal" for PS3 using HDMI cable

jareddirk30:

you didn't mention what software version your ps3 is. in this digital age it's important to keep software levels up to date, with some exceptions. i'm including the web address for sony so you can update the ps3, but i don't think it's the problem. once you're are on their site you click on the ps3 picture & that link will take you to the software update pg. there you can review previous software updates. i quickly reviewed 1 of those & didn't see anything that addresses your problem.

http://www.us.playstation.com/Support/SystemUpdates

have you verified that the HDMI inputs are are enabled correctly? thereare 4 inputs. refer to pgs 25 & 26 of the owner's manual.

I would put the heat on your LG retailer. clearly the new main board is suspect. you had the functions prior to the swap. the board is probably defective, but with a different problem than what you had previously. i visited LG's site. they currently have nothing in their knowledge base that mentions the your problem, nor is there a software update.

if you need additional help. write back. good luck.

peace-out

At home I have cable and my TV skip a channel each time I press a channel up,and it can`t go up channel 11 for the rest of the channels list it couldn`t turn stereo to the red colour, please tell what...


Start by getting into the menu. You must be in the over the air mode to receive those channels you mentioned, and they are limited. Find antenna (on menu) and find cable mode ( hook up). Then program for auto channel search. Next, find the sound menu and find stereo mode. Thanks for asking and show all hands of support!

Screen on LG goes to black right after turned on.


It looks as if the backlights are being switched off at start up, this will be due to a fault either with the inverter board or a fault with the screens backlights which would mean the screen needing replaced. Contact your repair centre to have an engineer give you an estimate on the cost of repair.

Black screen on a 20ls7d LCD TV


I work at CNN Have had 6 of these monitors go out in as many months. Take out the power supply and change the 2 exploded 680u capacitors. They're being overheated by the underrated MOSFETs on the reverse side of the board. I'm looking for some substitute MOSFETs that handle power better; but replacing the caps will usually fix the problem. Otherwise replace the supply.

Lg 47 inch tv sound


We had the same problem of pathetic sound quality and volume with a sony brava. Thats just the way they make tv's these days because most people buy a surround sound system as well. We bought logitec computer surround sound speakers for about $140 and plugged into the ear jack, problem solved, we have heaps of volume and stacks of bass.

NO POWER


I ended up unplugging both sides of the power cord (from the TV and the wall), waiting five seconds, plugged it back it, and it worked fine.
