I have reprogramed a LG tv and it keeps says no signal after receiving 5 to 11 stations
Sounds like you need a better antenna or an amplifier for you antenna. But check first you antenna coax connection to make sure the electrical connections are tight. Also check your coax for breaks in continuity. You can do this with an Ohm meter. You should have near zero resistance center to center of the coax and same for the out shield. More likely the problem is not your coax but a weak signal from over the air. Also check to see that your antenna selector on your TV menu is not set to Cable but rather Air assuming your are wanting to pick up free over the air signals and not cable.

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Wont' turn on
Power supply or main board or microcontroller but you are not enough clear in your description of trouble! Best regsrds!

Lg 32in tv from 2007 wont come on ,only after sitting for 45 minutes and tuening it on and off will it come on
The fact that it comes on at all is a good sign.
Due to how long you've had it, my first suspicion is to check the capacitor in the power supply of the set. Over time, the capacitors will dry out. You'll need to remove the back and look at the power supply for bulging capacitors.
If you haven't had much experience with electronics before, here's a few tips.
Always have the power cord unplugged before opening up a TV...
The power supply is the first board that is connected to the power cord. The capacitors on the power supply board look like miniature soup cans and the tops of them should be perfectly flat. Some capacitors have a small x on the top, this is to allow expansion as the capacitor fails. Look at the top of the capacitors to see if you can see bulges in the top, those would be the first ones to suspect are bad.
Screen black fault
black after 15mins is psu fail
replace ALL the electrolytic capactiors on the psu
this includes the mains 350 or 400V types
then retry....
try to find any faulty CCFL tubes using there feedback
from each ccfl transformer
you could just find one tube has failed
look too you tube for CCFL replace etc etc
look more to a faulty single tube here
Why isnt my tv working cause i have took it to ary
Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
So the power light on the LG tv is blinking yellow real fast but the tv turns and stays on...is it just a warning or what?
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty
Tv how to troubleshoot tv lcd power supply
if your tv is an lg 32 3000 i have a working power supply for sale for 30 pounds and 8.50 postage however it could be swollen capacitors on your power supply which are easy to see that is causing your fault and if you can use a soldering iron you can replace these yourself but make sure you use the same value(uf) and voltage which is written on the side of them and also make sure you put them in the correct way round,,you can get replacement capacitors from maplins ,,RS components or ebay
I have sound but not picture
Tap on the screen with your finger end not to hard when the T.V. is on. If you see a white light flash, it means that the neon work, the backlight. So you should check your main board or your t-con board or a trouble in the power supply. Ask a technicien near you to check it. I would but i live to far. Best of Luck. Serge Lavallee.
Wheres the reset button on a lg tv 32lv3530-afb
To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
There is no external button marked "Reset"; to modern digital TVs.
