Question about LG 37LB1DA Television

1 Answer

Our LG 37LB1DA is scrolling through channels

Independently, out of the blue, it has begun to start scrolling through the channels, similar to a scan, however without any prompting from us. I try to turn it via the remote and although you can see the light flicker, it won't respond. It has once or twice turned off, only to turn back on by itself!
It's installed in a built-in cabinet in our kitchen and we're unable to reach the TV controls that are underneath the TV itself (that was well thought-out!) to be able to turn it off that way, also because of that mounting we can't pull the plug.

    thank you, since we're unable to unplug the tv (due to how it's installed in our kitchen), we'd have to shut off the breaker.Since you mentioned possible corrosion, it IS installed above our dishwasher so it's possible that the steam from the dry cycle could be the cause. None of this happened when we had the TV in another location of the house and it's only a couple of years old. We'll have to have someone check it out - thanks!

I have seen problems similar to yours in the past. Several causes can make the channels change by themselves. Some corrosion on the main board near the channel up/down switches for one. The next common cause is that the EPROM may be failing or a fault with the main control processor. A good test to see if the EPROM is having a problem is to program in all the channels off the cable and then unplug the TV over night and then plug back in the see if any channels are missing.

    Steam and moisture would definately cause some internal shortage. If
    your tv or comp monitor is outside for a few hours, You are supposed to
    wait almost a day for it to warm up and dry because they short out. So
    yes. them steam would cause internal problems. And it definately sounds
    like an internal short, probably on the main board.

I have a lg 37lb1da tv that is flashing red blue green when you turn it on

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. Viewing it in "Mosaic" or "Magazine" will make surf easy.
Blinking codes details to many popular brand TVs are given. Surf the site with patience. Do a search by type in the brand name of the device to the search box.

I have a Proview TV that we just bought from Rent A Center and when we connect our cable to the TV it tells us to scan the channels. We did this and still we get a blank blue screen that says No Signal....

Try this as your model is basically the same as mine.

Push Menu on your remote.
Then a small screen comes up.
Using your left right arrows move left to set up.
Scroll down to tuner mode and again using left right arrows, there are 4 setting you can choose. Once the setting you choose is showing then scroll up to Channel Searching and hit OK on your remote. This will scan all the channels Digital and Analog.

Depending on which of the 4 setting you picked on TUNER MODE you may have to do this again in the next mode to see which will get the most channels on your TV.

I hope this is helpful; Ken, Attica, NY
