Question about LG 32LC7D Television

1 Answer

No picture on startup and random remote cntrl functions stop working

Multiple problems with an LG LCD 32LT7: 1. Intermittently will have no picture or no picture and sound on startup. Problem temporarily fixed by cycling off/on. 2. Remote will intermittently have several functions stop working. The TV sensor still receives (red light blinks ok). The off button on the remote usually still works and again - problem temporarily fixed by cycling off/on. 3. Sometimes gets random "schedule record errors" when recording programs to the inbuilt Hard Drive. There are other quirky little errors that are similar to the ones described, but the above 3 are the main problems. Any ideas? Do multiple errors point to a software error? Thanks, Adam

    Thanks pilot210 - your idea is a little too technical a solution for my skills I think.

    Update: the remote now does not work at all.
    Remote reset no fix.
    New batteries no fix.
    using remote 1 inch from the sensor still doesn't work.
    Remote still has LEDs flashing when buttons are pressed.

    Again: this is an LG LCD 32LT7, not the model stated in the category.

    very strange... anybody?

Common problem on this set is the main board p/n AGF33761101. However, you might try a 'quick fix' mod on this set which involves locating and bypassing components.

I do think that the replacement board just have these 4 coils bypassed on them already, so you might be able to save some $$$ if you're electronics-savvy by removing and discarding coils l4010, l4011, l4012 and l4203... then jump the solder pads they were on with small bits of wire, making very sure not to short to ground. Good luck!

I would go out and get a replacement Universal remote with menu keys. Set the code for your TV and try that. You may need to activate the menu with the old remote and then do the adjustments with the Universal remote. Older sets work with most Universal remotes real well. make sure you get a remote that supports MENU functions.

LG Television 37LB4D "Rebooting"


Ours is crapping out just like yours. Picture goes out, "black and white squiggles" appear in the top left of the screen then TV input appears, then it either repeats or gives me my picture back. This happens with both the HDMI slots (tested all 3) and both Component slots. Seems like the bulb or a circuit board on the TV is faulty. What a piece of ****, never spending another dime on LG products. I did get it to come back by hitting the back of the TV with a good slap, but it gets really annoying.

Tv turns off randomly


it is possible your neighbor has a universal remote and is playing tricks on you, or it could be over heating problems.

If everything else on the remote works, most likely the PWR function on the remote is not working.

This may be a problem with the conductive rubber membrane under the button, or the matracy circuit is not reading the function due to any number of problems.

You can call the manufacture parts rep to see if it is possible to have parts for the remote. Most of the time, they are not worth to service, and parts are not sold to support remote control service. You will most likely have to order a new remote from the manufacture rep.

I suggest to NOT buy a universal remote. They rarely can do more than the most basic functions. Many times universal remotes have different issues with different models of sets.
