TV/Monitor help.. randomly turns off

AnbuItachi 1,532 36 August 11, 2015 at 03:03 AM
I have LG TV 32LN5300 using as my monitor for computer (win 7). Issue is the monitor randomly shuts off/screen blackens, red light starts blinking and about 5-30 seconds later it turns back on. I have no control over it if it auto shuts off. This repeats like every 5-20 minutes. Sometimes I'd get 5 turn offs in like 5 minutes, other times I go the hour with 1 turn off. How do I fix this?? I tried replugging everything but still happening. (It turned off twice as I was typing this -_-)

If you change it to something else like the tuner does it still do this or only the input with the computer on it?

Have you checked the energy conservation features of the TV? If it's new you might call or send LG an email. It's possible if it's a bug as someone suggested there is a firmware fix available or in the works.

Its a TV so it has a tuner... You don't need cable but the point is does it do it only do it over HDMI or everything.

Can you count the number of blinks from the red LED light. This could be a blink code telling you what the error is with your TV/Monitor.

I tried finding info regarding # of blinks but didn't find much. There are 4 blinks. Then goes to a standing red light, then continueing 4 blinks, until it recovers and turns back on.

The best advice might be to get a proper computer monitor.

I'd suspect overheating or some type of power regulation issue.

what? aren't TVs superior to regular monitors. Why would TVs overheat when connected to a computer?

you could check the capacitors, but other then that your better off getting a new tv or a real monitor.

No, the only advantage they have is that they are larger. When used as a monitor, monitors excel. While close it's not the same.

At a close distance 1080p @ 32" is too large of a ppi. For monitor use, smaller pixels are preferable and yield sharper looking text. Thus a monitor is better. Backlight levels are also better and better controlled on a monitor, on a tv the brightness tends to be too high for close proximity viewing. A proper monitor also generally has better color depth.

Unrelated, just a possible problem. Something like excessive dust or bad caps could cause this.
