My REsz21rd is doing the same thing, switching off after a short time and then struggling to re-start. The LG repairers say it's the projection engine and have quoted £2000 for a new one. What a joke!

Hello. I got a Lg tv which i brought 3 years ago. After putting it on standby usually the red light falshes 3 times until it turns blue and comes on. since last week the red botton just flashes...


First disconnect all power to the TV for about 30 minutes this gives the filter caps time to discharge as this resets the logic section upon power-up. After 30 min try powering back up if you still have the same problem then there's a problem with the power supply board. You may have some caps with high ESR levels which can cause this kind of fault. But it could other components on the power board causing a similar fault like switching transformers that have shorted, or opened either which can cause EDDY Currents which will cause feedback in opto-couplers and shut the TV down. Let me know what results you get after the 30 minute power-down.

This procedure is for LG CT810.

To RESET your phone back to factory defaults which will erase all current content and revert the device back to original shipped configuration:

1. Turn off your phone,
2. Remove the back panel and take out the battery for about 30 seconds,
3. Put the battery back into the device and replace back panel,
4. YOU MUST PRESS AND HOLD THE FOLLOWING BUTTONS SIMULTANEOUSLY!
a. Left Volume Down Button, AND
b.Right Camera Button, AND Power Button
5.Hold them until you see the green Windows Mobile startup screen and then you can let go,
6. After a few moments, you should see the initial screen caliberation screen,
7.Your device is now RESET/RESTORED to Factory Default (this assumes you have not applied a custom ROM, in which case the reset will simply go back to the defaults of that package)

When i open the gallery, phone shuts down


what has happend is that the phone has detected a virus, like if you have ever used the wire that came in the box to connect to your computer to charge or to create mass storage and the computer has an undetected virus that can get into the phone via the wire, so what i recomend you do is that you scan your computer for undetected viruses, and also restore factory settings on your phone turn it of for 30 seconds turn it on and try again, if this does not work contact your service provider or LG themselves and treat the situation from there.

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

HI,

All I can suggest is to replace the bulb. I experienced a similar problem after about 2 years viewing when the recommend lamp life was approx 8000 hours (I got to approx 3000 hours). There is a service menu you can access where you can reset the lamp hours time. I have read that if this is reached you must replace your lamp, but you can extended this by reseting the hours.

I have since learnt that a lamp bulb can go at anytime, so it is worth having a spare. Also I have noticed that switching the TV off at the switch (not leaving it in standby helps).

Try this to access the service menu. Holding down the menu button on the remote and the one on the TV for a few seconds. I think the TV needs to be off.

From memory, I think it is option 4 and option 5, then reset the lamp hours to zero
