You have replaced your lamp and the set is working fine but the 'replace lamp light' is still on. What do you do?
This is an important procedure because you need to know when it is time to replace the lamp again. If you do not reset the timer you may run the risk of having the lamp explode, because it was not replaced in time. This can be dangerous and could cause a fire. At the very least it will cost you more to repair.
The manufacturers goal for having a lamp timer is to get the customer to change the lamp prior to a catastrophic event happening. Most lamps only last for about 3 years and that equates to 6000 to 8000 hours when watched for more than 8 hours per day.
To reset first make sure the TV is unplugged from the electrical outlet.
1) Turn the main power switch to the "ON" position.
2) Press and hold the "On/Standby", "Menu" and "Input" buttons at the same time. The buttons are on the projection TV. Though the same buttons are found on the remote control, the reset only works with the buttons on the TV.
3) Plug the power cord back into the outlet while holding the buttons in Step 2.
4) The lamp timer will reset when the projector receives power.
This should reset your counter and you will be ready to enjoy your TV for about another 8000 hours or three years which ever comes first.
Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.
go to menu and see if you have a timer off or timer on to turn the tv on automatically. I have a 24" RCA TV and i have a red light that stays on after i turn it off this is normal. make sure you are not recording if any.
I would believe that you don't have the sleep timer set to a 5 minute period?
If it's a few years old then the problem could possibly be in the power supply. When a component finally heat's up, then the supply goes into protect mode and turns the set off. There are good servicer's out there that should be able to fix this. LG is really Zenith 'US' and Goldstar 'Korean'. They combined forces a couple of years ago. Zenith was well known for cracked soldering joints. This also could be the issue. Blessings, A/V Media Guy.
Power/standby must be off. Press and hold "Timer/CLK" for 2 seconds. Use the up/down buttons just to the left of the Timer/CLK button to select 24-hr or 12-hr mode, then cycle through hours, minutes. In each case u can use the up/down buttons to set the time.
