I have a 37LG505H-UB LG LCD TV and when I watch it, it all of a sudden starts scanning for channels on the RF input even though I have it hooked to HDMI on the STB. It won't stop and when I turn it of


Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

have Aiwa TV MODEL No. TV-A209
The problem that I am suddenly facing is that I can't change channels or volume or use any other function. I can't even turn it off with remote control.

Its stuck randomly on a particular channel that I was watching at that point of time.

Along with that channel it now shows a message in flashing red color that reads :-
AGING
O6895H

Now when I press ''Display'' button on remote control volume goes off and this code is shown :-
S123 K234 Y
000 001 1


The numbers in the second line can be navigated by ''CH+'' button and changed between 0 and 1 by ''Vol+'' button.

I really don't know anything about this. So, please help me out of this problem.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Status light just flashes red and will not turn on


Firstly, unplug your tv for at least 4 hours. Over night is better. This is what we call a Hard or Master Reset.
This should solve your problem. If by chance it doesn't, then more than likely your power supply board is shot.
Very common in the newer tv's

Channels change by themselves after 20-30 minutes of tv being on


Have you tried covering the IR eye on the front of the TV when this starts occuring? Sometimes other devices in your home can emit infrared light that in rare cases can be picked up by your TV as a command from the remote. If covering the eye seems to stop the problem, I would say my guess is correct. If the problem continues even with the IR eye blocked I would say that the internal tuner of the TV might be defective. good luck!

Power button Flashes


For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
Thanks,
Dan
