LG 37LD450 37 in. TV Questions & Answers
Why does it overheat?
does it overheat and closes or just superheats but works fine
from Lcd to lcd the lcd temp is high cause of the ccfl lamps that bright the panel enough so you can see the picture
If your tv set was led the temp would be greatly lower
Remote control doesn't work
Have the remote itself first checked---most tv shops have a tester--point remote at it and press buttons and it reacts-----Many digital cameras will react on their display screen in a very dark room in the same way.If remote itself tests good the set has a receiver that takes the signal from the remote and it may be bad.
Need manual in English for LG 37LD
Hello
I've the user manual of your TV in my system. I don't remember from where have I donloaded it and when. It is in Adobe pdf format. If you wants one copy of it, send your email address to me by FixYa comment box, and I'll send it to you by return mail. OK.
I downloaded videos in usb
hi,
Try one thing. Next time before copying the file to usb, format it. After that copy file and then connect to the TV.
ok

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.
The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.
Have just bought an LG37LD450. Buzzing noise
Had this problem as well. Ran through a laundry list of possible solutions. Finally found that the key is to increase the backlight (Access via [Menu] [Picture] ) to 100% and the noise goes away. If this is bad for the life of the backlight, just pray the backlight burns out inside year 1 while the warranty is still valid!

hi,
You have to check the back light of your lcd TV. All lcd screen
have a back light to illuminate the pixels. you can conform is the back
light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.
first of all check all the electrolytic capacitors in the power supply
and back light inverter board.If available then replace these capacitors
first.
You have to check the back light inverter board. Normally
in lcd monitors you can see three circuit boards. power supply, mother
board, and the inverter board. If available then try to replace
the inverter board. There are high voltage transformers in this board.
There is a chance for its winding get short. You will not get the
transformer in open market. Try for the inverter board .

My LG LCD TV
Is it going one way - channel 1-2-3-4-5 bottom to up or any way at random. Find out which way and check the channel button on the TV to see if it is stuck.
