LG 37LD450 37 in. TV - Answered Questions & Fixed issues

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

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.

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.

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.

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 .
ok

You need to inspect the power supply module for bad caps with domed tops, that is more likely to be the cause of your problem.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors pictures: http://s807.photobucket.com/albums/yy352/budm Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps. Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

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.

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!

Please check the link below and try if the codes work.

1. Using your Remote, press the Menu button, and select the Picture icon.
2. Find the Picture Wizard, and proceed through the steps.
3. Also, try and adjust the aspect ratio to see if this helps.

warnerallens - Have you been able to fix this problem? I am having the same issue. Thanks

Look for bulging caps.

Find a good 720p station and work from that. Don't try and make an analog station look good because with the new sets they just look terrible compared to a hd station. Your set will show you what it can do.

Does other functions work, if it does, the more likely to have worn out carbon pad on the power button.
Testing remote control: The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Capacitor kits: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Please post back what you find.

try swiching it all off then turn it back on to see what that does if still nothing it sounds the power mod is gone my advice to you then would to buy a new tv as the brand you have are two dear to fix.

Clean the Lens: Use a DVD cleaning disc to clean the lens. If the problem persists, consider professional cleaning. Test Other Discs: Try playing different DVDs to see if the issue occurs consistently. If it's specific to one disc, that disc might be the problem. Check for Updates: Make sure your DVD player's firmware is updated. Refer to the manufacturer's instructions for firmware updates. Try a Different TV: Connect your DVD player to a different TV to see if the noise disappears. If it does, the issue might be with your TV. The hum is simply the player trying to read the disc. It can't so, it spits it out. Remember that prolonged use of a malfunctioning DVD player could potentially cause damage. If the problem persists, consider seeking professional repair or replacement

Question edited for clarity. It appears to be an LG rather an an IG. https://www.avforums.com/threads/lg-42lb1db-how-cani-remove-the-swivel-base.519459/ Further Help and videos https://www.google.com/search?q=lg+42lb5df+remove+base+stand ..

The screen blank out

Likely a dry connection where the HDMI socket it soldered to the board. https://www.google.com/search?q=LG+PLASMA+TV+MODEL+NO.60PS60-UA+that+is+not+picking+up+the+HDMI Old plasma technology though, time for a new one, as quality has moved on. https://reviewed.usatoday.com/televisions/content/lg-60ps60-plasma-hdtv-first-impressions-review-830 ..
