SOURCE: TV has frozen will not respond to remote control

You can try to leave in unplugged from power for 10 mins, then try again. But in all likelihood something as cold soldered on the inside you can either try to get warranty (if applicable) or get a new one.

SOURCE: My TV will not respond to the remote.

Hello
Do check the infrared emission from your LG remote control. Just to to this link, where you can see details about it. If infrared emission is there, and still TV does not accept it, the infrared sensor inside your TV is faulty and should be repaced. Ok

SOURCE: LG 47lg50 white screen no buttons responding

A white screen with nothing else leads me to believe you have a problem with a t-con board or a signal board on that TV.


you can get parts for this tv at www.interliquidparts.com

SOURCE: 52LG50 lcd tv has white screen will not respond to remote

You will need to take it to a qualified tech to have it diagnosed. Without looking at the set, it sounds like a T-Con board issue

Tip

TV shows either: black screen with: white vertical or, horizontal line


If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, find the too hot transistor or, chip; using component coolant; spray the too hot component with the component cooler until the screen comes back to normal. To fix: apply white coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.

Screen turn green tv is 57 rear projection


Good Day,
It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Good Luck, Big Irish.

Black and white


Your not getting color probably because of a weak "air" signal. The fix is a better antenna or an antenna booster.

Black boxes on a few TV channels - connected to DIRECTV


Turn off closed-captioning. You'll find it's set for "text" right now, probably from hitting a button on the remote without realizing it. The set is blanking the screen for the text which doesn't show up. (In your case sometimes it does. You're the first person who's ever seen anything that I've responded to!) On channels and programs where captioning isn't being sent the box doesn't show up, so you don't know you have the trouble.

Tv Has Big Black Box


shut off close caption. use the CC button onthe remote or go in to the menu and change close caption to CC1. this box is the close caption in TEXT(1,2) which will put on a black box whenever there is caption present.

'F' displaying on screen and remote not responding.


Excavated with Google from Philips website: " When a letter F appears on the right hand corner of the screen it means the television is in factory mode. To exit from factory mode, press the 'VOLUME -' and ?CHANNEL -? buttons on the TV set simultaneous for 5 seconds. " Hope this helps Michael Junge
