Re: Replacement of LOPT on an LG TV
You will have to cut solder /splice the 3 wires Be sure to dress the splices after soldering with electrical tape. That's the only way if the CRT socket is sealed. Just don't mix up your wires, They should be color coded. Let me know if you need any additional help.

Thats an optical grade coolant specificially made for CRT projection Tubes to keep them cool. You can get replacement CRT coolant from www.tvrepairworld.com each CRT will require one bottle of CRT Coolant.
Try to claen the top of three crt guns inside you tv. also the reflecting mirror behind the screen.
one more thing you have to check, that is the CRT base sockets. After some years of use its contact will become bad. As there is three crt guns there will be three crt base sockets on the neck of each. Replace all the three crt base sockets at the same time. It will improve picture quality.
You tv is a crt one , that means there will be three crt guns inside your tv. Check the base socket of all the three crt guns. if the base socket have some problem the picture will become out of focus.
That why there is two images. Just change the three base sockets of crt guns, will solve your problem.
its not bulb, its crt guns. before replacing the guns do one thing. replace the three crt base socket for the three guns (at ones). a white socket to which crt's neck connected. i think u will get a good picture
the problem is that the lopt is loosing power this can be due to a leak. in it there fore you will hear a hissing sound or the lopt is simply past its time. and will need to be replaced ( the lopt is a unit that sends power to the screen or in this case the globes the less the power the duller the picture)
