Tv turn on,this happen.Make a fist bang on the tv frame,see if tv have a picture come back or have it flashes in and out?Yes,than tv is having cold soldering joints on the video board pins that connections to between video board and the CRT-(tv tube) those joints connections pins on the video board are to make the CRT-(tv tube) to have a picture.U have all the tools like a soldering iron,a roll of solder and also can u do basic soldering work?Yes,take the tv aparts.The video board,that the the board that connected to the CRT-(tv tube).Resodering all the soldering joints connections pins between CRT-(tv tube) and video board should solved this problems.Or tvs shops can do those resoldering for u,by telling them the problems.It should cost u like around $50.
If the fuse is intact in all probability the power supply unit is OK. If your Horizontal Output Transistor fails you will hear a high pitch whistling sound . Any way its the black three legged device mounted on an aluminum heat sink near a transformer from which a Red wire goes to the top of the picture tube.
Check resistors in the small PCB connected to picture tube. Check picture tube grid voltages. Check brightness control swing on the IC out put. Note down the IC no and search in the Google for pin configuration.
Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.
It sounds like the audio cable from the DVD drive may be loose or damaged. Did you wall mount the TV and this is when the problem started or has it always been like this? If its under warranty, contact the helpline on 0871 2000 463, be warned, if its becuase the cable is damaged by a wall mounting screw, its clearly evident and they will charge for repair.
The most common problem would be a bad solder joint on the vertical drive IC. It could also be a bad solder joint on the flyback transformer, as it supplies voltage to the vert. stages. If you disassemble the set, please be careful not to get shocked. Discharge the high voltage stages as a precaution.
