LG CRT TV, picture becomes yellowish

I own LG CRT TV, model is 21FB5RLX-ZV. After I turn it on picture is OK for a few seconds but then it becomes yellowish. Also sometimes while TV is on colors become normal for some time so I suspect bad solder somewhere.

    I already tried to resolder whole board attached to tube but problem remains. There is only one chip there TDA6107AJF/N1. Now I didn't suck away old solder and put new but only heated solder joints until melting point, could that be problem?

    Tried resoldering it with new solder, now when I turn TV on colors are OK but now after a few seconds screens first becomes redish then greenish and in the end yellowish and it all happens within few seconds. Is it possible that the chip is damaged?

Check its solder terminal at the CRT board [Filament voltage]. It sounds like the filament do not glow after some time due to a loose contact at the CRT base connector sockets. Check it.

If this does not help, check the ABL circuit for any open resistor.

It can be a result of dry solder joints on the CRT base PCB, the PCB you see on the end of the CRT. Resolder all the joints on that board perfectly and thouroughly and this will be alright. Good luck.

Power light blinks and no picture


No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.
