Check Vertical IC out (LA78..) and resistor voltage supply from flyback transformer to this ic. Check the STR main power supply(and resistor near, change value), some times seems good out main board,but in operation not good

You're discussing about the width problem to picture. If yoke have a short in between its wingdings [even a single winding short], will cause the failure of horizontal output transistor. As per you report here, the set has a raster, but problem is with the picture width. There possibliliites for this fault are. 1. Lack of voltage from the SMPS power supply output. 2. Horizontal width capacitor. 3. Horizontal output capacitor. Check the output voltage from the SMPS section first, and confirm that it is OK.
it sounds that have problem in the chroma board ( video board ) a small board that hooked up in the neck of the picture tube. if the color is greenish the cause is dead in red video driver transistor or open resistance. hope this can help good luck.
Sorry,u must have it orignal codes,there noway to unlock secrect personal codes.U push the channels + or - buttons manual controls couples times.Might get in the tv input.Hook up,use it with DVD player can watch DVD Disc thought.Sorry, you probally only can watch shows rated Y for children only.
the main chip in the TV that controls all these options (sound - sharpness etc...) you will need to bring this TV into a repair shop - the transformer that blew up caused a voltage surge that fried this chip
The solder joints on the degaussing thermistor have cracked or the thermistor itself has opened, and the CRT is heavily gaussed. You can degauss (demagnetize) the picture tube and the colors should return to normal, but the thermister should be resoldered or replaced.
