When tv is powered on tv only displaying channel number and sound -no raster. using video mode displays are ok. sound is also ok


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

How to fix 14v-s100 sharp crt tv no raster only channel and volume display on screen


If there is no video signal input, this kind of fault can occur. An abnormal "Screen" voltage too can be the cause. If video processor IC or the tuner is faulty, this kind of fault can occur too. You should check all this. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

2) test the power supply , check the horizontal output +125vdc ,vertical output from +80vdc, +al other circuit +12vdc, if there are missing fix it, see the diagram attached.
3) TEST the signal from tuner,i-f, detector, AGC

Television will not come on. Have power but no picture


You did not say if you have raster on the picture tube when TV is turned on. If yes, to confirm any problem with the TV tuner section, connect a DVD player, VCR or A/V output of another TV to the A/V input of your defective TV. If you get picture, problem is with the TV tuner.
