As i can not see the circuit or the schematic diagram... as you have said..there had no 5 volts, please check the IC regulator coded: 7805.

Click here to download the user manual to your TV. It has all details.

where is the reset button on my sharp 19" tv it,s my front tv located on my rv.

please change capecitor in SMPS powersuplly

Focus adjust is located on the neck board or on the Flyback transformer, another fault is dirty spark gap inside the CRT socket

there is a lot of posibility you should contact one authorized service to fix that problem you cant do that yourself .
There is a big consumption and the power surce go in protection mode

this could be a memory error.please,contact the nearest repair shop.do not turn it on again until then,please.

Good day.
Try to check the crt socket. Also, check for the loose contacts along the Chroma IC. Like wise, there is a screen adjustment on the rear portion of the flyback. Try to adjust the screen.

Response is highly appreciated.

The Sharp 25R-S100 TV is a standard NTSC TV with a 181-channel PLL tuning system....which means that it is not digital.
