Raj asked:
Hi, I have a Sansui 15″ color TV Model: CTVB2B15-P. It automatically switched off. When checked, fuse was blown out, I tried replacing the fuse, but it again blown out, so suspecting the problem with SMPS, I further checked and found that C4460 transistor (or STR) was short and replaced it, and now the fuse doesn’t blow off, but still TV is not powering on,I’m not sure what else could be the problem, I get around 30 volts only at base terminal of C4460. Please help, I don’t have schematic/circuit diagram of this TV. Thanks in advance, Raj.
Check for shorts on the rectifiers and supply lines out of the power supply.
Then REBUILD the regulator circuit piece by piece…
