san po makikita yung 5volts
Quote from: mcleod on May 19, 2012, 03:39:24 PM
1. eto yung last time di ba. 30 v sa 400 v na primary ecap?

2. ano yung nagshort na transistor? saan nakalagay malapit ito ba yung near sa horizontal drive transformer?

3. ano ang main regulator nito?(str XXXX)? or transistor din?


 4. yung mga 2 watts resistors near sa bridge diode, na-check na? yung bridge diode, good ba?

5. 5 volts regulator mo for standby, good ba?

ok nman bridge diode at power resistor, may click nman yung relay,

kapag may tik ang relay check mo kung nakarating ang supply sa primary filter cap. dapat meron at least 300vdc. Pero parang na mentioned mo na mababa nga nasukat mo di ba? So un ang alamin mo. Ilang pyesa nlng ang involved dyan.
