CRT

by the way, about my sony tv, big filter capacitor is good! i check smps primary winding with ring tester, 8 leds lit.

Noted.

pwr supply board is separate, when i switch on the pwr supply without load, 470ohm resistor burned besides the posistor, i change the resistor but same thing happen. is posistor have problem?

Did you connect the degauss cable?

smps x’former have regulator ic STR-S5941 but all voltage drop at all output diodes and i change already the regulator ic but still humming sound coming from the smps x’former.

Have you check all components and isolate the power supply?

when checking HOT onboard in crt monitor is the same also in checking on crt tv?

Yes it is the same. Try isolate the section first.

should no reading blk prod to collector(center pin) and red prod iether way?

Yes at x 1 ohm. If you are not sure you can remove it and retest it again.

i check primary of flyback x’former, 8bars lit!

Noted.

and when i check HOT onboard of crt tv, it has reading, but when i check HOT offboard, its good. can you give me a little advice for this jestine? thanks and god bless…

Try pull out the yoke coils cable and remove the flyback and see if the HOT still have reading or not when test on board. Sometimes a shorted secondary winding to primary winding in flyback could cause such problem
