Re: Help...can transistor NTE2653 replace with 2SA608N/2SC536N
Yes the old one transistor i I've replaced is problem, there's short circuit between all pin, multimeter reads zero ohm for all combinations test.
Yes tom66 this PSU make for Toshiba TV, it has no BN44 serial no, you can search using this no PSIV231i01T. -

Re: Help...can transistor NTE2653 replace with 2SA608N/2SC536N
Hello all, finally i replaced the transistor NTE2653 with 2SD1347, but the problem still cant solve,....Actually this part use in power supply section, and this lcd tv model is Toshiba 40av700e,......the problem is when I switch on the tv it will show display and sound for about 2-3 minutes and then blank without sound but stanby led still light. I testing psu board, their stanby 5v present but no voltage for 13v pin. Here's how i test this psu, disconnect this psu board from Tcon board, LVDS and backlight. this 2 pin(5v...Leave a comment:

Re: acer v193w no power need help
Hi, budm, yes its through hole IC with 3 pin leg. I have measure all pin with analog mmeter and results is.
black probe....................red probe....................result
1......................................2........................16K ohm
1......................................3..........................8K ohm

Re: acer v193w no power need help
Hi all, i have acer v193w lcd monitor, but the problem now is no power. The output voltage from the power supply board can`t get real voltage it should be. The 14V rails i get only 9.3V, 5V rails only 2.6V. To confirm if the power supply or the mainboard have problem, I used 24V light bulb in the 14V output line, an ON the power, no light appear, that means power supply itself have problem. I have replaced all electrolytic caps except big caps 100uf 450v coz no stock. But i expect the big caps 100uf 450V is ok. Below i attach picture of power supply...Last edited by rizzz; 04-26-2013, 05:45 PM.Leave a comment:
