In-circuit LOPT/FBT Tester kung sino interested magpagawa nito. I made this tester since 2009 functional, kung sino lang ang interested kasi mas madali lang pag trouble sa TV, Here’s the design for a low cost, easy to build and use battery operated ‘shorted turns’ tester for
line-output or ‘flyback’ transformers, and other HF wound components like deflection yoke windings
and SMPS transformers. Tests have shown it capable of finding at least 80% of LOPT/FBT
faults, so it can save a lot of time and trouble. Small and rugged, it’s well worth a place in the toolkit
of anyone involved in servicing TV receivers, video monitors and computer power supplies. yun ang magawa sa LOPT/FBT tester. Tatanggap ako nang order.

nagawa ko na eto a year ago...yang version ni bob...yung version ni AnaTek (blue) may nag-share na niyan ng files sa tv repair section. Yung ginawa ko pinamigay ko sa tech friend ko nung tumigil na ako sa shop, siya na lang nagkumpleto ng kaha at ayon sa kanya working good naman daw...

sori TS, I do not mean to interrupt...pls. do not be offended

stelling5 · « **Reply #13 on:** March 15, 2012, 02:58:19 PM »

kasi friend mo yun, yung hindi mo friend binigyan mo rin, post mo yung blue LOPT/FBT para may copy naman ang mga user dito. pag mayroon ka

abeTIR · « **Reply #14 on:** March 15, 2012, 03:16:17 PM »

^yung friend ko kase sis, ay isa sa mga unfortunate taga-probinsiya siya he does not have the resources to build one, and he was a humble and a good tech. Hanapin ko muna yung mga files ko baka nai-save ko pa sa ibang USB...

Yung blue files, kung hindi ako nagkakamali si AC/DC ang nag-share nun...

AC/DC sis where..were you...need your kindness here..

I thought you will share in this thread the schematic, PCB layout etc. but rather you are offering it for a cost which is not a problem
but like What Kasamiko said please post in proper Thread.

Now if you could provide more detail on how the gadget works specially for newbie eh baka magkainterest pa sila bumili nito....

just my 2 cent. Ok PRESSING REPORT TO MODERATOR

@Mod / Admin.... kindly move to proper thread. Many Thanks.

RaffT · « **Reply #16 on:** March 15, 2012, 03:23:04 PM »

cge paki share kasi mayroon dito hingi nang PCB design, Schematic diagram, and component list and replacement of component. thank din ha... kasi dami hanap nag blue FBT circuits

stelling5 · « **Reply #19 on:** March 15, 2012, 03:29:10 PM »

yung functional ha baka sabisabi lang wla namang nakagawa dito, lahat sabi nakagawa, post nyo para makapag gawa naman ang hindi pa nakagawa nang LOPT/FBT at saka yung bago ngayon, resistor and capacitor, diode and transistor tester, baka mayroon kayo dyan nagawa para ma share naman natin sa lahat na user dito.
