up!

manga sis confused ako d2 sa value ng resistor 3517.

3517 = orange, orange, black, gold, violet. = 3 3 0 0.1 10 %

panu po ba coding nito?

33 ohms ba to?

open kac ito eh.

may nakita kc akong diagram sa thread na ito

http://www.electronicslab.ph/forum/index.php?topic=26054.0

15 ohms ang nakalagay na value ng resistor 3517.




3 3 0 0.1 10% = 330 +/- 10  ( lower value 297  higher value 363) = within acceptable value for this resistor. tama?

-ngek mali di ko nasama ang multiplier kasi sa iba wala ang gold as multiplier, yung iba 0.1 gold pag multiplier. pati ako nalito. mataas pa rin kahit -10 percent ang 33 ohms. most probably dapat sundin ang schematic unless may love notes from philips na design modifications. Meron nga ata itong design mods. ANUBIS - S mahalungkat ang baul.  ;D ;D

TS kung hindi sigurado sa Value at e tra-try mong lagyan mas unahin mo sa mataas ang value pababa. para safe..pero yung approach na ganito is depend sa circuit not always..sana makatulong
Gawin mo ang nais mo, sundin mo ang gusto mo dahil ikaw o ang sarili mo ang hari ng yung kagustuhan...

yung 7805 mo ba good? ito madalas palitan diyan pati yung 8 v regulator dapat may heatsink na ito kung abot na sa design modification yan bago lumabas.  ;D ;D ;D

Manga sis update ko lang.

ngayon ko lang naikabit yung resistor.

OK na ang tv, may power na. 33ohms ang inilagay ko.

may nakita ako sakto ang diagram. kapirasong picture nga lang.



salamat ng marami.
gamitan mo ng microscope.

sensya na sis mcleod yung heatsink ay parang bakod sa gilid ng board at nakashare sa lahat ng power components maliban sa audio ic.

pede mo i-check yung 8V (L78M08CV) regulator. tingnan mo pin out ng IC 7225(section E) tama supply nito.
