390 ohms
« on: January 25, 2011, 08:17:26 PM »
mga master tAnong qlng kong ilang wats pwd q ipalit s 390 ohms resistor hnd ko alam kong ilang wats nbalatan n kac ung kaperaso lang nbasa ko 390 ohms nkalagay try q lagyan ng series 400 ohms prang habang tumatagal nasu2nog...

ano po kya mganda teknik pra malagyan ng tamang wats ung 390 ohms???

galing syang fbt papuntang yoke or >:( COLD po ata ung nkaprint s board nya??????

dapat same sa laki ang ipapalit mo sis
sure ka ba na 390 ohms yan?
baka 39 ohms lang?
mas ok sana kung post mo dito ang modelo ng unit mo at baka may schema ang mga master

hindi po xa square kakulay lng nya un. halos kacng sukat xa ng 1/2 resistor...nkalagay xa malapit s fbt hnd ko n po tanda kong ppuntang vertical section nsa work n kac q...basta nong my display n cnara qna xa kala q kac ok n tpos nong paAlis nq biglang dahan dahang dumilim uli hangang sounds  nlng natira sabi q ba2likan ko nlng...

tutukan mo ng tester yung mga voltages sa CRT board hangang sa mag Dim, measure mo ang Heater, Screen Voltages o G2, RGB volatges. sana makatulong

kahit isang bayong na carbon type resistor ang ilagay mo jan ay sure mangingitim pa
baka flame proof resistor ang orig nyan
FPR ang sagot sa tanong mo kapatid na TS

di kaya symptom lang yung umiinit na resistor?

something is causing it to heat up, find the cause of the problem

@TS,paki check mo kung may nakakabit na transistor dyan sa r-390 ohms @ baka yon ay may leak or may konting short na(out of circuit test)kung kaya't matapos maipower on eh nag-iinit na yang 390r @ magdrop na ang voltage.thanks and good luck....

update lng po my nabuksan akong tv d2 s work q ito ung model 21v-k80m ganito po pala ang model nya....

galing pala xa ng vertical papuntang yoke...hndi kulang nbasa value nya kac speaker lng ang cra kaya hind q ntangal s board ung resistor pra tingnan...

patambay para matutu naman ako..
@ ts hindi lahat ng umiinit yon ang sira kahit lagyan pa ng 2watt yan iinit parin,may ibang problema kaya umiinit ang resistor baka sa yoke.

baka normal lang na umiinit yan, check sa load ng resistor..bka my nag leak na..anu ba voltage na pumpasok sa resistor?
