Defective Dell LCD monitor (share ko lang)

Post by ultrasonic™ on Wed May 15, 2013 5:26 pm

eto share ko na rin even super duper na basic,,,
may pumasok ding LCD monitor sa bahay nung sunday

DELL E156FPb model



trouble: No power, Dead set.. walang ilaw ang LED indicator

culprit/salarin: tiyak bulky caps na naman eto (^_^

para makasiguro buksan nga natin (^_^


needed lng naman nating eprepare ang mga sumusunod:

1. Prying tools



or any plastic metal na parang kutselyo.. purpose nyan ay para pangbukas at pang iwas gasgas at deform sa plastic case ng LCD monitor.. pero kng di nmn masxadong strict ang tumer pwde na khit metallized like kutselyo & etc.. (^_^

2. Screw drivers pang tanggal ng mga metal screws



3. Soldering Iron, Solder lead, & Desolder Pump



4. Electrolytic Caps (mostly 1000uf/16V-25V, 680uf/16V-25V at 470uf/35V)



pag prepared na ang apat sa itaas ay pwde ng simulan ang pag repair

itaob ang monitor sa table..



then visual check for some screws na nasa labas lng..



pg my nkita.. kunin ang screw drivers at e unscrews lhat ng screws..

pag ok na.. or sbhin nating natanggal na lhat or wla tlgang screws nkita..

kunin nyu na ngyon ang Prying tools nyu..
eto ang isa sa pinaka important part.. wag lng kayo tusok ng tusok without knowing kng saan kau tutusok (^_^

look for Hole opener spot...



at doon itusok ang prying tools..
mapapansin nyu yan agad dahil parang my Gap na kasya lng ang ulo ng Flat screw driver (^_^

then dahan dahan kalasin ang Front Casing sa Main Casing





hanggang sa mapaghiwalay



Note: sa puntong to... dalawang klase ang alam ko...
defende kasi sa model ng LCD monitor na bubuksan nyu
1. my nkabuild up pa sa metal casing at 2. ung Direct na sa LCD panel ang Plastic Case

xa model nato ay my metal case pa...



so balik ulit sa basic.. look for screws & wires na makakaharang sa pagbaklas... gaya nlng ng wire ng CCFL socket/plug

pag ntanggal na lahat lahat ng sagabal at Cguradong ok na ay..

ihiga nyu na ngayon ang LCD monitor na nakaharap sa inyo ang viewing pint (^_^



dahan dahan nyu na ngayon e-angat ang LCD Panel sa casing nya..



ingat rin sapagkat nkakabit pa ang LVDS cable..

so remove it safely



at esecure ang LCD panel sa ligtas na lugar para di mabasag..

bali ganito nlng ang maiiwan (^_^



sa wakas.. nangangalahati na tayo (^_^
balik na nmn sa basic.. visual check ulit to look for metal screws & wires... loosen them & remove.. specially ang IP board... yan nmn tlga ang objective natin para masilip ang mga Filter Ecaps..



Trivia: IP = inverter Power board yan.. pnagsama ang Inverter Circuit at Power supply section / SMPS

Ok taob na natin ang ating pinaghihinalaan (^_^

abra ka dabra.. boom..



mga buntis nga ang mga Ecaps (^_^



so remove nyu ang mga bulky caps para mapalitan ng bago with the help of soldering iron & desoldering pump



note: SOP rin na palitan ang mga Ecaps na di pa bulky.... para iwas BJ (backjob sa susunod na buwan) (^_^

solder nyu na ang mga bagong palit na caps





pagkatapoz, ibalik ang mga wires, boards, connector at metal screws para matesting nyu na sa working System unit/CPU

pag nagkadisplay at ok ang image
ay ibalik nyu na sa orihinal na hitsura

Note: para sa good practice repair.. always tandaan kong ano ang huli nyung tinanggal ay iyong din ang una nyu ibabalik. at iyong unang nyung tinanggal kanina ay iyon din ang huli nyu maibabalik...



so babad nyu ang unit... kng nasa condition nga



at kng ok na nga.... ay ready to release...
hahahahaha

congratz sa tumer naayos ang monitor nya (^_^


next on the line nmn etong Redfox Led Monitor



xa nga pala my mga images sa itaas na di tugma
hiram ko lng ky kuya google
lol!

Master Ultra magandang hapon po at sa ibang mga master. Mga master ask ko lang po sana kung pano matanggal ung password sa cmos set up. Nakabili po kc ako ng laptop acer aspire dual core ndi ko po ma reformat kc may password ung cmos set up. Maraming salamat mga master.
