Breakdown of dark screen of Kang Jia LED32F2200C, this him breakdown encounters much stage, foster cordial relations between states without.
But I am in long trouble spot is located probably in having a process, because judgement majority is COF short circuit,encountered examination of a few carelessly to be not repaired afterwards afterwards, appeal on this breakdown net much still, do not have a result. Close paragraph time noes hurry, then the machine of fetch sought trouble site seriously yesterday, phenomenon of this machine error carries brightness on the back to present dark screen breakdown, audio judges logic board breakdown commonly or screen is bad.
This machine does not have logic board, examination screen side gate discovers 12V is normal, 3.3V, 1.8V is normal, VGH, VON, VGL, VDD switchs on the mobile phone to disappear next for an instant only. The experience that has embellished so with me judges screen COF to have short circuit, as a result of this type nevertheless this is planted breakdown is too much, I still want to find out breakdown to nod. Have in the hand fortunately piece identical sodden screen, this sodden screen flies to what celestial being does not have repair so, consult then.
The result discovers VGL nods red pen of black pen ground connection to receive block changing a spot to be worth hundreds of Europe, normal infinity, resistor of VON positive and negative is hundreds of Europe, black pen of normal red pen ground connection is received changing a spot is about the same infinity. Suspect these two groups of voltage have short circuit appearance then. Discover VGL and VON after many the examination finally between unexpectedly positive and negative is 15 Europe left and right sides, it is normal to mix more complete and incorrect. Afterwards I remove 3 after the dot disconnects ability in the picture short circuit, reopen machine VGL-8v, VON25V, of course VDD15v more this, because in front it produces tension.
The magnifier after passing discovers the macula in the picture, not bad these two the dot has VGL only, VON circuitry, clear carefully then char dot, disconnect for safe decision nevertheless these two lines, flying line is solved, the television after flying line gives a person, nevertheless above line of horizontal stroke having a root, this is original some or I fly to what the line produces to waited for an user to knew, so I fly line never this kind of phenomenon appears. Faulty feeling finds machine rehabilitate to this engine trouble nods me or do not have frustrated, won't take too much roundabout way next time.
