LG TV 21"NORMAL PCB
MAIN IC TDA12135PS/N3/3/MB5
EHT 6174V-6006N
VERTICAL IC LA78141
SOUND IC TDA7297SA
AV IC LA7958N
STR W6554A
H OUT BLOWS OFF
1.Measure H OUT transistor-----Short.
2.Open transistor.
3.Again measure transistor-------short.
4.Power on----measure EHT supply voltage-----high.
5.Power off-----Add 100W lamp at EHT supply voltage.
6.Power on----measure voltage-----OK
7.Open capacitor C471(682/1600V)------reading-----internally open.
8.Set new transistor MD2103.
9.Set new capacitor 682/ 1600V
10.Then-------

[@CosmicElectronics]

1.Check resister 91k ohm(two pieces)
2.Check KIA431(original).
3.Replace opto-cupler.
4.Check 5.6K ohm resistor
