VERTICAL IC LA7840
SOUND IC TDA2006
STANDBY RELEASE
BUT NO EHT
1,Power on/Check eht supply voltage----ok.
2.Check H OUT collector voltage----ok.
3.Check horizontal driver transistor voltage----ok.
4.Check 5V regulator input and output voltage-----ok,
5,Check 8V regulator output voltage----ok.
6.Check 3.3V regulator voltage---ok.
7.Check memory ic voltage----ok.
8.Check 8V,main ic pin No.14----ok.
9.Check voltage main ic pin No33(H OUT)-----missing.
10.Tracing voltage source.
11.Register (R524--3K) input 8V supply present but output supply missing.
12.Register maybe defective.
13.Power off/Check registerR524(3K)---high registivity.
14.Open the register R524--3K
15.Again measure old register----high registivity.
16 Set new register.
17.Then discussion the fault by circuit diagram.
18.Then----
