Back to : ikr blinging led .txt | Home

symptom:No picture. OSD and sound OK. LED blinks 5 times.

solution:
The problem from led flashing or by service(osd works fine) menu seems
to be the ikr circuit,but if everything looks fine from all DC voltages
on the CRT and the suplly voltages of RGB amlifier chip TDA6108jf=IC7001
then the problem is from the ABL circuit.

Check components C5112=4.7ìF/50V
D5007=PDZ6.8B-115(6V8 zener)
D5005=MMDL114T1(schotky diode)
R5122=47k/0.1w
R5065=220Ù/0.1w

If any of these components is leaky or resistors open,replace them all and replace also ASIC
ic0001=TDA9394h/N1/5/1031

good luck!
