Sziasztok!
Ennek akészüléknek nem működik az invertere.
Kipukkant a trafókat meghajtó fet /Q10/poziciószámú.
Nincs róla doksi és nem is találtam, de ez egy 4 fetet magában foglaló 8 lábú smd ic.
Ha rajzot, fet tipust, vagy esetleg valami hasonló 4-es fet tipust tudtok,
előre is köszönöm : Laci
Sziasztok!
Tudja netán valaki???
Semmi rajzot nem lelek, ketté van törve az említett ellenállás, valami ráfolyt :(
Panel is elég ramaty de muszáj meglennie, több darab is van hasonló gép, mind meg kell ma csinálnom.
Köszi!
Üdv:
Pityesz
Hi,
I'm sorry for writing in English, but I don't understand any single word in Hungarian and I couldn't find an English subforum there.
I have changed the LVDS controller and now it's working perfectly, but I need help with the backlight. The CCFL lamps in the screen are OK. I connected the screen to another inverter (from BenQ T705, made on TL1451 which also has "protect" function) and the backlight worked perfectly. Again, I connected other screen to the malfunctioning ILPI-075 inverter and the screen also goes blank.
I changed all THT electrolytic capacitors on the board, but not much has changed. Before, the backlight was turning off almost immediately, now it glows for 1-2 seconds and then turns off.
The HV side of inverter transformers is about 470 ohm, they look OK.
I measured random capacitor in the +16V line, which is supplying the high voltage inverters.
We can see how the voltage went down while the backlight was powered on.
Also, the ON/OFF signal on ICL837's pin 8 is always present after powering up the power supply, even after the backlight turns off.
I don't have any idea what to check now..

This elderly monster arrived with the error “ 4 blinks “ which the manual suggest is a power board fault There are TWO power boards and a standby power board inside.
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained.
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ].
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out, I have done cold checks on both boards and there are no obvious differences.
The manual has only a block diagram of the power supply so it’s difficult to be sure of values / voltages.
My question is has anybody seen or worked one of these or similar beasts
Many thanks Ken
