hello peeps. pahingi po ng tulong. recently, we have a newly acquired car, syempre new ang battery. Now, i got an LCD and i want to play ps3 on it. So i bought this power inverter sa ACE builders, IFONIX 200 watts 220-240 volts daw.

nung isaksak ko sya sa 12v via cigarette lighter plug, lumabas sa screen kaya lang maalon. So i though, wattage ang problema.. then i got this 600 watts naman na power inverter kapalit nung 200watts. Since mataas na ang wattage, ang supplied cable is the one with the clamps so direcho sa battery. I just tested it kanina, ayaw pa din, again, parang umaalon na tubig yung screen.

Ano kaya ang ibig sabihin nito? hindi ba kaya ng inverter? eh mataas na wattage na yun ah. Kasi... nung isaksak ko yung PS3 sa 220volts AC via an extension in our garage, ayun gumana sya. malinaw at walang alon. With the inverters ayaw gumana ng maayos.

Can anybody with knowledge in car electronics please help me? before i bring the inverter back for a refund

thank you
