Re: pioneer XV-EV7 timer blinking only
kumpleto ba ang supply mo sa PSU sis? kahit naka jumper na ang relay... mukhang may tama ang front panel board kung sakali man dinisable mo na ang main amp ic or ckt

saksak mo ulit sa AC and wait for at least 3 min
tapos press power
tingnan muna natin kung mag popower

Ayan si Sir Danny.. mas gamay niya yan...
suggestion ko naman na e try mong resolder/reheat ang spider ic sa front panel.

Re: pioneer XV-EV7 timer blinking only
duda ako sa mcu mo sis... na try mo naman siguro e resolder ang mga knife connector from amp board to front panel at mpeg board.. pwede nga yan sa amp board kung may power error senses sana... pero tinitignan ko ang mapa ng EV700 ay for AMP preamp standby lang....
maybe may probs pa yan sa unahan... o output side ng amp...
try mo nga float lahat ng amp ic. pag walang pinagbago balik mo nlng ulit...
