Hitachi 27" tv set dead...and close to being filled with sand...
Hello all,
I have another nice piece of equipment that is very close to the trash... but i'd like to fix it just for not having to send it to the dump ( ahhh the real reason is that it is so heavy that i'll be easyer to fix it and put it back and move the new one then to take it to the dump ;-))). (I already bought a new one to replace it...had pressure from the wife...) Well here it is: Hitachi model 27AX3BC chassis no M1CLXU serial 04569 made in 95 ( only 9 years old...) some time ago it started to scroll, (but there is no longer a vertical scroll adjustment like in the old days!, but i'm sure that would not have corrected the problem anyway) Then in a matter of days the vertical just stop and the long white line appeard...then the fuse blew! I oppened the set but there is no apparent dammadge: no burned transistor, no resistors burned or damaged caps. Humm, i have no schematic and there are quite a few chips in there. I suppose i have to replace a chip, some R and a couple of C but witch ones? help! |
