Pentranic 1132 (CH-288) No Picture & Chirping - [FIXED!!!!!!]
gokun:
Thanks for the heads up Bad Man...one of them was, indeed, fried...decided to replace both just to be safe...
also replaced the resistor I mentioned earlier...unfortunately, I don't have 1 of the 2 caps on hand, nor do I have a replacement IC as of yet, so will be tomorrow before I will know the results of this(without the ic-next week with the ic)...Anyhoo, thanks for the advice and will keep everyone posted on my progress. :)
[Edit]
Just got in touch with Pentranic's tech dept, and they say to check d501 as well FYI
Just throwing this in for Arm123 ;)
Arm123:
Thanks gokun. Some great Pentranic information here.
Unfortunatly, i didnt get to go test my mods that i made this weekend. I got too drunking on Sat night :P
Ill update as soon as i am able to test.

No worries; turns out I found a guy in town who cross-referenced the parts for me and got me what I needed so I have everything except the IC from the sub-power board(which is on order). I'm going to install after work tonight and see what happens...will let ya know.
Rickn:
I think you may have already told me.... but I get a lot of e-mail and sometimes lose track.. Where are you located (for some reason I thought here in Canada, perhaps even Toronto??)
If so drop by and I will give you one of the small regulator board.
Good Luck
Rick
gokun:
Unfortunately I am in the USA but I would be happy to paypal you the shipping or whatever, just msg me.
[Edit]
and if you're talking about the little sub power board(don't forget I'm still a noob to this so not up on all the terms) then it turns out I will definately be needing that after blowing mine up. ;) So please get in touch. thanks!
**********************
Now for my update....after replacing everything I mentioned, I fired up the monitor and......
it worked for about 5-10 seconds before blowing the hell out of the transistor above the ic on the sub-power board....I'm thinking I replaced it with the wrong one...or maybe the diode I replaced? Definately looking for expert opinions here as far as proper part #s and specs for the stuff I replaced on the sub-power board and d501...I'm thinking maybe I replaced something with the wrong part? Opinions and advice please!
That being said I feel like I'm close provided the sub power board is not fried completely now (there was a small orange hadoken before I pulled the plug and the board appears a little burned, obviously)...but I figured I would give myself a break and wait until tomorrow evening before pulling the chassis back out again, etc. Also hoping to get some feedback first before I proceed...but like I said, at least it didn't chirp...it actually powered on normally, then blew the sub power(well, I say it powered on normally but perhaps I should say seemingly...you know that regular little hum noise you get when you turn on a working monitor before it displays? It did that....then blew).
So I guess that's better than nothing at all....or more of that damnable chirping-lol!
So there you have it as of right this minute...the saga continues...
[Edit]
Well, you shoulda known I could not resist at least looking at it....
parts that blew:
the fuse
the transistor above the IC on sub power
a leg of the IC on the sub power board
possibly r515 on sub power board(haven't checked-just eyeballing it)
the fuse is easy enough, so I need some part #s/specs on the rest to ensure I have the exact right parts on hand next time...and of course, still need the expert advice in general. TIA!
