Is it worth getting a TIU fixed?

John,

It passes power through, but the DCS does not work.

If any channel does not pass power, open the TIU and check the fuses. Replace any that have opened.

Next, check to ensure that the DCS signal is on for all channels:

Menu/System/DCS Setup and press the AON soft key.

This and a whole lot more is all in "The DCS O Gauge Companion 2nd Edition", now available for purchase as an eBook or a printed book from MTH's web store site! Click on the link below to go to MTH's web page for the book!

John B,

   Take Barry's advise, more than likely you have just blow one or both fuses and your TIU is not as damaged as you believe.

John,

It's not a fuse if it passes power through.Did you try all the channels? Does the red light come on inside the TIU when it's powered up?

If you find the signal is turned on using MENU/ SYSTEM/ DCS SETUP/ S3 softkey for all on, I'd sent it to MTH for repair being it's the current  REV. L TIU if the DCS.

Hi Gents

Thanks for the responses. I need to do more testing I think. My thinking the engines were starting up quiet may have been because there was no power! Also, I need to confirm no signal on all tracks (I'm sure we had the issue on more than just one track but I need to confirm)

Heres what I know for sure....

It powers up, both remotes find the TIU. The AON has been set. There is a visible melt spot above Fixed 1 & 2 In, and last week it was very warm in the corner above Var In 1.

Of course I left it at the layout today, so I cant post a pic.

I will report back in a couple days!

John,

Place a caboose with lights on the track to see if you have power. No guessing that way.

I know you said it passes power but at what level  Is it the same as the input  The melt on the TIU common. We added cooling fans to all of ours.    Sounds like the Power FETS are bad on the TIU board  MTH can fix it pretty easy  They cost about 6 dollars each and there are 4 per channel

Loose binding posts???  Probably not,  I guess when I read the part  about The "Clubs, tiu" I get the feeling it may have been over loaded , What type of power supply are you using?.
