SOURCE: new battery but lcd still no backlight

You probably have a bad inverter or backlight in the display. The inverter is what provides power for the light, and it's usually what goes bad. Replacements for most brands are available online from a number of sources. A Google search will usually turn up several, as well as detailed steps to change it if yours is a common brand. A computer service shop could give an estimate if you're not comfortable doing the repair yourself.

If the backlight itself is bad, that's much harder to change since it's built into the display panel. It's easiest to replace the display, but that can be a costly part. Most servicers won't try replacing the backlight because of the time involved. Again, get an estimate and then decide whether to fix it or replace it.

Hope this helps. Thanks for using Fixya!

AT2+ doesn't print

Its a common problem with Schiller ECG machine. The battery of your ECG machine is faulty. Even if you are using the machine in AC it uses the battery power. The AC power is only used for charging the battery.

When the machine starts to print the battery will drop down and the printing will stop. This is happening with the machine. It will eject the first paper without printing. its normal. Because the machine starts printing on a fresh page only. In your case the machine is ejecting the first paper. When the machine starts its printing in the second page it will draw a large amount of current from the battery for its thermal printing head. If the battery is not proper then it will suddenly drop the printing. The square box you see is not printed by your ECG machine. Its already printed in the paper of Schiller. With this mark the Machine sense the page.

Its a 12 volt 2.3 AH battery. You will not be able to replace the battery from out side any where. For replacing the same you have to open the machine by removing the screws on its bottom. Be care full with the paper tray while removing the top cover. Also do not use any force to open the top cover because there are connections on the top cover.
Here i have added a link to the battery for Schiller AT2 PLUS

The Schiller AT-1 is not printing, when the patiente cable is conected the unit start to print and stop after 1 second and turn off. If I disconec the cable the unit keep printing

The Schiller AT1 is a battery powered unit. A common symptom of weak/defective battery's is that it will stop printing after 1-2 seconds of run. As to whether the patient cable effects this, I honestly don't know, It really shouldn't, baring some very weird internal short in the cable. The battery in the AT1 is beyond the average user to safely replace. Before anything else insure that the AC indicator light illuminates when the unit is plugged in. If not, you device might have a defective power supply. In either case, the unit needs repair in a Qualified shop.

Machine only shows straight lines on screen and print.

you either have 1. a defective patient cable, or 2. a defective PC board. The internal problem is very likely the input connector its self, buy this is a multilayer board, and requires an experienced hand with a soldering station. Also note that if the problem lies elsewhere on the board and the board has been worked on in any way, Schiller will no longer exchange it. A new PC board(aprox2200.00) would be your only option. IF the board is returned to Schiller having never been worked on, they will exchange it for around 800-900 dollars. A far better deal./

High, I have a Schiller AT-2 light that is printing too lightly suddenly. Hard to read the lower page tracing in particular. Had it 5 years, doing well. Anything to adjust that?

Your machines thermal printing head have some problem. Thats why it give printouts very light. Not possible to repair thermal head. You have to replace it.

Why won't it turn on?

Sounds like you need a new battery. When they go dead you will still see the green light but it will not turn on or only on for a second.
