I am new to the forum and was wondering if there is a way to replace the LCD screen on my thermostat. It works fine but I can't see the screen, might have got a spike or something.
Its a Robert Shaw 9701i
I would suspect that Robert Shaw would send you a whole new thermostat if you sent them a email about the problems you are having, or maybe offer you a replacement at cost, that would be far far cheaper than buying a new one. I doubt that any display that they use would be a universal one that can be bought "off the shelf"...its probibly a highly specialized, one build just for that model unit, only available by them. Robert Shaw seems to be a pretty reputeable company.
Its funny how many companies will send you a replacement unit, if you simply just ask nicely.
A display on a cordless phone died prematurely larely, and I sent it back to the manufacturer. Lo and behold...2 weeks later I received a whole new unit in the mail...surprise...surprise.
I called customer support and explained that the unit was only 17 months out of warranty and did not get anywhere with the young lady.
I could try again and maybe get someone more customer friendly.
If they still say no, I might just send it back anyway.
You don't ask, you don't get!
Thanks for the reply
It's rare that a bare LCD like the one in the picture will fail altogether, and it looks like there's no separate controller chip.
You haven't actually said that you tried new batteries or that you confirmed that the connections were clean. In addition, you should get a voltmeter and see that the battery voltage reaches the board. If you don't have a voltmeter, test the batteries in a flashlight or something.
My theory is that the thermostat itself is operated mostly from the transformer input and the battery is really only to run the display and to keep the clock functional when the power is out. That's how mine works.
Hones, I'm not trying to be flippant. Batteries really do cause problems like this.
