Display on my Polar S-710 is bleeding....(8 posts)

Display on my Polar S-710 is bleeding....SS_MB-7

I bought a Polar S-710 2 weeks ago and am having intermittent display problems.

On my first bike ride last weekend with the HRM mounted in the handlebar mount (sunny day, approximately 25C), it appeared as if the display was "bleeding" around the edges and numbers. By "bleeding", I mean that several large-sized multi-colored blotches appear on the display for no apparent reason.

At the time, it was only an isolated case and seemed to correct itself shortly after the ride. However, the problem has become more frequent and is not isolated to being mounted on the bicycle.

Just this weekend with the HRM on my wrist (overcast, approximately 20C), the display showed more severe signs of "bleeding" around the edges and in the majority of the display. Similar to the first incident, after a short while, the "bleeding" would stop. However, the frequeny of the "bleeding" is increasing and is of some concern.

Then, this morning while driving to work, the display really bled. It appears that the film used in the LCD is somewhat distorted but only becomes a problem under certain lighting conditions (early morning/evening).

Interestingly enough, when the "bleeding" is not apparent, the display appears perfect.

It should be noted that the HRM has not been used or worn in the water, nor has it been dropped or abused.

Since the HRM is 2 weeks old, I'm assuming that this HRM will be quickly warrantied.

Anybody else had similar problems?

The display appears distorted when you look at it through polarized sunglasses. This is particularly true in the sun. Is this what you're experiencing?
Nope, it appears with or without sunglasses....SS_MB-7

Nope, it appears with or without sunglasses. I thought of that too the second time it occurred, so I made sure to removed my shades when checking....still there.

This happened to me with a digital watch several years ago, there is something wrong with the LCD itself. Give Polar a call, they have a pretty good service department. I don't think it is something that can be repaired, only replaced.

I think have the same thing with my 710. It sort of looks like an oil film on water right? To be honest I never though much about it. I think it's a combination of heat and the fact that the internals are plastic/flexible so things tend to warp a bit when they expand and contract at different rates.
Exactly! But, it's not constant....SS_MB-7

Yes, when it does happen, it looks like an oil slick on water. The unfortunate part, is it isn't constant. So, if I send it back to Polar, and they don't see it the first time they look at it, they'll think I'm nuts. I'm glad you see what I see.

The LCD display is bad. This could be caused by the seal around the edge of the sheets of glass being bad or because a small crack has developed in the glass itself. In any case Polar should take care of it or you could go back to where you purchased the unit and they will probably swap it out for another unit.
Thanks everyone. I've emailed and left message with Polar....awaiting reply. I'll post the outcome (nm)SS_MB-7
