This one should be a very close match. The T4508 is a foreign version of the T4500.
Try programming the radios without an eliminator code and see if they work together then. If so, there is something wrong with the eliminator code portion of the radio. Also, check your batteries, switch batteries between the units and see if the problem moves to the other unit. It takes more energy to transmit than receive, so a bad or very weak battery could exhibit a similar problem. The radio icon will illuminate whenever a radio is transmitting or receiving. When the radio is in standby mode, the icon should not be shown. Your radio with the icon on all the time may be stuck in transmit. Check your PTT button to see if it is slightly stuck or depressed.

Use scanning to monitor channels for transmissions or to find someone
in your group who has accidentally changed channels.
1. Short press MENU until the "Z" appears. The current setting
On/Off will flash.
2. Press either + or – to turn On or Off.
3. Press the PTT to confirm or MENU to continue set up.

One of my tlkr-t3 walkie talkie's will not recieve.
They worked fine the first time we tried them out. Then they were put away for several weeks, and when they've been switched on, one now doesn't send. I checked this by the other putting in scan mode but it doesn't stop scanning at the channel it is assumed to send with. I tried all the channels for sending but neither one is detected. The other way around, so the first one in scanning mode, the 2nd in send mode, works fine (the scanning stops at the channel of the sending one, as expected).
So my conclusion is, that one doesn't send.
I interchanged the (fresh) batteries, but this doesn;t change.
So what could be the problem?
