How to Replace the LCD Screen on a T-mobile Dash
This is a how to repair guide for the HTC 620 / HTC 621 mobile phone. Commonly referred to as the T-mobile Dash. For some reason, the LCD screens on the Dash seemed very prone to breaking if you carried in your pocket or dropped it once.
The good news is you can repair it yourself. A new LCD for the t-mobile Dash runs about 30 dollars on eBay and the procedure is pretty straight forward. Be glad it’s not a slide phone! Yeesh, changing LCD screens on that type of phone is a pain!
Check out the T-mobile Dash LCD Screen Replacements available on ebay. Why ebay? They are the cheapest by 25 dollars or so.

This guide is for replacing the LCD on your T-mobile Dash. This will fix a dead back light, no display, cracked LCD screens, shattered LCD screens and just dead Dash LCD Screen in general. If you have an HTC Excalibur with a broken screen then this procedure will work for you as well.
So without rambling by me, I present to you the HTC 6201/621 Dash LCD Screen Replacement Guide!!
Tools needed:
T6 torx Driver and some type of flat tip device for prying covers off. A plastic guitar pick is my favorite choice.

Thanks alot! Your guide was all I needed to install a new lcd screen. I ran into a problem afterwards though, I can’t hear anything on my phone unless I use the speaker phone or a ear piece. I was wondering could it be that the reciever copper pins aren’t making good contact with the copper padding on the pc board?
February 4th, 2009 at 7:05 pm
I would go back and make sure all the connectors are tight. Especially the one in step 9

Thanks, you saved me extra time. — I bought the screen off of ebay and they sent me a link to a uTube video with instructions. (BTW – very useful, it made me feel comfortable with the clicking and popping sounds of seperating all delicate/breakable pieces – LOL) but unfortunately it only showed the steps for taking it apart. When I first turned on the phone I got a white screen, kind of figure it was one of the connections and decided to search for help so as not to waste time. Found this article and your exact description of each connection, let me correct the problem in a few minutes. The upclose pictures you included were very helpful as well. If I can add a tip: for those not used to working with the insides of electronic components, taking the phone apart is a good time to use compressed air to clean all the dust and dirt that gets inside, despite the housing being sealed. I’ve had my phone 2+ yrs and was amazed at the dirt inside. — Thanks again!

Thanks so very much! Your guide was all I needed to install a new lcd screen. I had never had a cell phone open but you made it very clear and easy to understand step by step how to do it. The only problem I have had is I can’t use a corded handsfree headset because the mic doesn’t work. I got the phone cheap because the screen was screwed up so I hadn’t tried to use a headset before I replaced the screen. Therefore I don’t know if it worked before or not. The screen is perfect now tho! Thanks again!

This was the best thing ever I followed the directions exactly the way it said my cousin gave me her old one and I just switched the lcd on it and it was just like new!

This can’t get better. After T Mobile had let me down to fix the LCD screen, I decided to follow this article. Its very simple and I have replaced my cracked LCD screen in minutes…Now my HTC Dash works like magic…Thanks. Without these instructions I wouldn’t have fixed my mobile.
July 16th, 2009 at 8:53 am
I BROKE THE SCREEN ON MY DASH BUT THE PHONE DOESN’T SEEM TO BE WORKING PROPERLY. THE LIGHT DOESN’T FLASH WHEN IT’S ON. COULD THIS BE BECAUSE OF THE LCD OR JUST SOMETHING ELSE?
July 20th, 2009 at 6:05 pm
Thanks man, i disconnected the interface with the red and blue cables, i forgot the right position when i was replaced the screen.
Thanks good job

I replaced my screen following the instructions above. By the card in step 9 there was a srew which had to be removed before I could open it up. After removing this screw some bits at the top came adrift ( by where the earpiece is). On putting everything back together it all works fine except, when a call is connected I can’t hear them and they can’t heare me. The LCD by the earpiece is working fine. Is this to do the what came loose or is it likely just to be the connection on the cable in step 9 as was mentioned in a previous comment.

Following the previous comment, I reattached the cable and tried the phone before I had screwed it together, it worked fine. The next day the microphone/phone speaker are not working again.
