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!

Where Can I Find A Dash or HTC S620 / 621 LCD Screen Replacement?

Check out the T-mobile Dash LCD Screen Replacements available on ebay. Why ebay? They are the cheapest by 25 dollars or so.

  2. GrinningFool says:


    I am glad we were able to help!

  3. [Venkat] says:

    These steps “just worked” for me
    Thank you for making me happy :-)


  4. Mark says:

    Easy directions, great pics, worked like a charm.

  5. Jermaine Ross says:

    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?

  6. GrinningFool says:

    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!

  9. Jaime says:

    I droped my phone and my screen is totally white. The phone is working perfectly but I can t see anything. Is the LCD borken? Or just disconected?

  10. woodz says:

  12. Adri says:

    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!

  13. Tamil Devendiran says:

    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.

  18. Ed says:

    Your instructions were helpful! Thanks!. Everything works fine, I do have to open phone again maybe later I left the piece off on the volume. Good thing it has volume. Again thanks!

  19. matthew watkins says:

    Many thanks for instructions, i had cracked my screen, I ordered one via Ebay from the USA £16, followed your instructions – absolutely brilliant!!


  20. Stuart says:

    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.

  21. Stuart says:

    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.

  22. Stuart says:

    And I can’t send or recieve texts either!

  23. good article, i will add my feeds.

  24. I’m a big fan of this website and I read it regularly. Keep up the good work!

  25. jon says:

  26. Mariana says:

    hola tengo un htc s 620 que se rompio la pantalla y el liquido se derramo por el vidrio de adelante ¿alguien sabe como limpiarlo? porque se ve pero con mucho reflejo.

  27. GrinningFool says:

    lo desarme y sequen o abrirlo y poner en una bolsa y la de arroz seco
