    Open and closed case...Envision TFT1780

    I have just come across this forum and am amazed and the level of expertise and help. You guys know your stuff! I am not a newbie but am a novice at the caps game and am having a heck of a time cracking the case on my Envision 1780 open. I have all of the screws out with the exception of the two small one holding the stand on the back. I have removed the white faceplate but cannot get to the boards. Can anyone please tell me how to open this thing up and get to the meat and potatoes of my Envision TFT1780. Thanks in advance!

    Cracked the case myself! pat pat on my back however, there are no bad caps that I can find and the power supply is an external brick supply that appears to be working fine according to my meter.

    The monitor is acting goofy...When awakened from a "sleep" the monitor has a bunch of "staticky wavey lines", it lasts for maybe 3-5 minutes then it works fine until the next time it goes to sleep. The monitor stays on 24/7 because the environment demands that it be. Thanks in advance for any help! Hammertime

      This could be bad caps that have high esr. As the caps warm up, their esr drops and the monitor works properly.

      To see if this the case, take a hair dryer and carefully warm up the caps on the inverter board first. If the wavy lines go away quicker, you know it is related to the caps. If the inverter board caps are not the problem, then try the caps on the logic board.

      Clear focues pictures of your board would also help. Please use the manage attachments button to post your pictures and please do not post inline.

      If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

      We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

      Please do not post inline and offsite as they slow down the loading of pages.
