Question about ViewSonic N2750w 27 in. HD-Ready LCD Television

1 Answer

N2750W follow up

See my new note on the original post for my N2750W... it really seemed the first person answering the phone was pointing me in the right direction, and she was very unhappy when tech. support passed me back to her to find a service center without even trying to troubleshoot or confirm the problem. I thought the price on the power board might be worth a try as well. I found that one of three was probably a special version for europe that was free of certain hazardous materials, so that narrowed it down to just the two parts that were one number apart. Do you know if getting to the insides of the N2750W is simple enough?

Yes it's easy for the most part. You'll want to lay it down on the LCD face (use a bath towel or comforter.) With the back facing up, remove the four screws inside the stand base and remove the stand. You can now access two other screws over the plastic back housing just near where the stand was, remove these. Now the tricky part. The back is just a shell or cover (no wiring connected to it which is good.) It is held on to the front half of the housing and LCD face by clips. Take off all the cable covers if you haven't already and use the square holes on the bottom center of the tv as a grip. I was able to get the bottom left corner started by grasping the area mentioned above while pushing in on the bottom half of the housing to separate the clips. You have to keep tugging up on the casing or it will just snap back in. Once you get a few inches started you can use an awl, ice pick or small screwdriver and slowly work the clips apart. Take your time and be patient. Once you have it apart you will see the smaller audio board and the power supply board. The main board is behind the shielded area in the center. I ordered the PSU on Friday from the viewsonic online store so I hope that does it for $68+tax and shipping. If not the main board is about $220.

    So it wasn't the PSU board but Viewsonic Parts was kind enough to give me an RMA# and I shipped it back. After hearing about dc inverter problems on other posts and trying the "hold down both volume buttons on the top of the set at the same time check" and noticed that I got a big blue square in the center of the screen it was easier to see why it wasn't the PSU. Something was powering the LCDs blue pixels so obviouosly the 120V to 12V and 5V PSU conversions were happening. Wish I new of this button test before I ordered the PSU. So I ordered, received and installed the main board a week ago and it has been working just like new. I would highly recommend this to anyone comfortable swapping out motherboards or the battery in your first generation ipod. I just did this a couple of months back and this helped me in being able to remove the back case of the TV set off without damaging, or scratching it. This is probably the hardest step of the repair. See my other post for details on opening the LCD-TV. The main board is behind the shealding in the center back of the the screen. You have to unscrew the support screws that help reinforce the RCA connectors and remove the post screws from the VGA and DVI connectors. There are some cable connectors that also need to be disconnected. Again, if you've swapped out a motherboard before (other than a snap-in and screwless Dell) this should be no problem.

    There are two main boards listed on the web-site so call and confirm for your set. Mine was a B-00001786 Main Board priced at USD218.59 for an N2750W manufactured in Feb 2005

    Good Luck. I was glad to get my 2 yr old set back for about a fouth what I would pay for a new set.

First off I didn't reply not helpful. Secondly try to be a little professional! If not find a new job! Third this unit has both zenith & lg, please make a note of it! Sparky


Since you've started a new thread here rather than replying to the original, I don't know what the original issue was. If you'd like to re-explain the original issue as a reply to this thread, I'll do my best to help you resolve it.
Please include the manufacturer and model numbers of all equipment involved since there seems to be multiple units.
As an aside, most of the people answering questions here don't do it as a job. Many are just people like yourself that think they can help others. Some people however target the site as their personal playground, and although that's very hard to police with such a huge site, I am sure that whomever you are referring to has been at the least reprimanded if not removed from the site.

Again, if you repost your issue using the REPLY link here, I will personally get an email when you have done so, and I will do my best to help you out.

I do not have my remote for my viewsonic N2750w. And i cannot find a universal remote that works. Can you tell me one that will work?


Hi,

You could order a substitute remote ( as original is not available any longer ) from :-

http://remotes.com/store/viewsonic/n2750w.html

If you want to buy universal remote, be advised that for Viewsonic it would not be too successful and moreover, the one which is compatible ( Harmony ) would be expensive.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Viewsonic n2750w


these boards are not componet level repaired so any componet could be at fault. almost all of the componets are SMT and are difficult to replace. it's easier to replace the board. some of the DC to DC inverters are not sold seperately and are a part of the whole panel.
