• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I have an out-of-warranty Uniden BR-330T with a tilted LCD (see attached) and need either a service manual or information about how the LCD is mounted before I open it up and try to fix it. Is it soldered to the board or is it just wedged in and attached via ribbon cable? If anyone has a scanned/PDF service manual, knows what is involved in dismantling it, or has any internal pictures, please help.

Hmm, another question: has anyone else had, heard of, or even seen this particular problem before, or am I just that lucky? :lol:

I'm not 'that lucky" but I do remember a thread with others having this issue.
Was it on this particular forum? I searched up and down, and couldn't find a mention. :confused:

Yeah, pics would be great, thanks; if only to see the board/screw posts I'll be up against. The guy (shop) I bought it from asked his technician if it was an easy or doable fix, to which he replied "I can't get in there". Heh, made me think that there might be some kind of super-glued shielding or something 'in there'.

Hi here is pic of screen and board
Wow, that was quick, 4 minutes. :eek: Is that clear plastic? the only thing holding it in place? If so, maybe it just knocked loose in mine.

more pics (and there are six screws on the inside if you miss the top two you wont be able to remove the knob antenna board) and it is plastic covering the screen .if you take scanner apart just be very careful take your time i was able to solder a new serial port in now my scanner works perfect i had connection problems with scanner and computer had to hold pressure on cable to get it to work and new port worked perfect

Thanks for all the pics and info; was very helpful. I ignored the top two inside screws because they didn't look connected to the knob board, but sure enough, it wouldn't come out, so I put the whole thing back together, heh. :roll: Guess I'll have to try again.

It looks as if it's exactly the same as the 396. I can tell you it's not an easy process. The metal shield is held on by a couple of through board solder points that require quite a bit of heat but it's not too difficult. The LCD is the hardest part. It has a row of L shaped pins that are crimped over the edge of the glass. The bottom of the L is soldered to the board. You have to heat each one and pry it up a bit with a small tool.

It's difficult to say what is causing it to go all black. Have you tried messing with the contrast adjustment menu to see what that does? If nothing changes I would say that the LCD controller may be bad.

When I reassembled mine after changing the LED color I noticed a few small lines and overall darkeness on the display. I went back and reflowed the solder connections. After that it was back to being perfectly normal. It's always possible that there is a cold solder joint on one of the pins too.

Heh heh, well the black-out was caused intentionally http://wiki.radioreference.com/index.php/Uniden_scanner_test_modes ;) to show the screen alignment problem I have (that tilt of the screen is *not* from the camera angle or bad focus), guess I should have pointed that out. Thanks for the shield info though, it is probably quite similar. Perhaps I wasn't too far off with the super-glue comment. I haven't got it apart again yet, but as well as I can see inside, it looks straight with just the case off. I hope it's not just a malformed LCD...

On a side note, I just read your LED thread. Nice- I was thinking of doing a multi-colored mod with some tri-colors (that morph from one color to another automatically) like these: http://www.etgtech.com/2006/html/products.htm :cool:

I didn't read your post correctly I guess. I was thinking that the blackout was the issue not the physical alignment. I see what you mean now.

Thanks for the comment on the LED thread. I thought about multi colors too but I think they are the 602 size leds so they are super tiny. I didn't see any multi color on that web site in that size package. I don't see how anything bigger would fit without some serious modding but it's a neat idea.

Ok well, crap. Looks like I got a factory second or something. The LCD appears to be malformed. It's straight on the board. The crystal layer must have been impregnated at an angle. :mad: Oh well, it was worth a shot...

Photos are a bit blurry, low light and crappy automatic shutter, heh. No real reason to post, but someone might find them useful, who knows?
