The laquer removed is actually on the LCD display pcb. I havent been home yet to check. I had tried the other mods and fixes and still had a hum. Removing the laquer, which does nothing but enables the screws to contact the copper grounding of the pcb to the frame, was the only thing that eliminated the hum 100%. I did notice on the repair paperwork that a ground wiren was installed. I'm hoping that is an indication of better grounding. We will see. I'll keep you posted once I get home and see and hear the results.
On return of my sds200 from uniden repair for the screen flicker and having the screen replaced as the repair I can report no hum. To recap,, I was worried that since I did the laquer removal on the display pcb, which was replaced, that the hum would return with the new display pcb. It did not. For now at least.

How about a sds200 that did it one time “ flickering“ and then never did it again ?

Mine was very intermittent. It did it pretty bad one day and then nothing for weeks. A slight flicker returned so I sent it in.

Pretty quick turnaround. LCD was bad. Cross fingers all is well going forward.

So just to update, shipped out on Feb 24th, returned to my door on March 7th, less than 2 weeks with shipping time. Thats pretty damn quick!
And, the screen works flawlessly, plus the unit itself seems to be a lot quieter. Pleased with Uniden's response on this one!

Does anyone know if a G 5 pager will receive DMR radios transmissions. Our local VFD went to DMR on VHF Freq. and we cannot hear them on a scanner .

I bought by SDS200 on 5/2/2020 and sent it to repair on 6/6/20 for the flickering display. They received it on 6/8 and I finally received it back on 7/13. They replaced the LCD display and a ground wire. It is working now - with no more flicker.

Good to know for those wondering about if Uniden repair is open and if so, what’s the average turn-around time on getting your scanner returned to you.

I had the flickering display on mine and sent it in for repair back in November..... had it back on the shelf in about two and half weeks. Great turnaround..... Just noticed tonight it is starting the flickering again. So if you have screen replaced there's a good chance it'll come back and bite you again at some point....

First, thank you for the heads up. I truly empathize with you, hoping my two SDS200’s remain trouble free.

Secondly, your assumption “there’s a good chance it’ll come back and bite you again at some point” causes me to wonder why you have come to that conclusion. The fact that it did happen to you twice causes me to think of the old adage “If it weren’t for bad luck, I’d have no luck at all!” But is it a case of just bad luck or is there more? ...A quality control issue with the displays? ...Or just a few bad apples that got by the quality control process during manufacturing?

Overall, the number of SDS200’s in use must be in in the thousands or tens of thousands. Most perform as advertised. And while there’s always room for improvement, all reputable companies offer warrenty repair service, and reasonable repair rates for their equipment that is out of warranty. We all expect that and would not do business with a company that didn’t. The simple fact that repair service is even offered is born out due to those instances where something got by the inspectors. If the manufacturer didn’t stand behind their products they wouldn’t be in business for long. But I digress... you already know this crap.

Which brings me to my main point... of the many SDS200’s currently in service, how many do we know of that remain good as compared to how many go bad? We haven’t any idea. We only see posts on the newsgroups from those with problematic radios (except on those few occasions where someone will answer a post with “Mine works great!).

Your assumption that if it happened once it will happen again is based upon what? My meaning is your assumption could very well be true. I’d just like something more to justify your findings. If you know that Uniden has stated there is/was a problem with flickering displays, you didn’t mention that in your post. And since I haven’t seen anything from Uniden I wonder if I may have missed something.

It’s true, there have been others with the same problem, but overall, it’s probably a small percentage of the total... maybe as low as less than 1%? And while Uniden has always been tight-lipped about everything, maybe something from Uniden has leaked out regarding the displays that I missed. Hoping you can shed some light on this.

Again, I do not doubt your findings. I’m just trying to determine if it’s a wide spread issue that Uniden has decided to deal with by simply replacing the display instead of improving on the display so that it doesn’t happen in the first place. The difference in your case seems to have been handled by the former, not the latter... and if true, that would suck.

Here’s hoping your quick repair turnaround you experienced the fist time will also apply to your second time. COVID-19 seems to have thrown a monkey wrench into the “timely turnaround” repair process.
