My 2990 has an odd quirk. When i first turn it on the display lights (the bulbs) will not light up until after about 10 seconds then they will come on.. They display works fine its just the bulbs that act funny.. Anyone know why and can help out? The owner told me this will happen and he thought it was a cap going bad.

Cm3885,

Can't offer much help on Bulb's but be Gentle with it.

My 2990 in perfect shape is sitting here with a DEAD Display\Processor Board.

It did the exact same thing as your's and then quit completely.

I have ordered 6 Replacement Display's from Ranger for it and NONE of them are Compatible or will work. And even tried display's from Older 2950's with no luck.

So I have a Like New DEAD 2990 Sitting here.

The display boards are no longer being made but Tech8541 said they were supposed to make replacement's as far as a year ago and still none.

Good Luck and Talk Sweet to it.

I know about the displays not being made anymore but i think my tech has a few laying around and i think he can still get them from his supplier... :-)
How easy is it for the display to go bad?

Cm,

This is the 1st Display I have ever had go bad.

Mine has the DPT295042Z board in it.

All of the replacement's I have ordered have the Same exact DPT Board Number & Component's but the PLL CHIPS are Numbered Different.

Check with your tech and see if he might have the DPT295042Z Board with the PLL #'s below on it.

RANGER
YN2950DXSP
HD40481BG17FS
9941 JAPAN


That is the One I need to bring Life back!

I have ordered 6 New Board's with the 295042Z number on them, and tried maybe 10 other 295042Z board's but NONE had the same Chip as the one on My original board and NONE WORKED.

Darn UPS rates are breaking me sending them back.

Ill ask him. Getting ahold of the guy is about as tricky as finding parts for a radio that hasnt been made in 30 years!!! LOL!! He works 2 other jobs and getting ahold of him is like touch and go. Ill write those #bers down and ask him next time i actually can talk to the guy. Ive never actually had a display go bad but you never know.. I had a 2527 that i though had a bad display and it was only a short on the ciruit board.. maybe the problem with the lights may be a simple short.. I called my local CB shop and the guy said he has seen several 2950s and 2970s and a few 2990s and 2527 with my problem and it was caused by simple bad connections, poor solder joints, parts going bad, and the radio sitting for a long time not being used.. I hope my problem is as simple as that 2527 i fixed up a while back!!

the last i heard from rci is that the cpu for any of the 2950's besides the dx version are gone and will never be brought back again.

i had to get on rci for saying that the new version (can't remember the ept# right now) is a direct replacement for the older version (ept295042z). the 1st few batches (made when the 29xx radios were being made) were direct replacements, but -ANYTHING- in stock now is not. i have a pretty good relationship with rci in the technical dpt, so if you don't believe me, then just order one.

you must go by the markings on the chip to know if it will work with the older 29xx radios. the chip must have 'sp' in it somewhere like tech808 has in his above.

I AM GOING BY MEMORY HERE. ALL EXAMPLES/NOTES ARE AT MY SHOP. IF/WHEN I GET TIME WHEN I AM THERE, I WILL RE-POST IF I AM WRONG.

Thats too bad too as there are millions of the pre DX radios out there all over.. and most of those guys wouldnt trade them for a DX ranger fot the life of them! Ranger is stupid to axe the parts for the pre DX rangers.. But what do i know im not a tech just an end user.. Ive noticed here were I live no one wants the DX rangers at all..

disinformation from techs who don't know/want to work on smt goes a long way... lets just say that in my area, no one has a problem with the dx series.

the reason rci gives for why there are no more cpu ic's for the non-dx 29xx radios is that the company that made those cpu ic's (supposedly rci does not make their cpu ic's) will not make any more of those non-dx cpu's ic's. as far as i know, there are only 3 new non-dx cpu's in existence, and i have 1 of those. this comes from some long searching and the right contacts.

8541 knows the world is going SMT. Its that way in most of the parts world. Today if you want things with leads to solder to you better stock up on them. ALL the new radios that we are using at the jail are SMT boards most intercomes most alarms and most CCC ( video ) too. For 20 + years i have used in many projects minicircuts amps I LOVE MAR-6 amps they made very tiny very wide band .... and being replaced by ...... you guest it SMT ONES. Bottom line you either get with the program or get left behind ........... punched through soldered boards are not comming back no matter how much some may wine.

Yeah we all know everyting is going to the SMT radios but what do you do when you need to get one repaired? there isnt ONE tech here were I live that will touch a SMT radio with a 50' pole. If you have to send off the radio to a far away place to get it repaired and play the waiting game who wants to do that??? NOT ME! I own a 2970DX and its ok but i sure as hell dont want it to go bad. cant do any repairs myself and my tech hates SMT radios..... Oh well....
JMHO SMT radios are junk... Take it as it is.. give me an old through the whole board radio any day!!

SMT is not all that bad to work on all you need is a hot air desolder a 100X mag glass and very good tweezres and your all set.
