The display is blank and I can't hear anything on the radio either.

In what way? Your cheapest option is probably to get it repaired. The displays in particular seem to have a much shorter lifespan than the rest of the radio. After that it's probably the harness or the antenna/connection. Never buy today what you can put off buying until tommorow. ;-) -- Ben Jackson http://www.ben.com/ |

I found this on Eastern Avionics website: page
http://www.avionix.com/navcoms.html You have to read about the 155 and 165 to determine what the 155A has! The KX-155A has a VOR/Localizer converter board and digital radial feature on the Nav side. It also has 32 programmable COM channels, remote channel increment capability, stuck mike alert and shutdown, bearing TO and radial FROM modes, internal VOR/LOC CDI Display elapsed timer, and full backlighting of knobs and buttons.. Hope this helps. Tom "Aaron Coolidge" wrote in message ... Mike Rapoport wrote: : The KX155 in my "new" airplane (Helio Courier) seems to have bitten the : dust.

Mike MU-2 I agree with Aaron, sounds like wiring problems. When you key the mike to transmit it takes a lot more power. May be a bad ground? Is the Helio 28V and the radios 14V (converter going bad)?

Allen It worked normally until one day when it totally failed, no display, no radio, nothing. It could be outside the radio but I can't think of anything that coincides with the failure. It is a 14V airplane with a 28V 155. I am planning of getting a 14V radio and getting rid of the voltage converter. I will probably get a 165 so that I can get rid of the VOR converter too.

What OBS are you driving? If it's a 208/209 they have the VOR/LOC converter integrated, so you don't need the 165. |

There are 2 fuses, one for the display high voltage and one for the rest. Their values are printed on them. You need to take the radio out & take the cover off to get at them. I think they're under the top cover. Remember which holes the screws come out of, they're several different lengths. -- Aaron Coolidge (N9376J) |

It is a 206 indicator so it needs a converter to work with a 155 or a 165
without a converter. I've pretty much decided to go with the following GMA340 Audio panel (integrated intercom allows getting rid of PS engineering intercom/CD unit) GNS 530 (gets rid of MD 441 switch/annunciator box and I am intimately familiar with it (big plus IMO)) SL30 (can drive existing indicator w/o converter and allows getting rid of 14/28 voltage converter) Retain existing KT76A transponder The 530 will drive the HSI and the SL30 will drive the 206 indicator with no switching between the two. The whole setup is .8" shorter, weighs 2lb less and has about half the wires connecting everything. It provides a large color screen with weather and terrain capability and WAAS upgradability.
