Hi there!!

It looks like your problem would be your Voltage regulator has either went bad or if your radio is mounted in a truck that vibrates alot then one of the three legs of the Voltage regulator has broke loos from the board. If you do not have experiance in electronics or soldering you should let a Radio Tech. do it for you or you could damage the radio!!! If you choose to do it your self then you must disconect from power then take the covers off of the radio. Turn the radio up side down and look inside the radio you will see the PC board has many compnents inside and beside each one there is a letter and numbers followed by the letter. look to your right and you will see a smaller PC board mounted to the right side with 2 screws to the out side of the chassis. Remove the 2 screws and carfully move the board out of the way so you can see the main PC board. Look down on the right edge of the main PC board and you will see a small black transistor with 3 legs on it the number on the PC board is TR41 when you find it turn the radio over and inspect the 3 legs that are soldered to the PC board and look for a crack or loose solder joint if you find one resolder it or resolder all three legs. If there is indeed a crack or bad solder joint then resoldering it should bring it back to life again!! If not then you may need to replace it with another one!! There is another transistor not to far fron the voltage regulator that may have went bad too it is TR40 that works with the regulator but is unlikely the problem but you never know. Try TR41 first it should fix it for ya. Feel free to E-mail us with any other questions that you may have at:

Thanks Dennis

Now put the meter on ref , key the mic and write down that number. Now go to channel 1 and do the same. If your numbers are under a 2.1 you are ok. you should also check it again on channel 20 or 19.

My dish remote wont connect to the dish reciever

If you have a single mode receiver, you need to open the panel in front and push system info.
A channel number will appear near the bottom of the list of information... it may be between 1 and 15. Push the record button on your remote control. (the black button with the red dot). If the channel number changed, then your remote and receiver are not on the same channel. Assume your channel was #1. when you first pushed sys info. You need to program your remote to #1. On your remote, push the Sat button until all other top buttons light up. enter the digit 1 and then the # key. Press the record button 4 times. You have to make sure you have the correct color key inserted in the remote control. If you have a dual mode receiver, one remote key will be green, and the second channel remote will have a blue key. Go to the Dish network website tech portal ...Google will help you find it, for complete instructions from the horse's mouth.

Cobra 29 LTD classic LCD channel display replace

Hello, the channel display is kind of touchy, as far as getting to it and of course it is soldered to a small circuit board and there is a certain way it goes back in. There is about 9 legs on top and 9 on the bottom that need to be unsoldered and resoldered( carefully). You can buy them in red,green, and bue. The meter light is pretty straight forward. You have a hot and ground wire. I used to use colored LED lights in the meters, way cool. They are not hot, and they last almost forever. The LED's are fairly easy because if you hook it up backwards, it just won't do anything. Let me know if you feel comfortable doing the solder work, and take a look inside the bottom cover at the channel selector because it has to come out with the channel readout. I used to charge $25.00 just for that because it would take me an hour just for the ch. selector, and about 15 min. for the meter light. Let me know one way or the other,,, Mechanic
