this address should help you out http://www.ham.dmz.ro/yaesu/vx-1r-ext-mic-diagrams.php
as for the service manual you will have to order that from yaesu or see if the local Ham radio sevice shop has an extra one they will sell.

Hi,

Here you can see the schematics http://www.repeater-builder.com/yaesu-vertex-standard/ft-1500/ft-1500m-sch.pdf

The manual can be found on the Yaesu website, http://www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&ProdCatID=106&encProdID=92FB2363C1E0B9EBC9D3479054E0120B&DivisionID=65&isArchived=1

Good luck,
Gerard

Thank you FixYa team support, I already find the solution.

check the resistor values around the finals and also around the stage that drives the finals and see if they differ from the schematic values.

Reset the transmitter.

the Start button was not pressed; the door is not closed correctly; the child safety lock is activated; delayed start is active.

I suggest check the microphone connector and cable first. Are they OK ?

You mean FT-225RD not DR ? The RD is a base station all mode 2 meter rig. Older model. Set the Channel switch to VFO. Use the Band selector to set the vfo to 144, 145, 146, or 147 mhz. Then turn the vfo knob to select the frequency.

You mean the Morse Key?

Could just be a noisy power supply or a poor ground plane.

Check all coax connections, make sure power out pit is tuned , check all switch's for receive can't get anything in or out , finals may be blown , i liked my old 101 but it sure doesn't like to take any abuse , good luck !!!

The problem is likely the TX/RX relay. If it is old (and I am sure it is) the contacts likely need to be cleaned, or the relay replaced. It is a common enough relay if you want to replace it. Also, pull each PCB card and clean the contacts with a pencil eraser. Pink erasers are OK but the white ones are better as they aren't as abrasive. Hope this helps, VE3CMQ

a couple things you can try if nothing shows on the screen at all. Do a full reset first of all, that's the best step with any hand held radio problems. Try pressing F then 0 and if that don't work try battery removal and if you still get nothing time to call Yeasu they have always had firmware issues with handhelds I have a triband handheld that did the same thing

Check your transmit frequency to make sure it is within the proper range. Also verify proper battery voltage, it will typically transmit with low voltage.

I am not sure, but this usually indicates that the PLL has lost lock. These days, it could be as simple as a poorly soldered connection. I don't recommend that you try repairing this yourself as there are essentially no user serviceable parts in radios these days. Radio repairs these days have come down to board swapping because the parts are so tiny that humans have a hard time replacing (and in some cases, seeing) the parts. Yaesu US has a very good reputation for quality repairs so I'd suggest you send it there. They will likely just swap a board out, but that will be less expensive than having someone spending 10 hours trying to find the problem and repairing it. I know, as I work in a radio shop, and if it isn't something real simple, all we can do is do a board swap.

The microphone should plug into the side connection.

Check the fuses and the power supply. Make sure that the power supply has enough capacity to run the radio, at least 20A! Make sure that the power supply is putting out 13.6V. If you were unfortunate enough to hook the power leads up backwards, then a trace may be blown off the circuit board internal to the radio. Also, it is likely that the reverse polarity diode inside has shorted out. This may cause the fuse to blow when you apply power. If it has blown, it likely took the the trace out inside the radio. If the power supply and fuses are OK, unless you are competent technically, the only recourse is to take the radio into a shop and get them to fix it. If you were upgrading the firmware inside the radio when it happened, then the radio is likely non-repairable. I don't recommend ever upgrading a radio's firmware! If it isn't broken, then don't fix it!!

My guess is that the power supply you are using is not up to the task. You need one that will provide at least 15 amps at full output. Try setting your radio to a lower power setting and see what happens. You may find that you have to upgrade your power supply.
