SOURCE: blank screen

Mine was doing this for a while and now is completely black all the time. I have a thought as to what this might be... I believe the problem is not the lamp or light engine but rather one of the brushless fans failing. This causes the tv to shut down as a safety measure because of the inability to purge the heat that would build up VERY QUICKLY and warp, damage and destroy everything else. I believe the problem being intermittent at first is due to the fan performing a "death rattle". The fan itself could be fine and more of an indirect problem. I believe the wiring coming out of the fan is inadequately insulated against the heat generated. It begins to cook, crack and eventually the bare wires touch causing a short or they just stop conducting altogether and fail.

The good news? You may be able to re-wrap the wires and be up and running again. If the fan needs to be replaced altogether, they cost about $15 and can be purchased on the internet. Nothing special about them. You would want to make sure it has the same leads coming out of the fan to facilitate the change-out. Again, I haven't attempted to install a new fan on mine yet but it will be the first thing I try.

If any of you attempt this before I do, please post your resulting experience for the rest of us. I will do the same. Good luck.

SOURCE: I have power to the spa, but it won't power up

there are at least two separate circuit breakers feeding your spa and two reset buttons. the circuit breakers are located a few feet away from the spa in an electrical box.

the reset buttons are in the mechanical space of the spa where the pump and heater are located.

SOURCE: Samsung 740N blank screen

That sounds like a capacitor or maybe a mosfet died. Usually only capacitors 'sing'.

first you need to confirm it is the backlight section that died. simple visual inspection. You want the monitor plugged into a running booted computer. If you have anything that will do dual screen that lets you know what and where something should be on the screen being tested.If not anything will work. Let the computer boot up and then you will need to get close and near an edge. What you are looking for is a ghost image of the normal desktop. You may even be able to see the mouse move around. This is the actual picture produced by the lcd. It is very faint. The backlight acts somehwat like a projector bulb and shines through the lcd panel. So if you can see anything then your backlight or the backlight power are the problem. I'm in BC so its hard to reccomend any place for parts. Most of the ones I have fixed the parts were out of California.Cost should be about $70-$100.

If the backlight isn't the problem then it is usually a power section problem. The parts are cheap but the time to find the bad one can cost a bit. If you can find a place to fix it get an estimate. Then check out the replacement price of a new monitor. The prices have dropped and sometimes it isn;t cost effective to repair even a backlight on some models.

How do you turn a balboa spa on?

Balboa does not make spas, just control systems.
but that is enough info to begin a troubleshoot process...
  • do you have anything displaying on topside control panel?
  • Fault codes?
  • When you say no power after connection to circuit what do you mean exactly?
  • Have you checked for burned system fuse?

My Spa has a Balboa 500z Top side and control panel. It was running at 104 degrees and then one day it just shut down. The Circ pump won't start up at all and when I first turn on the power, I hear the...

Turn breaker power off. Verify now power to unit with volt meter. Most systems have in line over temp over current to protect circuit board and motor. Also the water level switch must be made to complete interlock condition. Check the heater coil for continuityas it may have opened. Check heater for continuity to each coil set. There is an interlock that is for diagnostics on start up that will prevent unit from starting. Look for any melted wires or components too. Always know and verify breaker settings. Verify your meter with known voltage reading first. Be safe my friend.

My pumps will not turn on. i have a ms501s balboa master spa. i checked the pumps and they worked good. but the control panel wont turn them on. what can i do?

Is there a message code on the spaside control panel? That would be important to know. If you see no error codes, chances are that you have 'dead' buttons on the panel, especially if you have tested the pumps via an other power source.

What is the difference between a Balboa VS500Z and a VS501Z

The Balboa VS500Z supports one two speed pump, an ozone, and 12v spa light and an optional circulation pump.

Whereas the VS501Z will support a two speed pump, a single speed pump or blower, an ozone, a 12v spa light and an optional circulation pump.

Basically the two are very similar except that the 501Z will support an additional one speed pump or blower.

The best suggestion if you are doing a replacement is to purchase one of the Value Pack Retrofit Kits available through Balboa. You basically get everything you need for the replacement, including the topside, cables, and overlay.

You can find everything you need to know about making the replacement on the following page:



Hope that helps!
