Make sure the lamp door is pushing the safety switch all the way in. or you can push it in with a screwdriver and power on the projector. if it works then your lamp door is heat damaged and should be replaced. if not then your power supply is bad.

Will not start


More information would be nice. How old is the cultivator? How long has it been since it last ran?
Possible causes for the primer bulb not to fill: 1. the bulb has a small hole in it (need to replace the primer bulb, usually a pretty easy job, just remove a couple of screws, remove the old bulb and install the new one). 2. One of the fuel lines may have a break or hole in it. If the cultivator is old enough a fuel line may have dry rotted and came apart.
A couple of things to try: Put fresh fuel in the tank then remove the air filter and put a few drops of fuel in the carburator then try to start the unit. If it starts an runs for a few seconds and dies the problem is the carb. is not getting fuel to the engine. If it still will not start check the spark plug. Is it fouled? Worn out or broken? If in doubt replace the plug.

Sounds like air in the system, take spark plug out, pump bulb 3 or 4 times, replace spark plug and try to start. Repeat.

Won't start but cranks has 300k miles. Check fuel pump working, replace glow plugs, checked fuses and relays, fuel pump won't come on but works hooked it direct to battery, wait to start light does not...


If you can't pull the codes from the pcm it has either died or lost it's ground assuming it has power. I would try to get a wiring diagram and check both the power and the ground for the computer itself, because it is what turns on the pump and the wait to start light.

How to troulbe shoot my 300-Watt Power Pack/Timer. it doesnt turn on but it does turn off on time. had this product for 4 years and just now started having problems with the timer.


'Harry' wrote to me yesterday with handy malibu information.
1) Power packs come with 5 year limited warranty.
He is contacting Malibulights.com for a refund of some type.
Hope he writes back and says how that comes out.
2) He was having problem and plugged power pack into wall timer, then set timer.
Heh heh, pretty clever: Malibu transformer works, but timer doesn't, so plug power pack into a wall timer!!

That being said, I had same problem with my power pack.
I used blower to remove dirt and sprayed wd-40 and tried to take it apart.
My power pack was getting electricity.
Connections were good where lights tie into wire.
My lights never turned off.

Power pack doesn't come apart.
I turned it upside down thinking water got into timer.
I took it inside and let it warm up.
It still wouldn't work so bought another one.
Then I searched Intermatic and Malibulights.com for answer, but they have no troubleshooting or repair other than check electricity and check bulbs.
Conclusion: when power pack doesn't work, it is broken.
Unless you buy a separate timer and plug power pack into that timer as Harry suggests.

After researching power packs at Intermatic, Malubulights.com, ebay etc, the best I found were tips for next power pack that might save money:
The reason I add these tips now, before your power pack needs replacement is some fella wrote-in.
He bought 500 Watt power pack to replace 300 Watt > thinking bigger was better.
Power pack burned out. Here's why:
1) Match wattage of bulbs with wattage of power pack
-15 each X 20 watt bulbs = 300 watts, so install 300Watt power pack
2) Installing a 500W power pack on 300W of bulbs will burn out bulbs and power pack.
3) Replace bulbs as soon as they burn out or other bulbs will burn out and power pack will burn out.
4) When working on bulbs, unplug power pack or it may burn out.

Toro model number 200065 won't start. New gas, new spark plug, cleaned air filter. Doesn't feel like fuel is in the primer bulb when I prime it.


some toro primer bulbs don't fill up with fuel but blow air into a chamber in the carb that has fuel in it so when you press the bulb, the air sprays fuel into the carb ( just a little) So since it won't start, the bulb probably has a very small crack in it. replace it and then try it.

Lamp failure indicator


I had the same issue when replacing my lamp for the first time. I replace just the bulb with the Phillips replacement bulb. After installing the power down issue started and it would take up to 7 attempts before the TV would stay on with a picture.

Since I never had this problem until i replaced the bulb i decided to send the new bulb back and replace it with a difference one. In my opinion replacement parts are never made to the same standard as original OEM parts. This TV is definitely very temperamental in regard to the bulbs.

When the second replacement bulb arrived I decided to not only replace the bulb I also cleaned the connector plug in the cartridge with a QTip and alcohol. I did the same for the plug receptor in the TV.

When I replaced the bulb i insured the the top of bulb lettering was facing the handle of the cartridge so when you put the cartridge back in the TV the top of the bulb would be facing you.

I also cleaned the entire inside of the TV where the cartridge is inserted including the screws.

Once I did all this the TV turned on the first time and has been working fine for three days now.

I do believe the replacement bulb position is very important as to how it heats up and determines when it needs to cool.

I hope this helps others with the same success i had because I really do not want to replace this TV and start replacing all the parts others have done with little to no success for this issue.
