Here you have some schemes of other models, maybe the voltages are similar, but anyway you could at least see what the LED flashing means:

How to change a light bulb on my Frigidaire oven model RT 70 light bulb in the signal light area in the surface unit switch?


Hello Heidi, thanks you for your inquiry!

From the information you have provided you need to change the light bulb inside of your Frigidaire Imperial Electric Range. This appears to be an older model and I was unable to locate any direct information on how to change a bulb. Since your appliance is older than ten years old the manufacturer may not have any information for it. You may need to perform a generic search online for further help with the bulbs or speak with a local technician. I hope this information is helpful. -Matt

How to reset the lamp timer for Panasonic DLP TVs.


When you replace the lamp on a Panasonic DLP or LCD TV you will need to reset the lamp timer to zero for the TV to reset the lamp timer and extinguish the change lamp indicator.

There are two methods used depending on which model TV you have. The older units use the first method and newer units use the second method. You can tell which method you need to use by whether you have a PIP and/or SPLIT button on your remote. If you have them use the first method, if you don't use the second method.

Method number 1 (for older units):

Follow the procedure below. You use either PIP or SPLIT button depending on whether your remote has SPLIT or not. Some do not.

Perform lamp timer reset only when the lamp has been replaced. The idea is to know when to replace the lamp before the end of it's life when it could explode or short out causing a hazadous condition. If you reset the lamp circuit at any other time the replace lamp warning will not come on at the recommended interval.

Be sure the power cord is plugged into a properly grounded wall outlet.
Then, press the POWER button on the projection display or the remote control to turn the unit on.

While pressing the VOL- button on the projection display, hold down the
PIP or SPLIT button on the remote control at same time for more than 5 seconds.

If your remote does not have a split button you use PIP, if it has a split button, you would use SPLIT.

When reset procedure is complete, the screen on the TV will indicate that the lamp has been reset. When lamp time reset is finished, the LAMP indicator goes out.

Method number 2 (for newer units):

Press volume down on the TV and the zero button on the remote at the same time for longer than 5 seconds and it will reset the lamp to zero.

These procedures should reset your lamp timer and you will be good until the current lamp fails or the change lamp indicator illuminates again signalling that it is time to replace the lamp. Three to six years on average depending on how much you run the unit per day. Do not ignore the indicator. Change the lamp immediately to avoid further damage and expense or worse.

Thanks for using FixYa and for the great rating.

No sound on magnavox 50mf412b


Check the speaker/s first. If found OK, check and replace damaged component/s at its audio output stage circuit. Check all the soldering terminals at this stage circuit, for any loose solder terminals. Re-solder all the suspected solder terminals, by applying a little more solder. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts. Check the site in 'Mosaic' view. It will make search easy.

I need to know the seer number for an air handler. I'd


On the air handler take the top panel off, look to the left on the inside, this will give you general information on the unit on a stampede plate. This will
give you the date of manufactuer as well.

On the outdoor unit, there is a stamped plate on the
condensing unit. Should have year of manufactuer, it
should also say how many pounds of freon should be
in it. The Model number is what you need to know
to find out how big it is.

024=24,000 BTU= 2ton unit
030=30,000 BTU=2 1/2ton
036=36,000 BTU=3ton
040=40,000BTU= 3 1/2ton
and so on.

My guess is that it is an older unit and since I have
been installling units since 1995 I have only known
any older units to be at least a 10 SEER and no more.

Cannot get a GPS signal to my 525c DF


This may or may not offer help but on the lowrance site it has very simple step by step instruction to solving this problem. The first step is to make sure your getting power to the new 4000 series. With a 12v tester you can do this. On the gps unit there is 3 different power sources. One is main power, two is sonar and three is power to data. One you have power going to the 4000 then proceed to other options. I hope you didnt pay full price for your 4000. Lowrance has a replacement process and replaced my 2000 for a 4000 for $120 (2 day shipping). Back to your situation... Out the back of the data will the a cord that connects into the bottom of the T, and the a resistor on one side and the 4000 on the other side.

No AC from older Intertherm split system


It sounds like you are low on refridgerant. Double check to make sure both fans and the compressor are running. If so then you have a refridgerant problem.

WILL I NEED INTERNET ACCESS


I can help you ...

Are you referring to the base kit for manufacturing floors ? What is the model number of your base?

I suspect when you say base you are actually referring to an access point. It would likely be model 5131 or (older)4131.

That access point can support many devices. Hence you need only one. Be careful to turn on WEP encryption (or TKIP) on the access point so you don't become the next TJmax!

Hope it helps.
