Does it works besides the lamp? If so then this can be cheaply ordered from bluestar-online, Mcmelectronics, tritronics

How do I connect a warning/ignition light to my alternator?

Hi Glen
All depends what you mean by warning lamp.
Early Alternators used to have a terminal connected to the "Star" winding inside. A 12v lamp connected between here and ground will light up when a charge is available.
But.... the simplest method is to buy LED charge lamp which checked for voltages above 12v (12.5 to 14v} and lights up showing a charge. I can buy a simple device like this from my local Jaycar Electronics store. You should be able to get a similar device depending on where you are

Good Luck

I think that the led light burned out

You do know the lamp won't light unless the projector has an input source connected?
It's not designed to be repaired because there are safety issues in case you put too bright a lamp in, after all it is a children's toy. That said you have 2 options, take out the old lamp, and identify it, that should be fairly easy, or contact the distributors.

No sound or picture. red timer light on. wd60735

Hi there,

This model as 3 LED indicator lights:

1) Power/Timer 2) Status 3) Lamp

If "STATUS" LED is blinking RED:

1) Internal Fan has stopped. These tv's require fans, to prevent overheating and causing damage.

If "STATUS" LED is solid RED:

1) Circuit failure (short)
2) Disconnected DVI cable, chassis to engine
3) No LAMP-EN signal from Engine to turn the lamp On.
4) Ballast UART communication problem.

If "LAMP" LED is solid RED:

1) Lamp Failure - Lamp failed to turn On.
2) Lamp is broken (e.g. burst or blown)
3) Lamp turns Off during P-ON

There is no data relating to TIMER LED being solid RED.

Hope this helps.

Hi, We have a Toshiba rear projection tv model 46WH08G which wont turn on. by this we mean that the red power led light is on and weve noticed that the green led light alongside is flashing, which has a...

It sounds you need a new Projection Lamp; they usually last for 2000 hours or more. The led blinking is the lamp warm-up period and it fails now, if you replace the lamp be careful very static sensitive and blow the dust out with air while the TV is open. Hope this Helps.

Lamp hour reset

I don't thing that because you were not reset the time lamp used now your LCD projector stop function
What was exact the unit did? no power at all or some LED light up or flashing. In any case to reset the lamp time use you must enter when unit is on
As you mentioned you did replaced the new lamp, You should check again if you reinstalled properly the lamp and lamp cover because under the lamp cover it had a safety switch if this SW not active then the unit will be in protection mode
I sugges you to remove again the lamp and reinsert properly and secure the lamp cover and try it again and if it still is not go then let me know what are the status of the 2 LED

Energy S 8.3 Woofer; blue led doesen't light up

Bought a S10.3 in jan/2010, LED died a month later. I've repaired it by myself. After inspecting circuit, I've found that their design puts almost 14V of reverse bias upon that poor blue LED. These components are not usually expected to sustain more than 5V of reverse polarization. So, in my opinion, there is a design flaw. To make a long lasting repair, you just need to insert a general purpose diode in series with the LED, such as an inexpensive 1N4148 ($0.05). And, of course, any readily available 3V, 5mm, through-hole round blue LED (I think crystal clear should be better).

Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here

Hope this helps

Wd52725 problem

code 12 means no error detected. However when your lamp wont light and you have replaced the lamp it is usually traced to the cpacitors on the PWB PCB that need replacement. You can get a repair kit for that model at the following link. Its called the V26 PWB PCB repair kit. which contains all the capacitors and a CD with the capacitor board locations and disassembly instructions and board Identification and full Service manual for that model DLP. Heres the link.

Nokia 6233 water damaged...

Unfortunately, probaby both, plus the keypad, other selector buttons, camera and speaker.

Most likely would cost more to repair than to replace.
