Optoma EP 738 Temp n' Light Red; Power Flashing

When I plug my Optoma EP 738 in, the Temp and Light indicators are red and the power light flashes green. Is it worth opening it up to maybe clean up the fans, or is this a motherboard issue?

Also make sure the bulb replacement cover is on, cause there is a little switch that cuts power if the cover is off.

SOURCE: Optoma 719, can't get lamp and fan to turn on.

There is a stuffed 10v 3300uf capacitor on the power board. You need to replace it.
Bellow you can check in the picture where the capacitor is located.

Notice that in this picture I have already took the bad capacitor out and replaced with two small cords to reach the bottom and test the new capacitor.
To reach this place is not fast, several layers of plastic and metal must be removed, but is not a hard task to take the capacitor out and replace it for another.
It works just great! Now it is back on track with awesome image.

SOURCE: I have the Optoma ep719 and it will not power on.

some dry out, and you can't tell by looking at them. see if the colorwheel is spinning. if it chirps before it shuts down, or if it doesn't spin at all, replace it. otherwise replace the ballast.

Mod.Hp980PT, red and top green light flash, no heat


This is a very common feature on these types of simple, high-volume, low-cost home appliances known as a safety fault. This fault will temporarily (or permanently) disable the appliance and happens for several reasons: (1) an over-temp (high heat) occurrence, (2) an over-power (power surge) occurrence, (3) an under-power (power outage or trickle power) occurrence, (4) an over-time occurrence (auto-off fails), (5) a short-circuit occurrence (exposed/crossed/frayed wires, etc.). Fortunately, it uses a digital "fuse" system and can be reset by the user. However, there is no universal reset process on SoftHeat products so you just have to play with it until you figure it out (customer service dept is no help). Mine is a Kaz SoftHeat HP980PT, with a red power indicator/power-off button and 4 green heat setting buttons. Mine faulted after a heavy storm caused multiple power outages and power surges in my neighborhood. The green light on the highest heat setting button was flashing on mine. Here's how I fixed it: (1) unplugged both ends of power cord and straightened out the cord, then plugged back in to the heating pad end. (2) While holding down the flashing light button, I plugged back in to the wall outlet. (3) While still holding down the flashing light button, pressed and held down the red power-off button, then while still holding down the red power button, I released the flashing light button, followed by releasing the power-off button. This stopped the flashing green light and caused the red power indicator light to stay on (steady-on). It works fine now. Note: Some models have an actual hard fuse in addition to the digital fault feature or possibly only a simple fuse (without the digital fault system). These fuses can the found at many retail stores and then very easily replaced. I hope this helps some of you!!!

The problem with my projector is it keeps flashing green and red


hi,

your statement is not very specific but if the power led is flashing green and the lamp led is flashing red that indicates a fan failure.

contact optoma support here and enquire if you can have a warranty repair, or how much it may cost to have the fault fixed.

After changing the bulb image will not come on and solid orange light appears


Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.

You can test the power source if you are getting any power input from the power cord itself. Plug in your power cord and use an eletronic meter on the other end to see if you are getting the proper voltage (110/120) reading. If not, then the power cable is bad in itself. IF you are getting power from your cord, it could also be a fuse inside the Optoma and/or where the power plug on the Optoma meets the actual power source is out of alignment or may also be not making the proper contact to the main circuit board on the Optoma. Hope it helps....JGUAM
