Have sound no picture?

I have replaced the lamp unit and the ballast unit and I still have no picture. Tha red light on the front stays on and the green blinks rapidly and it goes into cutting off and on 8 times and after that both red and green lights blink. I don't think the lamp is coming on, I know the fan is cutting off and on. It also makes a nosie when cutting off and on. Help!

If the fan is cutting off and ON there is a problem with your power supply unit.

and this may also affect your other systems on the unit

This model is prone to a lot of problems to the point where a year or so ago they offered a chassis replacement on an exchange basis.

I would with rear cover removed try to localize first where the sound or buzz is coming from: The ballast? the Light engine? The power supply?

I can help but as I said this model has a LOT of chronic problems.

I was watching tv and i heard a loud pop.then my picture went out but i had sound.red light in the front comes on model number is 50pl9126d/37


Hi,
If it is a lamp led light in the front panel, this is an indication that the lamp is not working. Pop sound was came from the electrolytic capacitor most probably in the ballast board that's why the lamp is dead. When the ballast board gone to malfunction, no high voltage will feed to the lamp resulting to that kind of symptoms.
Faulty capacitor has a physical indication of fault like bulged/dome at the top. Check the ballast board and inspect the capacitor. If you found it faulty, I would advice you to replaced the entire ballast board if you can't troubleshoot it yourself. Click this LINK for the replacement.

Also, check if your unit is still under warranty/extended warranty period, avail it because the manufacturer will fix it for free. Opening the back cover will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

My picture when out and the green light came on the front labled lamp. i replaced the lamp and it is doing the same


Make sure you replace the door to lamp back on the set, as the unit will not work if the door is not reinstalled. This is a safety feature.
Make sure you reinstall it correctly and securely. If this still does not work, then you might consider replacing the ballast also. It is the usually called the lamp driver. Its used to light the lamp. When you cut on the set listen closely near the lamp housing for slight clicking sounds, this is an indication the ballast is trying to iginite the lamp and that its ok..

Sound no picture?


I have no solution for this problem and I'm not sure I can fix it without taking it to a repair shop. The replies I got yesterday did not help.

No picture, no sound?!?!


This could be a number of things. Your lamp could be bad or it needs to be reseated to the ballast. The lamp is trying to light and it will make the ballast flicker (that is the clicking sound) or your ballast is bad and it needs replaced (it will flicker and click too). Or your color wheel is broken and it will make a clicking sound when turning. If the color wheel is not spinning or broken it will not light the lamp. No lamp no picture.

No Picture


its probably the ballast that is bad, call Optoma and you can buy a ballast for it, but you will probably want to have a pro do it, changing the ballast is a lot more involved than just changing the bulb, the ballast is what powers the bulb and it does go out on occasion.
