Question about Toshiba 62HMX84 62" Rear Projection HDTV

1 Answer

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!
I got in the back and looked at the fan, it is running but it seems to surge and makes a nosie when it cuts off and on, is this still the power supply if so where is that?

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.

Replaced bulb yesterday worked fine. Today light will not turn on. projector turns on both lights green for 10 seconds, then power goes red and status blinks green for about 5 seconds, then status light...


green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

Telly on but no sound orpicture


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL2100 you can find it here http://www.discount-merchant.com/Sony-XL-2100U-TV-Lamp-p/sony_xl-2100u_replacement_lamp.htm?Click=48173 .Have a blessed one!

Lamp light on after i replaced the blown lamp Hitachi 60v500a


Was the tv working before you replaced the lamp? if it was then make shure you have reinstalled the new lamp and the door exactly as removed, there is a disconect switch on the door that has to close when the door is reinstalled,or sometimes the ballast may go bad at the same time.Hope tha t will help you fix it.

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..

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

Toshiba HMX94 DLP I replaced the bulb after it crashed and now red and green light flashes no picture. Please help. I tried two new bulbs. Mark T


The problem most likely is with either the lamp ballast or the light engine. The lamp ballast is the part that provides voltage to the lamp unit and is usually not all that expensive a part. The repair cost from a service shop can be about $300 or more. If you are handy, you can replace it yourself. Check out www.thepartstore.com for the ballast.
