Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

I have an optima hd180 that will not power up. The projector was indicating a bad bulb, so I replaced that with a new one. Now it still will not power up and the fan does not come on either.


Problem w/ OEM bulb, it causes a lot of issues from my experience. Your ballast might have gone bad, hopefully it's just that. Check the voltage output of the ballast, make sure you're getting the proper amount.

Sounds like you lamp ballast has gone bad. I good way to verify this is, when you press power on the projector look inside the lens. If you see a small amount of light, then the ballast is good, and the lamp is bad. If there is no light then chances are the ballast is bad.

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....


Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

KDF E60A20 screen goes blank loses sound for 10 60 seconds


I've had this same problem ongoing for a couple weeks. Finally, tonight it would shut off every 20-30 seconds, stay off for another 20-30 seconds then come back on. It turned out to be my bulb. I blew the TV out with compressed air, removed the bulb and disassembled it. Taking the bulb out of the plastic cage I then remove one of the metal screens at the top of the bulb, it just has little clips holding it in. I took a bottle of rubbing alcohol, some Q-tips and proceeded to clean the inside of the bulb through the screen hole. After cleaning the inside I put the screen back in, cleaned the outside of the bulb with a rag and alcohol, then reassembled everything. The TV is much brighter, I had to turn down the brightness setting and has been running the last few hours without an issue. You can avoid all this by buying a new bulb but I don't have the money right now to replace it and I'm cheap so I'll milk this bulb for everything it has. Heat kills bulbs so if you clean the screens and blow out the TV once every couple months you'll get a lot of life out of it..... I'm almost to 4 years on my original bulb and my TV is on constantly!! Good luck to all!!

Hitachi 55VG825 rear proj television blinking light and screen doesn't light up


Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
