Thanks for the helpful info. I called the business where we purchased our TV from, and they came and picked up the light when they did some repair work for us. This is a small town, and they only have a site to drop off polluted things like this once a year. That was September 13th! This happened a long time before that date.

I don't know what location you live in, but if you are in the US, check your state's EPA webpage...they usually have contact numbers for questions like that (and if you call, they can likely recommend local agencies/businesses qualified to dispose of it for you).

I have a Hitachi LCD rear projection TV, model 50v720. As I was watching, the screen went out and the green power light and 2 red lights next to it started blinking, green red red, green red red, etc. it...

I'm making some educated guesses because I could not find the manual for your model. I'm looking at the manual for the 50VS69A. With that caveat having been said, my hypothesis is that you have an overheating problem. The second light is probably the temperature light. Check the vent slots in the back of the set and vacuum them out if they are plugged. Also, look for a dust filter or access door to the dust filter, and get in there and clean that out. Check your owner's manual for specific information; that may be easier than hunting for the filter. Next, feel for air blowing out of the vent near the lamp access door. On the 50VS69A it's on the back of the set on the left (facing the back), but on some models it's just to the left of the center under the screen. If you cannot verify that the fan is running, you may need to replace the fan.

You should clean the vents and filter on a regular schedule. Failure to do so will shorten your lamp life and otherwise accelerate aging of the components in the set.
Generally, once a month is sufficient.

Except for the last part and the length of time, the flashing light pattern you describe indicates normal power-on warm-up for the 50VS69A. It could very likely be something else on your model.

If the set is overheating, it will shut down everything. Most sets will also shut down if the lamp fails, but in that case the lamp indicator will be on. Check the label next to the red light to see which one it is.

Regarding lamp replacement:
Lamp replacement instructions are in your owner's manual. It is a do-it-yourself operation with some precautions given in the manual. You can save money by replacing the lamp only and reusing the original housing, but if you go this route, you must be sure you never, never touch the new lamp with bare fingers. If it gets skin oil on it, it will discolor and may even explode when it gets hot. The new lamp may come with a pair of disposable vinyl gloves (the same kind used for food service). Use these (avoid touching the outside of the glove fingers with bare skin) and you should be all right. You may need to polish the ring terminals on the lamp wires in the housing if they are oxidized. A soft white pencil eraser is best for removing a light tarnish. Be careful not to break the terminals off the wires.

The old lamp contains mercury. Dispose of it properly as hazardous waste. If its outer glass is not broken and you are sure it is bad (you can usually see inside it and can identify a broken wire or other sign of burnout), you do not have to wear gloves when you handle it.

How do I install the samsung HLR4667WX/XAA lamp...are there instructions that come with that part or do i need a professional to install

The manual for the TV usually has the instructions. You can find many Samsung manuals on their website ( The bulb replacement is easy enough to do it yourself. You need a Phillips screw driver and a lint free cloth to handle the new lamp. Turn off and unplug the TV. Wait ~30 minutes after turning off the TV before starting.

Usually you need to remove one Phillips screw to take off the lamp cover. Then loosen two additional screws and pull the lamp housing out by the handle. If your new lamp came with the housing, just swap. Otherwise (some OEM lamps), you need to remove 6 more screws to exchange the lamps (these have nuts that are only hand tight). Make sure not to mix up the old and new lamps and store the old one in a safe place until you can dispose of it.

Then reverse the steps. If the cover is not properly secured the TV will not come on.

I hope this helps.

The tv is plugged in but it won't come on. I've taken off the back and there doesn't appear to be anything wrong but it's still not coming on by remote or manually pressing the power button. What should I...

  • Replace the lamp on the TV and make sure the cover is on -
  • Step 1Turn off and unplug the RCA TV and wait at least 30 minutes for the old lamp to cool down. RCA's lamps can reach heats of 200 degrees Fahrenheit, so make sure you wait the allotted time before beginning.
  • Step 2Find the lamp's access door in the lower-right corner of the back of your RCA TV.
  • Step 3Unscrew the screw on the access door with a flathead screwdriver, then grasp the two tabs and pull the door gently away from the remainder of the TV. Keep track of the screw and don't let it roll away.
  • Step 4Use the screwdriver to loosen the two screws holding the lamp itself in position. You don't need to remove the screws, just loosen them.
  • Step 5Pull the lamp out of its housing firmly, taking care not to force it or damage the surrounding housing. Note the position of the lamp in the housing as you do so; the new lamp needs to match it perfectly.
  • Step 6Insert the replacement lamp into the housing, taking care to place it in the same position as the old lamp. Tighten the two screws on its frame to secure it into position.
  • Step 7Replace the access door and tighten the screw into position. The RCA TV won't turn on unless the door is secured.
  • Step 8Plug the TV in and turn it on. Wait 60 seconds, then tune to a channel to see if you can receive a signal.
  • Step 9Place the used lamp in the box which contained the new lamp, seal it and contact your local sanitation department for instructions on disposing of it safely. (Some RCA lamps hold small amounts of mercury, so you can't just throw them away. )

    Lost picture and sound

    You likely have a bad lamp. The symptom you describe matches a weak or old lamp. When you first turn on the TV, the lamp is cold and doesn't draw much power. But old lamps usually have clouded reflectors, so the reflector doesn't reflect the light, it converts it into heat. The bulb overheats, draws more current than allowed, the TV "recycles", green light flashing and then the process starts over. Replace the lamp, use and original Sony lamp as the aftermarket lamps are known troublemakers. Please be sure to rate this solution. Thanks!

    Replaced lamp and new wires, then changed back to old wires still nothing.

    Once you replaced the lamp did you reset the hours under the menu? If you do not do that some times the set believes it's in warning mode and prevents a potential implosion of the lamp which creates issues such as the set not turning on, staying on that long, or the lamp light still flashes.

    Let me know how that works out for you.

    Also, what "old wires" are you referring to?

    Lamp light

    Check the lamp switch that is located inside the door. Place the lamp in, and stick a flathead screwdriver in the slot (just make sure it moves) hold it there, and turn on the Tv. If that doesn't work check the new lamp, is it a generic lamp, if so they dont always work. If you still have your old orig lamp, take the old lamp out of that housing, and out the new lamp in the old housing. This should fix the problem.
