It is not as simple to replace as a bulb. This is a picture tube, and for a novice, no play it safe and have a tech have a look first. Just because the picture tube does not light up, does not mean the tube is bad. There could be several things in the solid state circuits that could cause this problem. Good Luck

New member here. I have a 62" DLP Mitsubishi model #WD6252. I've already replaced my lamp AND ballast and continue to have the solid red lamp status indicator. I've made sure the connection from th

Your color wheel is failing or has failed. the red light ONLY means the lamp cannot light or was forced to shut down. it means nothing about the lamp or ballast specifically.

If your color wheel isnt spinning up correctly or you have a stuck fan somewhere, the lamp will be shut down immediately upon startup.

Id check to see if the color wheel is stuck or if its getting stuck.

The color on my tv is turning green. It's not totally green but it's becoming green. No matter how I adjust the colors it remains the same with too much green. You can't see the true colors...

It is very common for the color of the lamp to change as it nears the end of it's life. Depending on the bulb itself you may see yellow, green, or blue shifts (I have even seen red/orange). This is due to the diminishing output of the bulb and while you can make some adjustment you will eventually hit the point of failure. The bulb could in fact last several more weeks or even months depending on your use and environment. It is probably a good time to start searching for a replacement now so you can replace it as soon as it dies or just replace it now if the color is too bad to be worthwhile.

Hello mrsb422,

This sounds like a convergence problem and it is a little more complex then just a lamp. You will have to replace not only the convergence amplifiers but also the biasing resistors. This will require de-soldering and soldering of of components and there is a chance of damaging the circuit board is you are not careful. So I suggest that you have a TV repair technician examine and repair this set.

I hope this helps,

Thank you,

My RCA is screeching

To install the color wheel, turn off and unplug the tv, take off the lower back casing (17 star type screws), remove the lamp door, remove the lower back casing. Look just left of the lamp you will see 3 smaller star type screws near a small circuit board (which is on the color wheel), remove those screws unplug cable from color wheel, unplug other end of 2nd cable from tv circuit board (just to the upper left nearest to the color wheel.

All you have to do is install the color wheel, plug in both cables, put the back on and place the lamp door back in its position, the lamp door pushes in a lillte blue lever which allows the lamp bulb to light up.

I'm in the process of doing the same myself on my RCA same model. Where did you buy the color wheel from?

Sony kf-50XBR800 tv turns itself on and off

I just purchased a replacement lamp off ebay and the TV is working fine now. Color looks better too (which I guess I should have expected). Search for "REPLACEMENT LAMP SONY XL-2100U" on eBay and look for seller "niosales". I paid $129 out the door. Their are other auctions for this lamp you can check out. Make sure you look at lamps that include the entire lamp housing, not just the bulb.

How long does a lamp/bulb of a Toshiba DLP 46HM95 46 in last?

Your bulb may be blowing because of airflow issues or power cycling issues, first does your outlet get switched off at any point in time? if so you may be killing the bulb before it cools, if you turn the set on/off alot and or restart it after off quickly this could lead to permature bulb failure, if the original lamp was not replaced with a proper lamp to match the ballast it could blow the bulb. If your tv is too near a heat vent or the airflow thru the set is not adequate it could blow the bulb.
