After lamp replacement

I replaced the lamp in tv it restarted fine picture is great. NOW when I turn off the tv it begins to start up but shuts off and the two red lights indicating lamp failure are on. If I slid out the lamp and then push it back in the tv starts up fine. I have to do this everytime I shut it off. Is there a reset? or what can I do?

Re: after lamp replacement

Optoma RD50/RD65 uses E23 5Kv precharge lamp. E23h lamps from ebay are 15Kv precharge. The letter h from E23h indicates High precharge voltage, 15Kv. Check out my other post here:

Insist on E23 with 5Kv precharge or it's not going to work on Optoma RD50/RD65. I ought to know, I bought 2 lamps E23h on ebay to find out the truth.

Re: after lamp replacement

I just replaced my lamp. TV seems to be working fine, but I kept on getting the message saying time to change lamp. I went to the service menu using Menu 6-1-9 Menu, and try to reset the lamp life, but it's not letting me do anything so every time i turn on my TV, I am getting that error message.

Sounds like the plug is not making a good connection needs to be seated better.

See Here:

as well as in your manual. Sometimes the lamp must be reseated
by removing it and reinstalling it with great care making certain
the door and all the gaps are closed tight.

If the lamp replacement or reinstallation does not solve the
problem you will likely need a service tech to look at the tv
as there are few user serviceable items for Plasma sets. Most
of the repairs are done by computer connection that downloads
the error messages and interprets what went wrong.

Hope this helps.

Need Help big screen turns on thens goes off

a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.

Tv turns off

Its the lamp that needs replacing. It will run for a couple of seconds and then it would dim or turn off.

I have the same TV and just replaced the same lampTY-LA1000.
You have to reset the clock that times the lamp.Hold down the volume button(first you turn on the TV) while holding down the PiP button or the swap Button on the remote. that fixed mine.
