If the bulb is burned out will that cause no sound

It's time to change the projection bulb. You need to go to Amazon.com and search for tv bulb with model number of your TV. Now the tricky part is to try to get the bulb with the longest warranty. Don't get one with a 30 day cause the bulb may go bad by then. Get one with at least 120 days. As well read the reviews and make sure the other customers are happy.



Changing the bulb is easy and only requires a Philips screwdriver. There are YouTube videos to show you how. But these bulbs are very special and blow easily, so get one with a long warranty. And don't get a spare, cause by the time you need it, the warranty period will be up.

With a DLP TV, getting a darker picture means it is time to change the bulb.

Sounds like lamp again-- dark pic. Get quality lamp, need 4 inch space all around TV for cooling. Maybe cleanout dust inside.

This sure sounds like a bad lamp. If it is over 3 years old change it.
Also, listen for loud buzzing sounds that may indicate a bad color wheel.
But this definitely sounds like a lamp that is about to go bad.

yes, remove the lamp assembly and inspect for cloudy damage or glass fragments, if yes,, replace

there is a lamp to generate sound bad because this is a short-circuit it is recommended that a technical review

Hello
And greetings from York PA!
Ok I have read what you were saying about your TV and after much consideration I dont think its the bulb because a bulb does not get better as it warms up! (most bulbs that are bad get worse as the TV warms up!) But capaciters do act this way when they go bad (stable when they warm up!) so I would have to say the control circut has one or more bad capiciters on it and will need replaced!
I hope this helps greatly!
Please rate this answer!
thank you!

Yes, the lamp will gradually get darker as it nears it's end. The rolling lines sounds more like the set is on a local channel for the cable hook up. If your local area has a channel 3 or 4 live terestrial broadcast simply tune the cable box output to the other one, the same for the tv.
If this is cable/local broadcast issue it will go away in Febuary when the NTSC broadcast ends.

Sounds like you need to replace your lamp. The lamp number for this panasonic TV is TY-LA1001. Lamps run anywhere from $120-$250.

The tv has a room light sensor,
shine a bright light at it , does picture get brighter?
other wise when it is cool open the bulb door , is it coated or blackened, Don't touch bulb at all.

and a heavy covering of dust on internal mirrors will cause the same effect.
you will need help to clean it.
