I have a PT-47WX53. Had it for 7 years with no problems. I've been reading on the web that projection tvs need bulb replacements every few years. I've never replaced anything and still have a bright clear picture and there are no mentions in my manual about changing a bulb or lamp. Does this tv have a type of projection that never requires bulb or lamp replacement?

read your owner manual section troubleshooting or how to replace it.
God bless you
Rear-Projection TVs have a lamp, which picks up the picture and projects it on the TV screen. A burned-out or connected lamps are two of the most common problems for Rear-Projection TVs. First, you will want to confirm the bulb is still good. If the bulb is bad then then replace it immediately. Second consult your user manual and verify the lamp and lamp cover are installed properly. Most Rear-Projection TVs have warning light which notify you when there are lamp problems. Again consult the user's manual to see what each light means.

Replace lamp. Lamps go out. Don't no why. That is the downfall of these sets . The lamp life can not be predicted.

Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

PT-50LD54 is an LCD rear projection TV with a consumable bulb that wears out normally after 2-5 years of use.

Most likely you need a bulb. That is first step in any troubleshooting for that tv. Check out Panasonic Gallery to identify lamp and replacement bulb.

Changing bulb involves removing the lamp assembly and replacing the bulb in the lamp assembly. Like doing a puzzle. Requires philips screwdriver, pliers and patience. Don't have jam on your fingers when you do it.

Most likely problem is bulb failure. Replacing the bulb is first step in any LCD rear Projection troubleshooting.

PT-61LCZ70 has a special "Super Dooper" long life lamp that costs a ton to replace. US users have 5 year warranty on the lamp assembly. Canada users can whistle for help from Panasonic Canada. There is no replacement bulb available, only expensive lamp assembly.

TV has to be completely taken apart to change the lamp. Panasonic service information is 12+ pages for lamp change instruction.

Check Panasonic Lamp Gallery for an image of this lamp assembly.

I have a PT-50LCX63 unit. After 5 years and 4 bulbs, a "reset lamp" warning showed up every time I turned on the tv. I have to say that after a few weeks, the message ceased on its own. I don't know if all models eventually reset or turn off, but I could not find any other information on the direct way of resetting. I find the warning a waste of time since the bulbs are good for 10 -14 months. Sadly I missed the class action suit that dealt with the premature lamp failures. I am looking for a new tv at this point. Bulbs have cost me $1200.00 since I bought it. The warning is supposed to allow you the option of replacing the lamp before it fails, Ha! what a joke...Thanks for reading.

At first i was thinking the ballast had gone bad but after reading a few other post i think it would be best to call pannasonic..
others forums read:
ballast had gone bad. Panasonic no longer makes these ballasts so mine needed to be rebuilt at the tune of $400.00.

With the ballast in place still nothing so now they claim that they need to order a "kit" from Panasonic which basically is all the components of my tv.

Camaroguy: This exact problem happened to us about 8 months ago. A board had to be replaced at a cost of $500. Yesterday, the convergence has gone on the set. You get a blue and yellow shadow on the picture. From what I have been reading, this has happened on a few TVs and it will cost another $500 or so. We refuse to pour more money down the drain so we just went out and bought a new plasma (RCA) for half what it cost us for the Panasonic 4 years ago. We have never had a problem with RCA in the past (two tvs for 20 years a piece).

ya thats the standard line from the twenty somethings at the stores now suddenly 15 years of crt tvs all magically have bulbs like a dlp tv these are the same people that they interview on the street and ask who the president of the united states is your tv was originally made by samsung if you read the sticker on the back no user serviceable parts... its kinda like the tag on a pillow any way there is circuit board with two parts on an aluminum heatsink unplug the tv of course take off the back panel and uplug the red plug from the circuit board with the two black modules labeled stk392-040 this whole board can be replaced for 70 dollars parts store dot com
