    I tore into my Panasonic PT-47WX42 and looked at the tubes. I shined a light directly into them and they look very clear...no haze or crystals. Are we certain the coolant needs changed? I purchased a coolant kit but want to make sure first. Also, Has any one changed the coolant in this model? Need to know how to get the speaker grill off.

    I opened up my Panasonic PT-47WX42 to look at the tubes. I shined a light into them and the look very clear...no haze at all. Are we sure the coolant is the problem here? Just want to make sure before I use the coolant kit I bought. Also, can someone tell me how to get the speaker grill off?

Try changing the coolant in the CRTs this is usually the cause when a projection unit gets dim and hard to focus.

Why does my Panasonic 52 inch rear projection TV make a clicking noise with no picture after turning on the power? I replaced the lamp a year ago with no issues.


You might want to look at the lamp again to see it is intact and not shattered----2,000 hours or 2 years is normal life for a OEM lamp but a generic or cheaper version lasts about a year and picture is usually not as bright as with the original ones.

Only see 3/4 of picture on my panasonic 47inch projection tv


If the remaining picture looks bright as normal then it sounds like the Horiz deflection amp has a failed component. Most likely a blown transistor or burned emitter resistor or both. Not to expensive to have repaired.

My Panasonic HDTV Projection Monitor/TV has lost it's brightness. It still has a picture but dark.


THe coolant in the CRTs most likely needs to be replaced. this is a very common problem in Phillips and magnavox rear projection TVs.
