Panasonic PT-51G44A TV

I have the above model and the picture keeps on getting darker and darker. What is the problem likely to be and how much would it cost to fix.? Would I be better off just buying a new TV? It is 8 years old and has been very good until now Any idea?

Thank-you
Jim

Picture on tv is dark panasonic mod pt47wx42


IT may be if the set has not been "serviced" in a while a cleaning issue. If picture got gradually darker try something easy first.

Unplug set and remove back cover.

Locate the three large black lens in set based on model number, use either a lens cloth or a paper towel with glass cleaner sprayed on it and clean all three lens.

The lens are the light source for your picture and if dusty the picture will be darker and duller looking than it should be.

If this is your problem it is a good idea to clean the lens at least one time a year.

Let me know if it works OR IF YOU HAVE QUESTIONS.

Brightness up all the way but pitchure keeps getting darker


There was a post on fixya in about December of 2007 detailing the replacement of capacitor C581 on the "D" board but w/o pics. I can't seem to locate that link now.

But... I just did the C581 fix on my set tonight. Here are pics

Hope this help.

====Disclaimer====
WARNING! There are high voltages inside the set even when unplugged dueto stored energy in some components. Do not attempt this yourselfunless you are experienced with this type of circuitry. I stronglysuggest that you get a professional repair person to do this work.

P.S.
33uF 160V capacitor from www.mouser.com is 82 cents plus shipping in quantity one.

Kids are disappointed we aren't going to upgrade to 52" LCD this week.

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

Panasonic Rear Projection TV -dark picture


Javabean,
First off I think you meant Panasonic PT-51G44A which is an AP815 chassis. That unit has an all to common failure of the capacitor at C581 on the D board which is a 33uf/160v cap. Replace it and I think that will solve the problem..
