Blue dot and shadowing problem with panasonic PTL500U

My panny PTL500U is 2 1/2 years old. Recently I noticed a shadowing problem after I changed channels or paused a movie. Also, a spattering of tiny blue dot clusters has begun to appear on my screen. The number of dots keeps growing. What is going on? and how can I fix it?

    Similar problem - my PT-L500 is 4 years old and has developed a blue shadow in parts of the image. Recently a few blue dots have also appeared. Panasonic tech support not helpful. Bulb replacement has enhanced the problem. Suspect cleaning is required. Any suggestions?

SOURCE: panasonic pt52lcx65 problem are two blue dot

flavrlen, looks like a part of your TV needs re-attaching or replacement, depending on where the blue spot is there is a greater possibility that the EEPROM (IC) has been dettached, you may get this repaired or better off, replaced with a 128K, its just 8 bucks so no problem on that part. getting it in is the tricky part that will require professional physical repair.

if you want to you may contact panasonic to doublecheck,

here's a price list of the parts of your TV.

SOURCE: Green and Blue spots on screen

Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.

SOURCE: Three inch red dot appears on my Panasonic tv

Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and inspecting the lamp itself and the lens that it shine onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly.

SOURCE: Just bought my 65" panasonic. The picture has too

Whoa. You are so right. It is actually hundreds of thousands of tiny dots. You are not supposed to notice that, though unless you are sitting waaay too close to the screen or you have the worst cable connection ever. If you have checked all the connections and are sitting far enough away and it is still all dotty, then take that ****** right back and get a different one, no kidding.

Hello, I have a 55" Fujitsu Plasma Monitor that's


I have a Fujitsu scaleoview c19-1 bought it 10 years ago with a defect from Germany after it was maybe about 2 years old , the defect where only 2 supression coils that where bad soldered in factory so it was going on and off faultering that was the only problem and curiously all used capacitors are still all well have good capacity after all this years only the seperate powersupply on that monitor has have bad capacitors and 5 pcs replaced inside that unit i have beat it open and after replace all was again perfect. IF you have such a monitor with a separate power supply, beware its only a suggestion to help i have the capacitors in that powersupply replaced a 2 years back and i have no problems anymore but in most cases always powersupply capacitors can best replaced after 6 or 7 years even of a corsair power supply what is also very nessecary to do the Chinese black ones the heat dissipation is higher in power supply s and therefore if the size of the radial capacitors is made its to fit on replace then choose it 10 or 20 volts higher parts in place the newer capacitors are smaller take if possible 105 degrees parts or try an other powersupply to look for the screentrouble if thats not help and of control the graphics card and or powersupply of the computer.

No Right Front Speaker Output


Swap speakers over...check the balance isn't fully to the other channel...swap left/right phono cables over (if thats how your using it) other than that i would say is broke.
Easy way to check speaker cable/speaker... touch a small battery (like used in a remote) across speaker wires, you will hear and see the speaker cone move.

use good brand contact cleaner from radio shack or other electronics store and apply spray in the slider of defective channel and move each slider up and down many times.by the way check cabels which feed bad channel for a good condition and test these channel with the good cabel of good channel to confirm that the trouble in channel itself.after all if it is hopeless pass the mixer to service center to fix it.

When hooked up to digital cable box aspect ration changes from 4:3 to 16:9


I wonder, does it do this on all programs ? I notice the same thing on my cable box when some of the wide screen movies are shown. I know of no adjustment on a Sony that would cause this effect. Stargazer
