Re: picture

You have a bad Capacitor. Look real good at the capacitors in the video circuits for signs of swelling or leakage. You may need a ESR meter if you cant find the faulty one by sight. An ESR meter will allow you to find bad caps in circuit.

My mitsubishi diamond series wd-62825 picture is too dark

There is something I remember and it may be the model you have---Mitsubishi can tell you or you can look for yourself----a few models made at about the time this set was made had 2 mirrors----one a tiny one that faces up and reflects the picture into the large rear mirror.

Dumb idea--the little mirror gets coated with dust and brightness drops up to 70%---

The safe and correct way to know is to remove the entire front screen with its frame---both mirrors (if yours has 2) will be easy to see.

The large mirror hangs at a angle and down so it never gets dirty--don't even think of touching it or using glass cleaner on it--any mark on it will show in the picture.

let me know if you want to remove screen unit to see if one mirror or two---a call to mitsubishi would answer that.

Philips magnavox 9P6040C104

i just found out why, turn on ur tv and remove back look directly into 3 lenses, if the picture is not nice and clear or looks snowy in all 3 u will not get good color or brightness. I removed my blue tube assembly and took it apart WHILE OUT OF TV. there is cooling fluid between lense and tube, this fluid over time will build a film on the face of the tube and get thick enough to block the tube from projecting picture. (MARK EDGES IT GOES BACK TO GETHERE THE SAME WAY IT CAME APART).Find some new fluid then carefully dissasemble and clean interior of lense, housing and tube thouroughly. Reassemble and fill with new fluid. Do not use old fluid it will be cloudy and snow globe effect. Only do 1 tube at a time this will allow u to realign cross manually as close as possible before u perform convergence. Leave the green for last that is the center and the red and blue are moved to match green. Also be sure to clean mirror and back of screen. Pete

Lines across the screen

the dark lines could be what is called hum bars these are caused by ground differences between cable and your AC ground. check to see if these lines appear using a dvd and removing the cable from the cable box. if the lines disappear then call the cable company and your electricain. in the mean time you can use a plug adaptor that is the 2 prong (ground less) until you can have the problem fixed. but don't use the adaptor as a fix, for your TV is a computer and needs proper grounds.

Dark Screen

The lamps in these normally last about 3000 hours (if your really lucky). The bulb will start to loose it brightness as a matter of due course at about the halfway mark. It maybe that you are running the unit in the non economy mode that they are fading faster then normal.
The sets have a reputation for not being good with lamps though.

Have a look at the lamp though, make sure it has been off for at least an hour to let it properly cool and check for dust that has settled on it. Also if you wipe the lamp, make sure it is with a dry cloth, or allow plenty of time for any moisture to completly dry before turning it on if you use a damp cloth.

Curved blue lines on screen.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.
