I had an electrician come over. He pulled out the bulb that was dead (for me it was the color that was flashing before it would turn off) and now I have a blue and green TV with no red. He said that the only way to fix it is to replace the red lamp with a new one.

After cleaning the lenses on my 60P8342a tv and turning the color buttons in the back my tv is shutting off and on and I have a flashing power button, no pic or sound at times


How long was it back befor you turned on this potentiometers ?

Dust and more can be come into the potentiometers of a crt (cathode ray tube) projetion tv in the years that its old it is not strange.
Ist an older kind of model of projection tv.

Treat them with contact spray , also not only red the r g b potentiometers but all the potentiometers that are parts of the convergention panel. and adjust them on a screen with the base saturation of color to zero so you adjust a good gray tray with a balans without a red brown or green or blue surplus so that you have white gray black in balance if you have adjusted , tur back on the basic color saturation to your prefered level.

Chances are pretty good that the weather will be fine.
To see some brown spots on the board and replace any carbon composite resistors for carbon or metal film resistors in the print because of high tolerance over this kind of resistance.

Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

How do you know if you need to replace the fluid? can you show me some pics of good red green blue color or some bad colors


If the glycol is bad, there is a easy way to tell:

Remove the back cover and with the set on use a small mirror--put it over each of the three Lens--red will never be bad this way.

What you want to see is a green picture on the green tube and a blue picture on the blue tube.

If instead of a picture either the green or blue look like a floodlight with no picture--the glycol is contaminated.

What happens is bacteria grows in the blue or green glycol--never the red--for some reason it does not like the red color.

Usually the blue will be the one first affected---picture will have a yellowish look over most or all of the screen (turn the color all the way down and stand back at least 10 feet and look at it,

Changing Glycol involves some important things---this stuff is like antifreeze bit ten times more toxic.

If you find yellow and want to know what is really involved respond to this posting and I will assist you.

the lenses are accessable by removing lower back of unit,clean them with a damp paper towel-wipe them off with a dry one.put back back on unit.
screen/focas controls are in front of unit.remove speaker grill remove black cover using phillips screwdriver.you will see 2 sets of controls.one row is focas.one row is screen controls.red,green,blue.turn each focas control slowly to get the clearest picture for each color.screen controls are touchy(if you turn then too high unit will shut off)if the black and white picture was good i would not adjust screen controls.if it was bad turn blue and green screens down all the way.picture is now red turn green up until it turns yellow then turn blue up until it turns white

Hi i need your help please


When you adjsuted for the blue you were actually adjusting the voltages to the CRTs (lamps) which in turn shut them down. You will need to turn each one of the dials up agin untill your tubes stay lit, then the coolant in the green and blue CRTs will need to be changed as the green evidently is contaminated thereby making the blue dominant. But when you turn down the G2 controls your actually turning down the High voltage to the picture tubes thats why they dropped out on you.

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Red & green lamps shutting off leaving a blue screen


Could you show a picture of the distended cover you mentioned?

 

Were the light blue lines you were referring to, diagonal, or truly horizontal?

No Picture


Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
