Re: Hitachi 27CX22B-501

You did not say whether it is bright, overdriven with retrace lines in it. I've have seen what I just described in Magnavox (common) and Zenith TVs. If you're unit looks like what I just described it could be one of the following problems. The fix for the Magnavox was a 10 ohm safety resistor in the green drive circuit (on CRT board). For the zenith it was the drive transistor on the main circuit board prior to the gun but after the video IC. In either case you will need an O-Scope to signal trace the video circuit to find the culprit. If this is within your expertise go for it, safely of course. If not, get a professional to do it.

Picture is greenish hue and cannot be changed from menu bar

The greenish hue cannot be adjusted from the menu. One has to do it from inside.First confirm by turning the color settings to zero using the remote. You should get a clean black and white image with no traces of any color ( inc: green ). If your TV is greenish , the green drive on the base of the picture tube has to be trimmed.
All you need is a screwdriver. There are dangerous voltages inside a TV, some as high as 27,000 volts !!!. Where the color adjustment has to be done there are voltages as high as 110 volts and 8000 volts.If you still want to make the adjustments yourself revert back for instructions

Theres no brightness setting in menu. it only has cc sleeptimer and exit. how do i change the brightness?

You can adjust the brightness control on your 19PR19 Philips Tv. For that you have to go to picture contol menu
Do it as follows

To adjust your TVs picture control, select a channel and follow these steps.

[1] Press the Menu Button on the remote control to display onscreen menu.
[2] Press Cursor up or Cursor Down button until the word Brightness is hilighted. For each press of Cursor Up or Cursor Down button you can go through Colour, Picture, Sharpness, Tint, Colour temp etc, depending on the adjustment you want to make.

Some channels on my tv are dark and tinted orange, I used the menu button to display the menue and scrolled down to picture but I did not know how to select picture.

Adjust colour control to zero, and check for a pure black/white picture. Adjust contrast and brightness control to minimum and check whether the picture goes completly off or a slight picture prevails. If the picture goes out when you turn down brightness control to 1/3 position, that is about 20 points, your TVs screen voltage is very low, and it can be adjustable. If the picture does not go out and more brightness prevails, screen voltage is high. If the screen voltage is high, there will be some fine lines across the screen at about an inch apart; on the whole screen from top to bottom.
Screen voltage adjustment is critical for the clarity of the picture. If it is low, no proper colour will be dispayed. If it is high, it is harmful to both picture tube and your eyes.
Never try to adjust it without proper knowledge about it. The screen control can be located alongwith the LOT [Line Output Transformer], of your tv. There will have two adjustable controls there, one is for Focus, and the other is for Screen. Both are interactive, that is adjusting one will effect an other.

I have a 50inch DLP Hitachi that is 3 and a half years old. I replaced the bulb about 5 months ago now the blacks are blueish and it has a greenish blotch on the screen. It also leaves an image on the...

Contrary to popular belief, any display product can have "Image Retention" and even "Burn-In". This is true for Plasma, LCD, LCOS, DLP, and CRT. I do not see a model number provided, but I would bet that you have an LCD rear projection TV rather than a DLP projection TV. If this is the case, the Blueish and Greenish blotches you are seeing on the screen are the result of UV light damage. UV light will move heavily damage the Blue panel, due it's short wave length. So, bad Blue or Green (absence or Blue) is typically the the first visual indicator of a problem. Replacing the Light Engine will resolve the problem.

The color is all mixed up

Go into the customer menu and select convergence--go to advanced(instructions will be on screen).

If it looks 3D and will not adjust you have a convergence circuit problem.


IT is a do it yourself fix-tells everything you need and how to do it.

If something else--try to describe it for me. I will attach photo of typical convergence problem for you here.

Purple tint

Do not put a colour television near a strong magnetic field. I have confirmed from several experts that this has the undesired effect of causing loss of colour
