Hi Lizzette,
I am afraid your problem is a little technical. Well if you know something about lcd tv technicals, the problem seems to be the T Con board and/or its connectors. Check the ribbon cables and connectors, clean them properly and and start the tv.If it is not possible or it does not work, please consult someone qualified to handle your set. Good luck.

Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Image is bright but there is a slight issue - on the left hand side a purple line displays vertically. Anybody knows why is this fault appeared and how could it be solved.


There is three LCD in the projector red, green and blue. If green LCD make any fault mean line or dot or dots then screen show these line or dot in purple color:
If line is very straight and sharp edges then green LCD is faulty and need to be replaced.
If line is not straight and faded edges then some thing in LCD block so your projector need service

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....


Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

My phillips model 60pp920217f has a horrible picture...no green to the color


The green CRT coolant has congealed thats whats giving you the green halos. Change the coolant in the green and blue and your set will be fine. red is never affected so the red coolant should be fine.

Philips Flat Screen Green Lines


The LCD Panel is defective. You will need to replace the LCD Panel. It will probably be cheaper to replace the monitor since the LCD Panel may exceed the monitor cost.

Single lines of single color (red,green, blue) are LCD panel failures.

1 or 2 lines of single color are LCD Panel failures.

Multple color lines could be anything so in this case you start by checking the power circuit.
