I find the colour contrast is very dark could you send me ideal colour settings for perfect clarity thanks


Hello
Adjust the contrast to 55 to 70%; brightness to 45 to 55% and colour to your viewing taste. Now the brightness will be very low I thinks. Advance the brightness and contrast after setiing the colour to Zero. Adjust for a well defined B/W picture first. The advance the coulour. Take reference of the face colour of a news reader at studio. The picture will be perfect. OK.

My KP-51HW40 clicks off after running for a period. The red power light blinks when it goes off but screen stays dark. When TV is shut off for a while it restarts and runs fine. The "On"...


Hi,
KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down.
This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color.
Solution for your tv problem is Screen Voltage adjustment that can be done easily if you are handy with electronics stuff repair.
Let me know your expertise level to guide you more and if you feel unconformable by tv repair then local tv repairman will help you to adjust white balance in tv.
Hope these info will help you.
Let me know if you have additional questions.
Thanks.

Lost red


Hello
Your Tvs red output has gone out. It may be due to a driver transistor probelm or an Ic problem. If your tv circuit uses transistors to drive red, green and blue; red drive transistor has opened. If it uses Ic in video output stage, Ic is damaged.
Just check the voltages of the cathodes of other two, that is , take the voltage of green and blue cathode. Voltage at the red cathode must be very near to the same as the other two. In your case, voltage at the red cathode may be high, due to the trouble of the above said transistor.
You haven't stated about the picture condition. The above said will be correct, if the picture is correct, eventhough it has no proper colour balance. If picture is not there, the falult may be in the chroma section of your tv.

My tv is showing to much red on screen


I don't have a lot to go on. If this is an older rear projection, this usually means the face of the green picture tube is dark (the picture goes purple-red) or there is too much red tube(excessive drive). This is a technical adjustment as it is in an area containing hazardous voltages. Adjustments will be a stop gap as rear projection TVs are all past their usable life span (About 8 years + with moderate use)

Problem with a colour display on Hisense tv


If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

Too much red in picture unable to get it out


The most common cause is the emission of the CRT electron guns are decreasing. They are going out of range and of proper balance in relation to each other for the AKG (Automatic Cathode [K] Gain) circuits in the CRT drive circuits to compensate for proper colour balance and colour tracking.

A less frequent cause are components going defective in the CRT bias and drive circuits.

I would be considering a new TV set with this type of fault condition. The cost of servicing this would be expensive.

No red


Losing one colour probably means failure of electronic components related to the particular colour. It is unlikely adjusting the red settings will fix the problem. Even if it did, the colour balance needs specialist equipment to properly set up.
