    My picture has no color. Its in b&w. The menu is in color, but everything else is not. I have a 27v514t that I am wondering if I could use parts from that one to fix my 27v530t. Also- the 514t was said to have no sound. I want to fix the 530t, but not sure if it has a seperate color graphics card that I can switch with from the 514t tv. I am at john27pa@yahoo.com

This problem could be a few things. first if you know how touse a volt metter go to the crt pcb on the end of the picture tube. Try to measer the voltage on the collector of the red drive transistor. If when the red color goes away and the voltage shoots way up past 150 or so volts then the red drive is disapearing from the video jungle ic or through one of the componets from it. If the voltage drops way low like less then 65 to 75 volts or less then theres a cold solder connection between the b+ feed resistor that suppys the b+ to the drive transistor the driver power supply sourse.. In an extremely rare case would the Picture tube be at fault but certainly could be. Good Luck OOps almost forgot it could als be a bad connection on the crt socket as well..

RCA model #f27648 reds missing from picture


It sounds to be a video output stage circuit fault. Check all the solder terminals at its CRT base card, including the solder terminals of the CRT base to the card. Re-solder all the suspected solder terminals by applying a little more fresh solder. Contact any service technician. Check the solder terminals of Red color output transisotor. If needy, replace it with a new one with same number printed on it. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience.

The fault is 'one colour predominant/absent screen'

Red, green and blue colours diveded on my TV


ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

Colours missing from tv


There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

I am trying to connect an akai dvd player to directv, please help


ruettab,

good day. to connect your any DVD player to any TV screen always remember this color code

from DVD back part:

yellow = video out

red/blue/green( in a row) = component video out ( this can only be used for screen with component video inputs)


Black = digital audio ( rarely use unless)
Red and white (in a row) = Audio output (left and right audio)


where to connect from TV screen.

Locate where A/V INPUTS (audio/video socket) from your TV screen, you can see it either at the BACK/SIDE or somtimes in FRONT of TV screen , having marked as "AV1"AV2"AV3' .

Once you found TV input, you must first have RCA cable (color code cable to connect player to screen) then connect the RCA cable at the back of your DVD player, simply follow color code

RCA yellow marked cable = DVD yellow socket
RCA RED and WHITE marked cable = DVD RED and white socket (second row for your player)

then connect the other end of the RCA cable to TV screen, first select which input where you gonna place the DVD player ( either AV1, Av2 or Av3 if do have multiple inputs)

once decided which INPUT to connect the player.
ex. if you select AV1 as input there would be 3socket on its row (yellow/red/white)

now connect the other end of RCA cable to the screen by following the same color code:

RCA yellow cable = TV screen A/V1 input yellow socket
RCA RED and White = TV screen A/V1 input red and white socket.

cheers,
mark

RCA CTC203 no red colour


Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
