The problem with your TV trinitron wega is at the color adjustment section. It is located at the color board mounted at the back of the picture tube. There are variable resistors that represents the color pattern in the picture tube. Adjust the red color to low level to lower the red color.
U Know basic soldering,have soldering tools and solders?Take ur tv back cover off,resolders the video board the connect to the CRT(tv tube).Also,resolders the CRT yoke connection to the main board,the connection have GREEN,YELLOW,BLUE,RED to one connection's plug to the main board.You do the above ur chances to get colors back are 80-90%.U can tries to reset the tv back to factory setting,by unplug,replug it an hour later,this method 50/50 to get the colors back.
the problem is at the crt base .there r three red,blue n green o/put.verify if there is dry in the soldering n check the red cathode voltage it must b around 150 .if not then check the resistor that feeds the red o/put.it could b 12 to 15k.
all crt have 3 driver color red blue n green,whenever one driver not working the color changes.that wat happened to ur tv
now i do not know wat model u have.the drivers may b transistors or now its ic that r being used like tda 6103q.best of luck
You either have a bad CRT or a Shorted Red Output IC/Transistor. One other possibility is if
someone turned the Screen Control down if it is accessible from the back of the set.
Hope this helps,
Sounds like the red picture tube could be shorting internally which would cause the "all red" condition. In which case you'd have to replace the red tube. Are there horizontal (slightly slanted) lines through the picture as well when this is happening and a very very bright screen? If so it's most likely the tube.
HI ,USE A PATTERN GENERATAR DOT OR LINES TYPE AND USE THE CONVERGANCE RINGS BEHIND THE YOKE OF THE SET ,THERE ARE THERE RINGS FOR EACH COLOUR RED GREEN AND RED .SLIGHTLY MOVE THE RINGS AND U CAN SE EIN THE PATTREN THE COCLOUS WHICH IS FRINGES EACH BY EACH U ADJUST ALL THERE RINGS FOR PERFECTION , FIRST LET THE SET BE SWITCHED ON FOR 1 HOUR AND THEN DO THE ADJUSTMENT. THANSKS
have JVC AV-32F702 TV. It's picture color is very red. unable to adjust colors through menu. Channel numbers are also in red now instead of normal green. any suggestion?
please check red color cathode circuit
1 check red output from ic to red cathode ckt
2 check voltage on r output ckt& ic or tr.
3 check loose contact in red cathode ckt
4 check crt base for loose.
5 loose connector
6 chroma ic
the problem is in your color circuit and power supply make checks in those areas check the power supply regulator, diodes, cap ,and resistors.in the color circuit replace your color ic.then you can do resoldering of the components in the those same circuit,this will contain your problem good luck.
