From voltage given by you states that rgb output voltage is more than normal & drive is only .2 volt which is abnormal means signal is not coming from chroma ic. so check for loose connection in chroma ic or connector loose. same time your drive voltage abnormal is due to signal not coming so no voltage drop & more voltage. also check for crt base loose. hope this will help. good luck.

Sony wega-ha21m80 problem no picture reterc line ok sound

I THINK YOU MEAN RETRACE LINE. if your tv has retrace line the video amp circuit should be checked its a transistor or in other cases its a IC replace either of them.if its an transistor on circuit voltage measurements shoutld be 2.4 volts from the emitter amd 2.8 volts on the base.can also be a faulty inductor..good luck.if you are not a tech have a tech repair your tv.

There are re-trace lines across the CRT.

check the G2 ,if to high retrace lines wil be vissable.If ok check the RGB,12V on picturetube panel.
Are the lines in one collor then check the circuit of theat collor

Sony KD-36XS955 36 inch wega televison has yellow caste, cannot adjust to get any blue color. Has same problem on both cable and Directv. Unit is about 3 years old.

It is one of two issues, the blue video driver is defective, or the blue gun in the picture tube is open. This will need a tv tech to varify the problem and suggest a course of action.

ALL the next is with the tv unplugged (NO NO power)
  • resold the jungle (video processor) all around
  • following the horizontal drive pulse path and arriving to the horizontal area just after the horizontal transformer and in the base of the horizontal DRIVER there is a electrolytic capacitor (if this chassis uses this one,) Change it (maybe is dry)
  • solder all components i just told you in the last step. horizontal driver, transformer, etc
  • remember:
  • if a transistor is blowing with no reason (there is a reason: the collector receives 130 volts but cannot hold it forever, It has to be in some place. if the switching pulse doesn't arrive to it the transistor throws this 130 volts and burning itself. i hope it is help full.

To repair a tv set

If it has white out with screen retrace lines it means that the 130-200 volt line is missing from the flyback transformer to the neck crt board. begin by checking if the .68ohm to 1ohm fusible resistor is open circuit.if it is then you either have a defective rgb drive chip, or in most sets a shorted drive transistor. a defective gun in the tube can also take out the fusible but unlikely.

No picture

Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at

Tv repair

you can try to check if the problem is near flyback transformer
you ha to disconnect the power cord , open tv and locate power
transistor for generate high voltage it is near the big four connector 
cable the transistore you have to dissolder from board and check
with multimeter if it is shorted or not in this way base to collector
junction about 500 or more base emitter the same  collector to emittor open - delfo

Plasma tv


Check the contrast settings
If you are a Technician than just check the video supply from 150 to 200 volts at all three RGB Cathodes in most of cases there would be dry soldering in others it could be due to failure of supply resistance check base biasing voltages if u can provide more information then I could pin point the fault

Good Luck
