Blank Picture, Sound OK on Sony TV

most likely it needs repiars, (replacement of capacitors in the power-supply.)primary and secondary side.
Or loose conections (dry joints)

try to adjust the screen. it is located behind the CRT board.(CRT board is the board that attached to the picture tube) you will find a black knob which label screen adjust it by turning the knob.

Sony Trinitron TV. Worked well last evening. Now picture won't go on. When power is turned on, standby/timer red light flashes, but picture or sound does not work.

Forward voltage/current problem....needs a new board....You might try unplugging it for a few hours...If the TV starts you will need to leave it on until it gets repaired or replaced.

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

dear, you can check that transformers out put before connecting to a tv. also when its connected to a tv.
get a avo meter and connect in series with a tv.
observe the current on the intial switch on and when the picture goes. if you notice that current on intial switching is high and then it starts going lower and lower, then change the transformer.
but if the current starts going up from the intial current then check the power supply components of the tv.
thanks for asking fixya.

Hallo, IC MCZ3001D is damage. Cost 30 Euro. Greatings from Germany

Solder any / bad connects horiz,vert and power supply then
try again....................T.

Please rate this solution.........................

Hello, maybe there is a contact error in power supply or the deflection stage. If the resoldering does not help- here are some possible solutions: remedy Replace flyback location LP04. Entered for KV32S22 /SONY (Chassis) remedy 2 Replace IC351, Q602, Q601 (2SC4834M), R607 (1R/0.5W), R622 (10R), IC641 (SI3090CA) and Q502 (2SC5148). remedy 3 Replace tuner. remedy 4 Replace R607, Q502 and IC601. Entered for KV32S22 /SONY (Chassis) remedy 5 Replace regulator IC, R607, check C609, C610 (0.68pF) and C613 (0.0022pF/500V). remedy 6 Replace horizontal output transistor (2SC5148), IC601 (MX0841) and R607 (0.1R). remedy 7 Replace IC1701 and IC601. remedy 8 Replace Q501 (2SC5148), R607 and resolder horizontal driver transformer. remedy 9 Check and replace horizontal output transistor Q502 (2SC5148) and IC601 (MXD8411AB-F). remedy 10 Replace shorted R607. Also check T501 and Q501 for dry joints. remedy 11 Replace C608. remedy 12 Replace Q602 and D648. remedy 13 Replace Q502, Q601, Q602 and R602. Entered for KV32S22 /SONY (Chassis) remedy 14 Replace D626 (6.2V). remedy 15 Replace IC801 and R607. remedy 16 Replace horizontal output transistor and the associated damping capacitor. Check flyback transformer and SMD microprocessor as well. remedy 17 Replace R639 (4.7R/0.250W) located on G board in standby power circuit. remedy 18 Replace D600. remedy 19 Replace C502 (0.47uF/50V). remedy 20 Check D655(1N4937), D657 (1S1834) and Q601 (2SC4423). remedy 21 Check D606 for leakage. remedy 22 Check yoke between vertical and horizontal windings for S/C. remedy 23 Replace Q601 (2SC4834MNP), R607 (0.1R) and C517 (2.2uF/250V). remedy 24 Replace R611.

Protection circuit fault kicks in. No vertical Deflection (V STOP),B+ over voltage protection (OVP), This is about a $150 -$200 to fix.
