No picture, sound works on Sony TV KV-27V22.

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

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.

have the cable company come out and check there cable box and picture.

HI,YOUR PROBLEM IS ON THE FLYBACK TRANSFORMER OF YOUR TV. YOU MUST REPLACE THIS BUT BE VERY CAREFUL REMOVING THE FLYBACK.

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

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

Try hard reset = leave unplugged from AC for a long time.......T.

Hello, there can be a contact problem in power supply, deflection or RGB stage. Please ask the tech to repair it for you. Best regards, Arpi

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.

The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

Locate vertical output IC = solder all pins = two off-set rows,
then try again................part location IC301 , or 401 ?

2) possible bad CRT = turn up screen voltage slightly = did pix pop back on ?..................................T.
