20 Most Recent Sony KV-27V22 TV Questions & Answers

Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/

You will need the remote that comes with the TV (Sony). There is a button called "Display". Hit the "Display" switch on the remote to go through selections - until "Display Off" is display on the TV screen. Then wait about 3 seconds, and on screen display will go away.

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

Look for bad soldered joints in the vert output and resolder them.

the variation from higher channels from lower channels, few things changes eg frequency, voltage, and current.
take your tv to a w/shop and have the following
tunner voltage pulse variation on a avo meter has you change channels. if the difference of voltage is not unform when you are changing from to channel then you should change the control ic on the rf stage or check the capacitors a round the rf ic for variations in value.

Wash well with running water and seek medical attention.

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.

Hello,
Its behavior is not normal. Have it repaired. Fumes are hazardous to your health especially to the little one's health. Think of a fire hazard too. As the adage says :No fumes without fire.

Hope you decide to be rid of the bomb or have it repaired.

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.

i have forgotten my parental control pin after five times pin then it has blocked how to unblock it. which codes should i use to unblock

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

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.

You have a failure in the convergence circuit. There's a circuit board ( the convergence board) which has 3 IC'c on it that drive yokes on each of the picture tubes red-green- blue. You probably lost power to these IC's or one or more may have opened up. Sometimes poor solder joints on these IC's will develop causing loss of convergence. Hope this gives you an idea as to where you problem is. Stargazer

Does this happen with TV signal only, or with other inputs as well?

check horizontal drive tramformer for intermitance is common problem some time blows horiz transistor to or vertical IC intermintence to

sweetkiss, if it works through the dvd player and not on cable/satellite box then the tuner is bad, if you have any type of cable/satellite box try running A/V cables out of the box to video input on the back of the tv and switch the tv to that video input, ie; vid 1, vid 2 etc. (your using one of those inputs for the dvd) this will give you your picture back, you can of course also replace the tuner in the set, good luck, BMW Rider

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

It is likely the HOT (horizontal output transistor) and a couple of associated capacitors.
common failure.
the HOT is around 8.00 and some for the caps.
but almost no tv person works for less than 100. and provides a warranty. so you can expect 150. at least for a bill.

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.
