Sony KV-27V22 TV Questions & Answers
I have a ten year
most likely it needs repiars, (replacement of capacitors in the power-supply.)primary and secondary side.
Or loose conections (dry joints)
Burnt electronic smell even hours after tv turned off
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.
No picture, sound works on Sony TV KV-27V22.
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 KV-27V22 scrambled picture and loud buzzing audio
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.

check horizontal drive tramformer for intermitance is common problem some time blows horiz transistor to or vertical IC intermintence to
Sony Trinitron color TV model no. kv-27v22
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.
Sound no picture on cable
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
Sony Trinitron: No 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.

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

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

Have you tried adjusting the red screen control located inside the front of the set? Usually behind the speaker grill. It is part of whatis called the control focus/screen block. There are 6
controls on this assembly. Be extremely careful
high voltage is present. If you turn the red screen control and no red is seen onthe red gun , there are two possibilities. A) bad picture tube
B)open filament connection on crt board.

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,

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.
