Question about Sony KV-27S20 27" TV

2 Answers

How to find pins for the EHT and FBT.

Thanks for the responses. I have done some electrical soldering but have never had my 27' Sony apart. Where would I find the pins for the EHT and FBT? They are probably on the board but where. I don't have a schematic unless there is one inside the TV. Any extra info would be appreciated. I don't want to bring it in unless I have to. Do I need to purchase a service manual? The actual model is a KV-27V20.

Franko, The FBT and the EHT are one and the same. It is a big block, generally found at the rt side of the PCB board. It has two leads - One Red going to the Picture Tube, and another Black going to the Small PCB on the Neck of the Picture Tube. will also have 2 controls - Screen and Focus. Just slide the PCB out ( Mind you, remember to unplug your set, and wait for an hour or so to enable the High Voltages to discharge, before you you try any soldering.) Also, remember to wear Rubber soled footwear! After sliding the PCB out, tilt it partially, and solder the pins which are part of the FBT. Also try resoldering the Hor. Output Transistor Terminals (Generally mentioned as Q801 in most SONY TVs) Slide the PCB back in, and close trhe set. Try switching it ON again.

Franko, If your sure about troubleshooting HI VOLTAGE then disconnect the horizontal output transistor first. Is it shorted? if it is get the fly and the transistor. But I wouldnt start it up with out a variac transformer. For the parts, go to http://www.partstore.com amd see what the parts cost or get the tele # and call them. BE CAREFULL. Good Luck

I'm having problems with the picture. It takes a long time for the picture to come up. Sometimes it will come on, go off, etc.


after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then 1 of the indication is ....it takes few mins for picture to appear...& in some TVs it will come on & goes off (your case)........so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching TV ) ----------iam from bangalore (09986222774, sathyavijayasarathibabu@ymail.com) ----- here EHT's price will be around US $ 10 & for my customers (in bangalore) i will take another US $ 12 as sevice charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact TV service engineer or sony service centre ------- because they are highly experienced & can fix this component very easily.....

My tv will turn on and stay on for about 2 minutes, then it will turn off. Any suggestions if this could be repaired?


Tv have picture and sound within that 2 minutes?Yes,than tv have coldsolder joints some where just resolder the video board connections pins hole socket of the video board connected to the tv CRT-tv tube.The FBT resolder it too.The big black block of plastic witth a red wire with a cap hook up to the CRT-tv tube.U just require a soldering iron and a roll of solders and know how to do basic soldering?Most of the times just require resoldering for FBT-for stronger highvoltage output for the Flyback transformer.The video board CRT-tv tube sockets pins in the connected them both,will solved the problems.

KVM27FV15 won't turn on and just blink on the standby light. What is wrong with it and can still be fix or end up on the dump? I'm pretty handy on things and did soldering before.


Resolder the FBT,that the flyback transformer.The big black block of plastic with a red wire with black cap hook to the CRT(tv tube).Replaced the transistor outside of the solid steel wall of the FBT,that transistor help the FBT have stable high voltage.

Standby light


This problems is cause by FBT-Flyback tranformer the big black block of plastic with a red wire with a cap hook to the CRT(tv tube) and the "H" horizonal transistor left side of the steal plate cage of the big black block of FBT.U have soldering tool,and solders?Resolders the FBT,and "H" horizontal transistor will help to stop this problems,if those parts are still goods,not dying.Or might help just leave the tv on 4 or 5 hours,the heat of the tv could heal the cold solders itself.

Light blinks four times, screen doesn't turn on


PER TO WHAT SONY HAS TO SAY IT IS A VERTICAL PROBLEM. SOME TIMES TH EIC JUST NEEDS TO BE SOLDERED. IT IS ON A SMALL HEAT SINK IC545. IF IT IS NOT SOLDERED GOOD THE YOU PROBABLY NEED TO REPLACE IT.
There are three defects can cause the Standby/Timer LED to flash in groups of four:
1) +13V and/or –13V from FBT/pins 9 and 7 respectively are missing on Vertical Drive IC545.
2) Vertical Drive IC545 is defective (no reference pulses output on IC545/pin 3 to IC001/pin 78).DON...

TV Black-out


a tap on the side tells me that it's a solder connection broken loose, most likely in the horizontal section. if you have experience with electronic soldering, you can fix it, otherwise take it to somebody that can fix it. thermal expansion and contraction(from turning the set on and off) eventually produces metal fatigue in solder connections, and the connection breaks loose, just enough that it sometimes works, and sometimes doesn't.
