Question about Sony KV-27S45 27" TV

4 Answers

Clicks - but no picture!

My 1998 Sony Trinitron KV-27S45 has worked flawlessly for years, and has been in the same place since I brought it home from the store. I usually use this as my alarm clock, because it's so reliable. Today, it just clicked - and no picture or sound. Everytime I try to turn it on - remote or manually - it clicks like it WANTS to turn on, but my little red light on the front just keeps flashing four times, and repeats. Does anyone have a manual that might decode this flashing signal from my TV?

    I have this same problem, but there is no way I have the skills necessary to fix it myself. Does anyone know how much this would cost to have repaired by a professional? Hopefully it's not too much, I really don't feel like buying a new TV at this point.

Buy a new TV, because it's not worth fixing. Q502 replaced with no change for me, and board replacement on a TV this old just didn't make any sense vs cost of a new SDTV to replace it.

Ok Gentleman here is your solution for this problemo. 1-buy the service manual with schematic drawings from Sony or any other dealer price $12 usa. 2- Go to the page 35 and you will look a device transistor whose ID is Q502, this tnt is installed in a HEAT SINK PLATE IN C SHAPE. 3- WITH DigitalMultiMeter CHECK THE RESISTANCE BETWEEN Base TO Collector (B-C) and Base to Emitter (B-E) the values measured should be in the range of 5 to 10 Ohms.tha is OK. 4- reverse the polarity of the DMM and the values measured will be in the range of 0 ohms. that is ok. 5- in the event of checking the ohms values between reversed polarity item 3)the values is quite similar in the range of 5 to 10 ohms , the transistor Q502=C5426 MUST REPLACED. 6- THIS Q502 IS THE HORIZONTAL OUTPUT TO DELIVERED TO THE HV TRANSFORMER. GOOD LUCK IN YOUR ENDEAVOR. TV SET GUY

4 blinks indicates the vertical deflection has stopped. i would suspect the vertal ic has gone bad. if ic is good check the +13v this is supplied by the "A" board but it powers the ic. if i remember right the vertial o/p ic has the board marked as ic541. good luck

According to the manual... Problem: 'a red light keeps flashing on the tv for more than a few seconds', What it could be: 'your tv may need service', What you can do: 'Call your local Sony Service center'

I have a sony trinitron 27 in. model KV-27S45 1998 it will not turn on and the stand by timer is flasing 4 times dont know what to do

Vertical IC inside your Sony TV has damaged [shorted]. Four blinks of standby light denotes it. The number of blinks of standbylight in Sony denotes some fault, and can be determine according the the continueous blinks. In your case, the standby light will blink four times, then stop for a while and will continue to blink four times and so on. Vertical output IC should be replaced with same type and number. If you are aware in electronics and have tools, you yourself can do the work.
If you wants anymore assistance, feel free to get me by Fixya.

Sony trinitron 27" tv not working

Hi. If the picture was good before set went wrong then I would say yes get it fixed. Frame fault is pretty straight forward for tv shop to repair. New sets regardless of make will not last 10 years before they go wrong you will be lucky if a new set lasts 3 years before going wrong. At the moment in the repair shop I work in we are scrapping off LCD & PLASMA that are under 3 years old they are very expensive to repair.

Sounds like you have a short in your set. Probably a shorted horizontal output transistor. You need to have a tech check it out and give you an estimate for repairs. Stargazer
