Question about Sony KV-32S42 32" TV

1 Answer

Sony KV-32S42 (See Description)

Ive had this sony tv for a couple years now. it used to be a great tv. lately, it has taken longer and longer for the screen to turn on. now, when i turn the tv on, i get sound, but the stand by L.E.D. just blinks and blinks. no picture. after 5-10 minutes, the screen might kick on, but that also keeps blinking.

ive seen some of the other posts. most of the answers were to take it to a repair shop. but i'd like to try and fix it myself if possible. what could be wrong (please clarify, im new to tv fixing) and how much would it cost to repair at a shop?

-Thank you

It may be a fruitless effort. The main reason this occurs is that the Picture Tube is drawing too much current and the AKB circuit will not let the video circuit diplay the picture. Outside
of replacing the Picture Tube there is no fix.
You can varify this by turning the screen control up. This is usaully located on the HV transformer and is marked. the other location it may be is on the CRT board. It also would be clearly marked. If you adjust this slightly and the picture appears, the Picture Tube is the problem. I'm betting 100% it's the Tube.
Hope this helps,

    It is the bottom knob on the HV Transformer. Turning it clockwise and seeing if the CRT face lights or flashes. If the CRT has a bad enough short in it, it may not light up at all. But I am still betting it is the CRT.

How can I turn the screen voltage up?

from description you are on the right track--screen con inside will either be on the crt circuit board or on the high voltage transformer, on or the other--lots of the older Sony sets when the picture tube gets weaker need this done.

Standby/Timer LED blinking

These unit are famous for the PCB Print to be cracked around the HV Circuit and or the Horizontal Drive Transformer pins needing to be resoldered. It can turn into a very Major repair if the HV Components short. In that case the Power Supply will also short out.
Hope this helps

Adding a audio jack to KV-32S42 sony TV

yes, just tap in at one of the speakers. The jack should have an internal switch so that the internal speaker is hooked up when the headphones are not in. Most TVs are now stereo (even though analog broadcast signals are mono) so may want to get a stereo jack and tie in from both speakers.

No picture

I hate to be the bearer of bad news, but what you have is the Sony classic bad picture tube. All the events which you described were coincicence. When a Sony picture tube is weak there is a circuit which detects emission from the guns , if the emission is low, a video blanking signal is applied. Sometimes you can turn the screen up (inside of TV, Not recommeded for non-technicians. an you may get a watchable picture. This however is not a fix. The picture tube is bad. Replacment exceeds value of unit Sorry. Scrivitron
