Question about Sony KP-53S25 53" Rear Projection Television

1 Answer

White Noise first, then picture on Sony Kp-53S25

Hello everyone, first, I'd like to thank this marvelous forum, lots of info and that translates to lots of $avings!
I'm having this annoying problem with my tv (12 year old btw); when I first turn it on, there's no picture, just static noise, after about 5 ~ 10 minutes, there comes the picture and stays put as long as the tv is on, a little "interference" here in there but viewable.
This happens when getting the output through the VHF connector. If I use the Video1 ~ Video3 the picture comes up instantly.
Any hints?
Thanks a lot in advance guys!
BJ

    Thanks Dan!



    Also, I'll check for any visible symptoms on the tuner and solder joints as well, any hint on where to buy the tuner from? just in case it's the last resource...

    Guys, specially Abrsvcs, Thanks for your comments and replies, even if you guys didn't replied and just read this thread!



    My TV has been fixed now, this is what happened:



    In a different thread I posted a Convergence problem; then one of the guys there suggested to replace the STK392-010 IC's since I couldn't adjust the convergence from the TV's menu.



    Got the IC's for about $40.00, replaced them and now my TV has a nice clear and crisp picture!!!



    BTW, no more white noise static at power up!, picture kicks in immediately (just the way it supposse to!!!)



    Thaks again guys, this forums are great!!! Keep up the good work!!

    Guys, it's me again. Ok, after replacing the convergence IC's my TV has been good, colors are all adjusted, nice clear picture.



    Now, the white noise after first power up is back :(



    it happens evrytime the TV is power on, it takes about 5 ~ 15 minutes for the picture to kick in. Also, when there's picture, I've noticed that intermittent "flashes" like static disturbs the pic and sound, sometimes more than others.



    Any hints?



    Thanks in advance guys!

There are poor connections in the tuner or the tuner power supply is takeing a while to settle down. Worse case is that the tuner needs to be replaced. Figure on $75 for the part if that happens. I'll look up your model later to see if there are any common problems with this symptom.

Don't know where the fuses are on the Sony kp-53s25 1996 year. Tv won't turn on, makes clicking noise and then standby light flashes. harrism55@yahoo.com


the first thing you can deduce is the main fuse is good. secound the power on relay clicks whick means the set is trying to come on. the standby light flashes... how many times what is its pattern this could be an error code that could point in the direction of the problem

I am having trouble adjusting my colors for my kp 53s25 there seems to be a lot of yellow how can i solve this?


This TV has had a long life. Your picture is looking more yellow these days because the Blue picture tube is wearing out. Not saying the Green and Red tub are much better, but Blue tube is a major player in the picture brightness and white balance (the color of white which the TV reproduces). The cost involved wouldn't be justified. You should enjoy the balance of the TVs life; when it's time comes... have the new TV delivered and ask them recycle this one. Best wishes.

Red screen on my sony kp-53s25,


That model is famous for bad green CRTs which can cause the screen to take on a red hue when the green cuts out that can also cause the set to get blurry also. Let me know if you need more assistance.
