Question about Sony KV-35S26 35" TV

4 Answers

Won't turn on

My tv is about 10 years old. Worked well up until last month, then stopped working. Nothing funny happened (noises, picture was good) - just quit. I took off the back and checked the fuse - it was good. Have verified power at this outlet is ok. I assume it's something to do with the board that controls power to the tv - any ideas on how to search out the problem?

1-1st check the standby light.
2-if ok check the powersupply in the rectifier bridge.
3-check the following transistors R623, R622, R608, R611
4-check power supply in regulating ice or driver.check if the smps transformer is shut.
5-if that does not help fault is surely in horizontal oscillation section.

This model is the AA-2 chassis. They have a unique problem in theier power supplies. Locate Q502 and write down the number of that transistor. Then go to the link I am posting here. They have the repair kit for your sony for 6.99 it contains the horizontal output (Q502) both regulators and resistor that commonly short in these sets. They sell 2 kits. just click on the kits one at a time and it will list the transistor numbers. get the one that mathces your Q502 it will be a 2SCnumber. That should cure your problem. If not the only other component you would possibly need is the power IC601 that cost 10.00 but go for the repair kit at 6.99 that repairs 90% of this models power supply problems. They offer fast shipping as well. Here is the link the kits are on this page.

Hi there

if you want to do the good old check 1by1 thingy, you can always use the GoodOld Tester... it may be thought becuase it may take you some time to do it. but if it makes you happy...by all means right. :)

just be careful though because as you described your tv, "just quit". you may want also to do of heiarchy test starting from capacitors all the way up until the tube.

my advise...when in doubt, you always have the choice to bring it to a service center. a 10 year old tv always have sentimental value. :)

cheers.

HI,
First thing to do is the reset and the whacking test. I give this a 50/50 chance of clearing it up.

ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.

TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

If these two procedures do nothing then:

The Sony blinking code gives key diagnostic indicators, but still, it will require a tech to dig into that section identified by the diagnostic code in order to find the specific default.

Thi xbr sets are famous for AKB circuit failures. This circuit (autio kine balance) detects when the tube warm up is ready for video to be displayed. Most of the time it is due to defective AKB circuits rather than defective picture tube elements.

The repair will cost around $200....... If your set is marginally qualified for the repair; otherwise, you might be better off (financially speaking) to replace it. You will have to decide.

Goodluck,
Please don't forget to rate me as fixya..

So I had this RCA Analog TV set since 1999, and there has never been with it til now... Over the last few months, it would automatically turn off when I turn i after an 1 hr when I would be recording...


Regrettably, 15 year old tv's eventually give up entirely. Sounds like your power supply is finally giving up. Typically these tv's are not economically repairable (most repair shops wont touch them because a new tv is cheaper. Be happy you milked this set for 15 years. Pawn up some of your other extraneous stuff an purchase a $200 flat screen.

Scepter 32". Received this for Christmas 2012. It's worked beautifully up until about a month ago. When you turn it on the blue light comes on but nothing happens. You can't turn it back off without...


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
It's not unusual for this type of electronics to only last a couple of years.

Toshiba HD ready TV ct 90158 makes high pitched sound


A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

TV wont turn on, makes buzzing noise and shuts off


I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
