Sony KV-20FS12... | Answered on Jul 30, 2012


Hello
In fact your Sony tv id s dead I should say. So you have to start diaganosis from its power regulator section itself first. Locate that section, can be easly done by following the power chord goes direltly to it, and check whethere there is any loose or bad soldeings on the print side of that section. It is very difficult to locate the loose solderings, as they will be somtimes micrscopic, tha our eyes can't detect. So I advice you to resolder most of the soldering points there, without making any solder bridge between the coldering points. You must have some concept about soldering. Apply a little more solder ot each point while doing this. In most cases this will wolve the problem in Sony sets.
The components in the power regulator section will heat up while working, and repeated heaating and clloling may make some of the solder points to get loose contacted. Especially, the soldering points of the leads of the regulatror IC, and at some ponts of high watt resistors used in that section. Do this an chek out. if you wants anymore assistance, feel free to get me through Fixya. OK.

A 20In set would probably be around 136v (give or take) while running and would go much higher if it was going into HVS (High Voltage Shutdown) 180v or so. The power supply is working (you have voltage).
Do you have a glow in the neck of the CRT? If not then it may be a bad resistor for the crt heater circuit. Most tubes use the top two pins on the neck socket for the heater, trace them back looking for a resistor, or simply test for voltage at the heater pins (AC), should be low 2-5 volts. If it is shutting down check the Horizontal Output Transistor (HOT) by using an ohm meter (with power disconnected :) ground the black lead and hold the red lead on the center pin of the HOT. Ideally you want an open circuit reading or very high resistance (MOhms), if you have low resistance it means either the HOT or the Flyback Xfmr is bad.
Hope this helps :)

It sound like you have abad picture tube. Iknow this is not the answer that you want to hear. Sony's have video blanking circuit built into the video processor(in the jungle IC) when the emission of all three gun fall out of an acceptaable range. the screen blinks and when you turn the screen control on the IHVT all you see is re-trace. Some times there is a current limiting resistor in series with on lead of the heater on the crt board. By changing this resistor from 2.2 ohm to >.1 ohm @1/2 watt you can sometimes increse the filament voltage to the point that the blanking stops. This is only a temporary cure not a fix. The picture tube is probably bad. Scrivitron

First, unplug the tv set for 30 seconds, plug back in and try ti turn on.. Second, If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV not to turn on. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!

After the replacement of the main board; a software update might be necessary to any TV. Contact any service technician, of do it yourself, if you know how to do it. Or Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

Here is a question that we see often.

Question:

I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ?

So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what is does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part your put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'No Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous use it as an excuse to get money for selling items that may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $2 parts and an hours labour. Take it for service.

The RMT-TX1020 is not a remote that I find online. There is a Sony RMT-TX102U which is included with several models, including the KDL-32R500C. First, what input are you using on the TV? If you are watching OTA (analog or digital), then if captions are available, you should be able to press the Subtitle (CC) button below the Channel Up/Down buttons on the remote. There are three choices for Caption Display: On/Off/On when sound muted. You can also adjust the type of captions. In most cases, you'll want to use CC1 for both Analog or Digital captions. Navigate through the menu using the select (the center + button) and the arrow keys as with all the other menus. If you are using a set-top box (cable, streaming, Blue-ray player), you probably need to enable the subtitles or captions at that device. It could be in a hardware settings menu and not a function controlled by their remote control.

My current TV setup includes IPTV (fiber-optic internet). To enable subtitles, I need to go to the Menu and then to Settings. Then I enter a password provided by the ISP and go to the Hardware > Audio > Captions menu. On a neighbor's satellite dish receiver that served two TVs, enabling captions on the second TV (for their hearing-impaired relative) required enable captions in the Hardware settings for the primary TV.

The subtitle button usage is described on page 30 on the manual for this TV. Sony has the manual on the product support page: https://www.sony.com/electronics/support/televisions-projectors-lcd-tvs/kdl-32r500c. The current link to the manual is https://www.sony.com/electronics/support/res/manuals/4562/45622791M.pdf .

I hope this helps. Please add a comment with the video source for your TV if you want further assistance.
