hello, you should press the display button
at the remote control that marked with the i letter or with the ? sign

Or where it says the word DATA

I hope that was helpful! Let me know if you need further guidance

Lines means Screen Drive is overdriving, try adjusting the Screen control on the FBT flyback Transfomer, adjust it down. If that does not Clear out Problem then replace the CRT Board that is connected to Picture Tube.

first check the speaker setting in the menu see if the speaker is selected ON. if the speaker is on then check the SAP function of the set. check this with the remote with the MTS button on the remote. keep hitting the button untill the word stereo appears.

Hello
Blinking of standby light in Sony telivisions are fault indications. You just count the number of blinks occur at a time when the set is switched On with its FRONT PANEL POWER SWITCH. Count it three or more times, and make sure about its number of blinks and inform me through Fixya. From that number, I can get into the fault section, sometimes more accurate to the location of the fault. Count it Keenly for at least three times and make sure before reporting. OK.

There is something wrong with your set's vertical deflection. To prevent picture tube damage, the set blanks out the screen and flashes that 4-blink code. This is usually because the vertical output IC has failed or there is some other defect in the vertical output circuit, or a problem in the power supply so the vertical output isn't receiving proper voltage.

The vertical output is IC451 on the "A" board (the largest one holding most of the parts). You can try checking the solder connections to its pins, which is a common problem in all brands. Or you can try replacing the IC. But beyond that there's not much you'll be able to do without a voltmeter and the circuit diagram.

I would recommend having a professional check the TV if you want to keep it. TV service requires some special tools and experience to locate the bad parts, and there's the possibility of personal injury or causing more damage to the TV if you don't know what you're doing. Or use this as an excuse to buy a new TV. Small LCD sets are quite inexpensive now, and a new TV may be not very much more than the cost of repairing your TV.

Good luck, and thanks for using Fixya!

Hello

Your TVs power ON/OFF switch has got some trouble I thinks. it may be dure to its locking mechanism, inide it which keeps it locked for one press and the relese it back for an other press. If so it should be replaced, and no repair work can be done with it. As far as Sony sets are concerned, this switch will be of special type, and have different diamenstion to that of otheres. You shoud resolder it out from the circuit board and go for a new one with that as sample. Replacing it will solve your problem. OK.

If your Sony has built in Freeview, go to the menu and find "Subtitles" turn them off. Or if you are using and external freeview box, do the same in the boxes menu.
That will fix it.

replace your tac switches maybe one of the switch are defective.

Sounds like it is flashing probably 5 times?
The green tinge is the tube wearing. A new tube will fix it.

Hello

There is some fault in the [AKB] circuit section inside the circut board of your TV. To rectify it, you have to open your TV, and check the video output section. It can be located at the picture tube base card

AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Turn it slightly counterclockwise, not too much,just one point.

The reset can be done if you have the remote. Turn on the TV. Hold down the Reset button on the remote, then press and release the power button on the TV. The TV will turn off and then on. Once the TV is back on, release the Reset button on the remote.

If you need a replacement for the original remote, try the Sony Parts and Accessories store.

Alternatively: remotes.com has a substitute remote as well as used original remotes: http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=12881528939530&smodel=KV27FS100&brand_pn=SONY_KV27FS100 .

I hope this helps.

If you state that the contacts of the Mains Plug were 'burnt', I suggest that you once clean them with Emery Paper and try again. Loose contact in the Mains causes the 'burning', and the Plug contacts become carbonised. Could be other reasons also, but just try this first.

The display fuction in your TV is on. Go to menu, navigate through it, find the display items chareteristics, hilight it and turn it to off with the help of 'vol' button.

The lights blink on start up and if all is well the set works.
Remember when all was well and how it started?
If it does not come on then the number of blinks is a suggestion to the failed section of the set and it needs repair.
Your owners manual or local repair shop will know but a 10 year old set might be considered a full life.

Are you by any chance using Closed Caption?
The channels that do appear are they full screen?
How about what the picture is on a DVD through the Video inputs.?
Please fill us in on these suggestions.
