Sounds like a loose contact. Check all the solder terminals at the horizontal output as well as IC terminals, for any loose or dry solderings. Re-solder all the suspected solder terminals, by applying a little more solder, without making any solder-bridge short in between adjecent solder terminals.

Hello!. When the set goes off does the front red led blinks ? thats an error code. If it goes only to a horizontal thin line then back to full frame its the vertical deflexion IC that causes the problem and it happens a lot on these sets because of internal temperature and bad soldering issue.

the problem there is a loose connection on the board,you said that you smacked the right side of the tv and it goes normal.there are parts that should be resolder on the board in order to back into normal operation.

SOURCE: Canno turn the tv on.

You probably have a main or high voltage power supply problem; the latter produces the 20,000 plus volts for the CRT and gets its voltage from the main supply. It's difficult to say which is at fault without a few measurements.

Horizontal


If you wish to get more details about how to pull out the chasis out to service position, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.
It has illustrations about disassembly.

Screen not coming on


This Chassis line had a lot of issues with hair-line cracks in the Horizontal Circuit along the right side near the High Voltage Transformer and Heat Sink. It has also had issues with cold solder connections in the Horizontal Drive Circuit especially the Horizontal Driver Transformer. These issues have many times caused a massive Power Supply and Horizontal failures if not repaired.
I hope this helps,

Half screen


Hello xmen0614,

If the screen is halved in a horizontal fashion meaning that the screen only goes up half way this is an indication of a vertical deflection problem, quite possibly the vertical coupling capacitor or a problem with the vertical drive signal. If the TV is halved vertically meaning the either the left or right side of the TV is black while the other has picture, this could mean a problem with the damper diode, the Horizontal output Transistor, or the horizontal drive signal.

In either case I would suggest doing a ring test on the Yoke Transformer, The IHVT (Integrated High Voltage Transformer).
Also check the Vertical coupling capacitor, and the horizontal drive transformer (Ring test this).

You noticed that I included the Vertical and Horizontal sections? This is because you did not mention which direction your screen was halved in.

If it is halved to to bottom check the vertical circuitry, If it is halved left to right check the horizontal circuitry. For either one do a ring test on the Yoke Transformer.

I hope this helps,

Thank you,

Shuttle83,

DTV converter boxes


You need to look on the tv and see if has a digital turner symbol. If you can only pick up analog channels, you need a converter box.

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
