SOURCE: sony kv xj29m50 no picture.

If I understand you correctly:
The horizontal output transistor in your TV blew.

You replaced it with a BU2520DF.

I'm not sure what you mean by "change to dynamic mode".

Dynamic what?

Usually, horizontal problems in TVs are caused by bad capacitors in either the sync circuit, the driver circuit, the geometry circuit or the output circuit.

When I repsir problems like this I use an oscilliscope to find which stage is not working properly, then start substituting the capacitors in that stage until the problem is solved.

Look for large orange or blue ceramic or polyprop capacitors with bulges or cracks in them.

Look for electrolytic capacitors with bulging tops or shrunk cases.

Check and make sure no resistors are brown, they may be blown.

Use an ohm meter to test low value resistors in circuit.

If you don't have an oscilliscopw, that's about all you can do.

Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

KV-XJ29M50 29" TV-Loud thumping sound on startup


Symptoms are not related,what you hear is the high voltage turning on and that is normal if it only does it for less than a second,the grainy picture might be intermitant,dont turn it off,when the picture is grainy tap the side of the set to see if it racts and if it does you know you have a loose conection.This could be outside because of a loose ground on tha cable or inside in the tuner.
