SOURCE: picture went out

I can think of a few conditions that would fit that symptom, my guess would be problems in the vertical circuit which are somewhat common in that unit model. First I would test R561 0.47 Ohm for an open condition and test and/or replace IC541 with a TDA8172. IC541 is your vertical output. Another suspect would be vertical yoke windings. Maybe not short at the moment but could be shorting intermittently. You would have to have the windings ring tested to prove the theory. And lastly - depending on the distoritions I'd ring test the flyback transformer for intermittent short, sony p/n#1-453-268-11 and test the B+ (high voltage) as it comes up and at the point of failure. Any surging would be dispositive of a voltage regulation failure. Nine years is a good long time but there is no reason that this unit can't operate another 5-6 years. The repair diesn't sound too serious or extremely expensive for a reputable shop. If you need any help locating one you might try the NESDA web site: http://www.nesda.com/locator/state_search.php and I would take the unit to the shop rather than have them come and pick it up - even though it's so heavy- it will save some money. Sorry for the bad news, as a certified tech it's the one thing I least enjoy is giving bad news in a solution. Good Luck Bill

SOURCE: Sony Trinitron - Picture Disappears

Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

No, if the picture of your tv screen is clear when when you watching. the troble of your tv is looseboard, and you replace your CRT socket too.

We bought a new fan for our xbox 360 on sunday and yesterday while playing Modern Warfare, the screen went completely black. We tried different tv's, but the screen stays black. We can hear noise like...


possibly unrelated. try testing the connections to the tv and the x-box. if thats solid then try removing the fan unit to see if it is the culprit.

The picture doesnt show but I hear the sound.


Don't worry the HD feed from the xbox 360 has a gain limiter
So the chances are more likely that either your Friends xbox has
the HD setting off or the TV has defaulted to standard video in.
If you get a black screen or a mesage that says no single .
But if your getting strange color on your set with the HD on
then we need to investigate this " Microsoft is liable!" for
damages caused by their console. Ill look in to this and
follow up. The xbox has broken connection under the poorly
soldered G.P.U. and will need to be re-flowed to the main
board to corrects this problem but that's a secondary priority
right now.

I'll check this out for you and follow up.
