The inputs you refer to should be colored as follows. Red Blue Green Red White (not necessarily in this order) These are what are called Component Video inputs and is one of the way that HD capable equipment connect to your television. It will not get true HD picture but this input will provide you with a crisper clearer picture.
Yes this thing start happening to my tv too about 4weeks ago and this goes away in about 15 minutes. TV is only 18 month old and I donot have extende warranty. Please post the solution if someone has got it repaired. Thanks
YOUR CRT (PICTURE TUBE ) IS GOING BAD . this is the most common way a sony tv crt fails . the tv is to old to make it worth a crt . but if your handy and carefull there is a way to get a little more time out of it . start with the tv cold , remove the back and look on the little board connected to the neck of the crt . there is a control marked "SCREEN " plug in the tv and cable and start it , with it flashing adjust that control , one way will make it flash more and one way less , adjust this no more than you need to , just enough to stop the flashing .NO MORE ! just be carefull the voltages in a tv can KILL . dont touch anything else in there and use a little inslated screwdriver to make the adjustment good luck .... if this answer helped please leave me 4 stars rateing , this high rateing will keep me in the paid answer department , thank you
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.
TV Repairman came out today to look at my Sony KV-36XBR250 today with the exact same problem - he was able to adjust the settings through the service menu, but said it was a temporary fix only.
The picture tube is going and the Sony circuitry has a "video mute" that it uses when it senses the tube is not warmed up enough. The degraded state of the tube causes the blinking on and off as the signal from the tube wavers.
He ballpark estimated the tube replacement cost well above the price for replacing the set with a 37" LCD, so it's going to the dump...
stilltwitches near upper and lower edges and occasionally through the middle.
the above problem is due to horizontal oscillator section .
some capacitor is faulty in that section.
if you are not tech. person please call tech. to fix it.
it is not a major problem.
also please check for little sparking in high voltage section.
hope this will help.
Your whole problem my freind is dryed up capacitors. You should go, if you have the technical ability to replace these capacitors, to http://servicemanuals.net, download the schematic diagram, and start replacing the waveshaper capacitors in the vertical drive circuit.
