screen went dark with a flash of green down the middle pip is dark also,have audio.Can turn set off for 1/2 hour to over night,it'll come on & look great for anywhere from 5 min. to several hours.Had in home repair for the same symptom about 8 1/2 mo. ago,repairman suspected a horiz. problem,my wife said it took him longer to open up the set than to make the repair,she didnt see all that he did, it would seem that a circuit opens intermittantly. I have built several electronic kits,including a Heathkit color tv, so i'm not bashfull about opening this set if you can point me in the most likely direction to go, for a old toot my hand is still pretty steady with a soldering iron . Beside keeping it unplugged,what else should I do to not make things worse removing or damaging something that shouldn't even be touched , she did say that he worked on the lower left side looking from the rear. Am hoping to keep this this set working for another year or more. didn't know about this site till recently or i'd not have had someone else work on it.I've read most of your answers,now i'm thanking you in advance for your help;don bolt

I don't have experience with this, Don, but it does sound like horizontal, or power supply.
What I can gather on these Sony's is that you need to check Q601 and Q602 for shorted, and R607, which is a fusible resistor. I highly suspect bad solder joints in and around the horizintal section if this is the case. If you have to discharge the HV CRT lead, you may want to make a 10 Megohm bleeder (I usually use four 10M, 1/4watts in series-parallel, 2 by 2 for 10M 1W total) on a clip lead, and use it to ground a screwdriver shank to the CRT chassis. With the bleeder lead clipped to the screwdriver and chassis, slip the screwdriver under the rubber cup and let the voltage drain off for a few seconds. Hope this helps some.  |

OHMIE,thanks for the reassurance,I haven't opened it up yet,my wife doesn't give up so eaisly and it seems neither exactly does this set. Here is what is hapening now;she programmed the set to turn @ 6:00 pm & off at 12:30 am,yesterday sat 15 oct it came on w/good pix & audio,after a couple of hours she noticed the PIP didn't work,she then turned off the auto shutoff & it has been running ok otherwise for the past 20 hours,dont know when she will turn it off to see if it will keep working or not,"the weather did start to cool off some about noon SAT, about 6 hr's before this spooky phenomina started. does this this change give you any better feel for what ails this thing,does this reinforce bad solder thoery or should I use magnifying head set to try & find a visible open circuit??? thanks again for all your help don bolt

So, you're saying that it's working? And keeps working? So you just don't turn it off?
