randomdes;.... Sorry about the delay.... I did not have your specific service manual.... I do now....Since I'm on a slllooooowwwww dial-up , it took awhile to download.... 1st , let me answer the previous posts;=>... By CRT do you mean the entire module with deflection yoke, lens et al? NOPE..... There's no way i can see to hang the tube in free space with those cables connected. Perhaps I'm missing something? That is correct & yes , you did miss something....You missed the word "module".... The CRT module is the small little circuit board at the bottom of the CRT.... It just slips down off the CRT... Then move it aside so it's not near any other wiring or metal.... I get a blue glow, might have blue lines on it. Then as the other 2 guns power up, i see a white screen with curving R,G,B lines on it. It would be nice to see the curving R,G,B lines.... Is there a way you can take pix & post them ???? From jts1957;=>.. He means unplug just the CRT neck board and let it hang in mid-air. Yep , that's exactly it......... OK , I'm caught up........ The reason for the delay is this statement set bells off;=>.. By CRT do you mean the entire module with deflection yoke, lens et al? This tells me that you lack some or all electronic/TV repair experience... What I intended to do was post a pix of what I want you to disconnect ie, the CRT module & NOT the CRT "assembly".... We seem to have gotten past that while I was downloading the manual... If not , let me know.... So , go ahead & remove the blue CRT module as I requested in post #2 & post results.... I seriously doubt that the flyback is causing any trouble.... Also , I suspect that 8 blinks is from an older problem.... We need to clear all the old error codes , so we can get fresh codes , if any.... You WILL need the original Sony remote.... The following is from a website that has all the codes for Sony Projection TVs=>..... ""After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition."" The above "may" not have been done after past repairs.... Please note the "coma" between "channel" & the number 5... I think this is an error (typo).... If memory serves , there's NO channel button on the original remote.... They're NOT reffering to Chan + or Chan- , which is on your remote.... So , after you press "display" , press number 5 , etc... Start this with the set OFF ..... After you finish , turn the TV off at the front panel (NOT with the remote).... Unplug the TV for a few minutes , plug it back in & turn it on.... Count blinks , if any , & post.... Have a GREAT evening........ Later....Ron.M........ Veteran & Retired TV technician
