Sony KV27XBR37 suddenly stopped working
Hi All:
Please help. My Sony Trinitron TV (model KV27XBR37) suddenly stopped working today after 8.5 years of flawless performance. This is what happened: - all of a sudden lost picture, but sound was perfect - tried switching on the VCR (trying to watch through that) but no picture - the 'timer/stand by' light kept blinking during this time. - I switched it off, checked all the connections, disconnected from main power supply and then connected again. Switched it on, but got only the sound, no picture and the 'timer/stand by' light continued blinking - and then all of a sudden it just died, as if it was a timer to die. I am not able to switch it on. - I smelt a faint burning smell in the room which I could trace it back to the TV itself, but have no idea what it could be. Please help. I have no extended warranty left on the TV .. looking for any help. I bought the TV in Dec 1994 from Circuit City. Calling Sony didn't help .. they just referred me to a local repair place. Thanks very much. -- Bill |

techtrainer:
There are many dozens of different faults that can cause the symptoms you described.... and in light of the fact that you did not post any basic technical troubleshooting information what so ever such as DMM voltage readings, component test results, etc, etc .... I think that Sony's telephone advice to you was absolutely correct...... get your television to a service shop for a proper and safe repair.... or at the very least have the shop give you a repair cost estimate so you can make an intelligent repair decision with facts instead of internet guesses. This can not be done over the phone or over the internet..... an experienced and knowledgeable tech with actual test equipment, tools, proper replacement parts, etc, etc must do some real hands-on testing and troubleshooting in order to determine the fault. While this model of Sony is an excellent television it can present even an experience repair tech a challenge to repair..... an inexperienced novice without the proper test gear won't have a chance. Without you doing the initial basic troubleshooting at your end all we can do is give you wild guesses. You might want to go to the website for this newsgroup at http://www.repairfaq.org/ There, with some searching, you will find a wealth of troubleshooting tips, repair procedures, component testing methods and IMPORTANT safety information that will help you to stay away from dangerous and lethal electrical shock hazards inside your television.... note that these hazards can still be present even when the television is turned off and unplugged.... be very careful. If, after reading through the repairfaq, you are still not certain how to proceed with the troubleshooting and repair you should follow Sony's advice and take it to a local repair place..... it might be safer for you and better for your television. -- Best Regards, Daniel Sofie Electronics Supply & Repair -------------------------------------- "techtrainer" wrote in message om...

Thanks, Daniel.
Yes, I agree .. I was not going to try opening the TV and try to fiddle with anything, probably too dangerous. It was probably not clear from my message, but I'm hoping someone on this group may have had a similar problem with this model TV. So to rephrase, anyone experience something similar .. if yes, I'd love to hear your experience.
