IF LED IS BLINKING then following is the situation.............. usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective - so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 (US$ 12) - iam service engineer (computers, laptops, printers,etc) - bangalore - domlur - 09986222774 - firstname.lastname@example.org - if you are in bangalore then you can call me for service - i think you are living somewhere in america /australia..... - problem is simple but i don't have any idea about EHT COMPONENT 's price & service charge in your place.......IF LED IS ALSO NOT BLINKING then following is the situation............fuse is gone due to deffective component in power section ....BOARD HAS TO BE CHECKED..............so my suggestion contact near by TV service engineer or approach RCA service centre ....this problem cannot be solved by user unless user is a technical person, having idea about components (resisitors,transistors, diodes, ...etc), having tools like multimeter ,soldering iron , soldering lead ,flux, desoldering coil, etc....
hi there! if you know how to troubleshoot technically this will solve your problem. 1.check the horizontal section of your tv , there you will see the flyback system connected at the back of the picture tube, never touch it because there still a remaining voltage charge on it , electric shock might happens if you remove it improperly. 2. check all the components inside the horizontal section only & look for possible cold solder at board and fix it if you know how to use the soldering iron and Pumps. 3, replace the defective component if necessary thru the help of expert tv technician in your area. Thank You
I Do not know this make/ mod but this type of fauly is due a short on the ht line causes are a faulty line flyback tranistor( emitter/collector sc) Another possible cause could be a faulty line flyback tranfromer. parts might be obtainable from seme/nedis on www.semenedis.com
