When I open my RCA TV 25648 it shut down after a few second. Is there any way to fix it ? Thanks


IF LED IS BLINKING then............. 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 ..........IF LED IS ALSO OFF then on main board in power section area some component is deffective ... MAIN BOARD SHOULD BE CHECKED COMPLETELY........ 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 from bangalore (09986222774, [email protected] ) .....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact RCA service centre.........

When we try to turn on the tv, it chirps and shuts off


Power supply (switched mode) is shutting down due to either a fault within the power supply itself, or a problem in the line stage (EHT) and the current protection circuit is shutting down to prevent further damage. Flyback diode often fails shutting the power supply down.

A circuit diagram is required in order to repair this.

Rca truflat tv goes blank after 30 minutes, then I can't get a


When this goes off is there a loud crack? If so perhaps the B+ supply is increasing increasing the the EHT to the CRT and the crack is the voltage across the spark gap in the crt base jumping to chassis/earth shutting down the TV. Or perhaps just a dusty/dirty eht cap, again EHT discharge, or could be a eht tripler being faulty. Further investigation with the aid of a service manual is required I am afraid.

I have a Hitachi 57F59 Projection Color TV. Last night it started making poping sounds like an arc short and the picture would go in and out. Finally after one really loud pop, no picture. Looking in...


It has a common line output stage for the three tubes. It is most likely that the EHT unit has failed and it may have damaged the line output stage. The two faults are repairable to component level and will not need a new line board just an EHT unit. If you have sound, the power supply part is probably OK. Tell the tech to see page 124 of the service manual for a full schematic..

Tv set won't start up


as your reg. output is 40v & you have checked every possible things responsible for it. my suggetion is that first you isolate power supply from hor.section & see if power supply output is ok. if it is ok then check for short & leakage in h/output like 1 hor.output tr. 2 diode or cap in eht winding. 3 check for print near eht transformer. 4 disconnect yoke connector & check . 5 & finally eht or flyback transformer.
