My sanyo tv have standby power. and then cannot switch the secondary switch


Hello, it sounds like a power supply problem. When the powersupply in the tv detects a short or a problem it automatically reverts to safe mode or standby. It could be just a resistor or it could be something else. If its just the resistor or similar you'd be looking at around $100. Get a couple of quotes and pick the best. Thank you, I hope Ive helped.

EHT Faliure and kindly give me the alternate EHT details .


Hi Rayjanardank
Eht on all modern ctv is generated with in the flyback transformer , although some older tv set use a triplier unit feed with a 8kv pulse from the flyback transforme
To find out the one that you have got , if the flyback transformer as two controls A1 and Focus mounted on it then the eht is generated inside, if the Focus contol is mounted on the tippler unit unit .As you do not state the make mod No of tv i cannot be of any more assistant but you could cheek the A1 voltage on the crt base , if this is about 350/430volt then the eht should be ok. Hope this might help with your problem.
Regards windyhouse.

The solder joints on the CRT board might have cracked and cause this symptom. What you are describing indicates that the red gun is intermitten, and the solder joints on the CRT socket itself (red cathode) or the red output transistor have probably cracked loose.
