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.

TV: Sanyo 21 inch tube (about 10 years old) When TV powered on. When I try to manually or using remote bring picture on (i.e. by prg up or down), the power on indicator light starts flashing and nothing...


You have a power supply problem.
The microprocessor has its own supply and is not receiving a "hand shake" from the line output stage that in turn is not receiving and power from the power supply.
The chopper transistor will possibly be short circuit taking the feed resistor with it.
Check for dry joints everywhere and MAKE CERTAIN THE HT CAPACITOR HAS DISCHARGED!!!!!
Hope this helps.

I have a older sanyo ds19390 tv that is buzzing inside, not thru speakers please help


In older tvs the buzzing sound usualy comes from the HT lead plugged into the tube .open the back and switch the tv on (do not touch anyware near the set the HT lead carries avery high voltage even when the set is off)if u do see arching then u need to clean around the rubber of the ht lead )u can leave the set unplugged for a couple of days to allow the tube to discharge before attempting to clean around it.

1 Answer

No power


It sounds like you have a problem in the set's power supply or high voltage section and the set is protecting itself from turning on. Unfortunately, you'll need to take it to be serviced.

Please let me know if I can be of further assistance to you.

Good luck!

On and off picture and color weak Sanyo HT30744


I had the same problem with my refurbished HT-30744 model and my mom's HT-32744 model. It was either try to fix it or buy a new one, so I figred had nothing to lose.

I removed the back cover, unseated the picture tube driver board from the neck of the picture tube (it just pulls off), put on a dab of di-electric grease on the connector on the card, reseated the card, removed and re-applied more grease, reseated the card and the picture has like new for 2 weeks now!

This was a very easy fix.
