What could be a cause of my sony trinitron 21''crt tv it's problem is fuse burned and STR is shorted when i change it it burned and shorted again ?

If STR is found damaged, you should check all the assciated components with it; like resistors, zener diodes etc: before replacing a new STR. All such components should be checked individually [out from the circuit]. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Can not get surround sound to work

Your Protection System probaly come on for some reason,Sony Is Known for that problem, Check on your screen if a red lit warning Staying (protect) Is on.If there is, Try hiting the reciever on the sides or the top of the cover fairly hard when it is turned on, Some times this will work to turn the protect light back off, Sony is bad for there amps end recievers going into the protect mode,

PROTECT shows every time I turn my reciever on. It's a SONY model #STR-DE335

Turn it OFF. Look for shorted speaker wires or shorted speakers.

None found? Disconnect all speaker wires and try to turn it on.

Turns on ok? One of the speakers/cable pairs is shorted. Check them again.

No good? It's dead. take it to a tech.

The word Protected shows up on the reciever! I tried to clean out the bad grease on the Volume control. The remote got so sluggfsh it would hardly move.

Protected is usually the unit has partially shut down to prevent further damage or burning up. The high power amplifier section is shorted or the speaker wires are shorting, including speakers. The speaker wires can be checked and eliminated as a problem, where frayed wires are touching the other terminal or a bad shorted speaker. If all external short have been eliminated, a technician would have to fix internal short.

Sony STR-D715 Protect Mode

Hello,
This is a common problem...
It is in fact a bad power-amp module.
I have repaired quite a few of these receivers by replacing it.
The module is inexpensive. I Googled the Part number and found several sources for it.

Good luck!

Sony STR DE 197 Reciever with No Sound

I have the same unit. My best recommendation would be to remove all speaker wiring, and try new wiring with another pr of speakers,since the "outdoor " speakers were rained on. the protect mode that the unit went into sounds like it did because the speaker outputs were shorted due to the rain, so ensure that the speaker output terminals are not shorted and dry...also see if output is still availalable at the headphone jack...if it is, the pre-amp section is still good , in which case the protect mode and no volume output out of the speaker jacks may mean that youve blown the ouput trasnsistor finals.
I hope this helps.

Sony DE-445 reciever flashes PROTECT

Sounds like a grounding problem. If the ground plug isn't missing or loose try plugging it into a different outlet.

check/replace your speaker wires. If a wire came loose, it will go into "protect" mode and shut down, to protect from a short circuit.
