I have an RCA RT2500 audio-video surround sound receiver about 10 years old. For the second time in its life, a power fluctuation has knocked it out of service. The standby light comes on, but no power to the system. It seems that I paid Radio Shack about $140 five years ago for the previous repair. Is this unit worth another similar expense? Dennis

Unfortunately, your question has too many variables. Try this. Unplug the unit. Plug it back in. When you first push the power button, you should immediately hear one mechanical click from the unit, followed by a second click with 5-10 seconds. If you don't hear the second click, the unit may have a condition known as DC Offset. It would be unusual to have DC Offset only within the first 5-10 minutes. It's possible that power supply has an issue where both the positive and negative voltages are not coming up at the same time.

I've owned this receiver since the Summer 2001 and it worked well until the audio became intermittent several years later. Eventually, the unit was ON but all sound was dead. It turns out that there are solder joints that developed tiny solder breaks. These were found in the main power board on the large electrolytic capacitors and on the 7 power tab transistors that share a large square heat sink. Thermal cycling can cause microscopic solder joint breaks over years of use. After I re-soldered the broken joints the unit worked properly and is still in use in 2017. Consult a qualified electronics repair technician for the repair, which can be accessed via the removable panel on the bottom of the cabinet. Of course, be sure the unit is unplugged from AC power before starting your inspection and repair.

if the receiver does not power on from standby there is a problem like bad power supply or even bad macroprocessor. You need to bring it to a service center for diagnosing. 10-years old receiver, maybe better to buy new one.

Take a clue from the 10-year old vintage of the TV and the two analog audio cables. It's Dolby Pro Logic Surround at best, not Dolby Surround in the modern, digital, multi-channel sense.

TV's are not the source nor the end of a multi-channel audio chain. Feed this thing a 2-channel source from a Cable Box (into the "TV" jacks), DVD, Video Tape or CD with proper Dolby Surround encoding and will seem to open up the sound field a bit and kick in a little surround effect. It can also simulate a Hall effect and Dolby 3 stereo.

It may be only some tired capacitors in the power supply; they can cause this kind of problem.
Parts are probably the lesser cost; you will need a tech with a little bit of gear to find the culprits.

Your FM tuner will only generate sound from the front sepakers. CD's, Tape, and I guess mp3 player, as well, will only play through the front speakers.
I've included a link for the manual. The audio on this rig is pretty complex. read through the info, especially pages 11,12,13, and play with the audio controls.

The dvd player is responsible for reading the surround sound track, and sending it to the receiver. First make sure you are playing the surround sound track on the dvd, many have a stereo track too. Next, try another dvd and see if you can play surround sound on that one. If you can't play surround on ANY dvd I would start looking at the audio connection from dvd to receiver. Are you using an optical cable? Red, white, and yellow RCA cables? Optical will transmit any sound over only one cable, RCA cables need one cable for each channel (LF, C, RF, LR, RR, sub.) If your connections are correct, is the receiver set to play a surround sound track? Is it set in 2 channel mode?

check fuse on the inside of the stereo.
