When this monitor shut down it made a loud noise thru the
speakers. This this did not happen but once or twice a day
but I had to get up and turn it back on with the front power switch. Today I turned it on and it clicked 2 times
(power relay) but no pic or sound. I took the front off
and blew out a lot of dust. Took off the back and looked
I saw no burned or exces heat signs the two ceramic resisters (15k ohm were very hot to the touch.
I could see the input selections on screen like ch 13
sat vcr ect different colors. I tried unpluging ect.
It seems to power up but no pic or sound from game, satellite or antenna. Then it would cut off to stanby.
same problem. Worked last night. Had a power outage (tv is plugged into quality surge protector) and not today it turns on, but stays in standby mode.same problem. Worked last night.

Getting the parts needed and repairing this monitor would probably not be cost effective. If nothing happens when you try to turn it on (i.e. no lights or LEDs come on) then it probably is the power suppley circuitry that is failing. If you are technically capable, you could remove the covers and look for a blown capacitor (the loud bang sounds like a capacitor).
I had a noise like that once in a full size van it turned out to be the ball joints onthe passenger side might want to get them checked it could have been fatal for us
maybe just poor speakers.....had a similar problem with an old sony. Replaced the speakers twice and always had a noticeable buzzing. Try running external speakers (computer speakers will work) at low volume to see if you hear it in those. If so, you may have sound board issue.
check in your manual and follow instructions on updating the software. you download the file to computer then move it to a memory stick (USB), then simply insert it into the tv
Try checking your speaker impedance. If you have 6 ohm or 8 ohm speakers make sure the impedence matches. On the front panel hold down button that says "straight effect" while pressing Stanby/On button, it will default to SP IMP 8 min, press straight effect again, if you have 6 ohm speakers, then press Standby again to exit setting. Also, double check your speaker wires to make sure they are all connected, and none are loose.
Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.
I've had that same problem before. What was happening is one of my amps safety cut off usually a built in surge protector basically, was coming on thus the loud thump. Most of the time when it comes on the amp goes off. Could be a power issue as well. Have your alternator checked too. Once your car is started it is run by your altenator so it could not being supply enough power. I fixed my problem by adding two 1 fared capacitor, one for each amp I was running.
The output section has smoked and requires repair. The unit is not in "protect" mode. This means that the outputs are turned off to prevent additional damage to either the amp or the speakers. Expect a repair to run from $15-$40 in parts plus the local labor rate.
