Question about Sharp DVHR300U 109-Hours Video Recorder

1 Answer

Sharp tv 59DS 05H

I have a subject tv that has lost its remote control input due to a burst of high power RF from a defective transmitter (I think) The result is that it will not respond to the remote and I want to over-ride the remote control to switch the set on and off on the wall switch. Anyone know how this might be done please? The circuit board is a mystrey as nothing seems to be marked in a way that I can find my way around the circuit for powering up. Thanks in advance gentlemen. Gwalia

Unplug TV, take off the back. One each board there will be capacitors. the tops are flat unless one has blown then it is bubbled up. If you find one that is bad, copy the number and search the internet for a replacement. Unsolder and remove the old one ( there is a line drawn on the negative leg, mark the neg side on the motherboard so you can replace the new one the same way). Now solder the new one back onto the board. This worked for my TV, hope it helps

SOURCE: lost access to control SHARP TV

Unplug your unit and plug it back in after 2 minutes. When you plug it back in, try to use the remote to turn it on and see what happens. Good luck to you

SOURCE: tv will not start after power surge

Voltage checking and caps inspection will be the first thing to do.
If you can post the pictures, that will help a lot. Look at the inverter board to see if you are getting 12~18vdc feeding it, also look for caps with leaking/bulging top.
See some pictures here:

My rc939 wont work unless right next to receiver.

Your description sounds similar to the problem ceiling fan owners have with their RF remotes. Try disconnecting the power to the pool light (at the breaker), pausing, and reconnecting power. Try remote operation. If nothing changes, reprogram the transmitter to the original setting and repeat the previous test. If nothing changes, the transmitter may have sharply reduced power output or the receiver may be defective.

2008 HHR Remote Starter not working

Is this an issue with all 2008 HHR remotes??? Highly doubtful , probably the vehicles keyless entry system . Taking the vehicle to a qualified repair shop an having the keyless entry system checked for DTC'S - diagnostic trouble code's . Do you know what a DTC is ?
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the body control module (BCM) to remotely activate certain vehicle features. Keyless entry will lock/unlock the doors, or release the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message to the BCM. A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:
• Door locks
• Liftgate lock
• Remote rear doors (Panel only)
• Vehicle locator/panic alarm
• Illuminated entry lamps
• Remote vehicle start
The keyless entry system has the following components:
• Keyless entry transmitters
• Keyless entry antenna
• 2 Way Advanced Remote Start RCDLR

Guessing will not fix this .

Direct TV remote "tv input" button won't work with my Sony TV

I came across this looking for a similar solution for my Samsung TV, and I found the solution on Apparently after you program the remote for your TV you have to hold mute and select again until it flashes twice then put in 960 to make the remote control TV input too. Note you're remote should be in TV mode while you do this. It seems silly that the DirectTV guy wouldn't do this when programming the remote.

Hunter fan with remote control was 3 speed, now only 2 speed

It sounds like fan motor is okay. There are two motor windings -- one low speed, one medium speed. Low winding gives you low speed, medium winding gives you medium speed, both windings give you high speed -- so I would say if you get high speed, both windings are good.

The remote (the hand held transmitter) controls the speed by raising and lowering the frequency of the current which is 60 cycle coming to the fan ceiling box. If the fan speed -selector switch (usually a pull switch) is set to high, when the remote (transmitter) signals the receiver to change speeds, the frequency of the current is changed by the receiver (the receiver is usually in the fan housing).

Sounds like you'll need to replace the remote system -- these come in sets, both transmitter and receiver, and cost about $30. If you're not experienced with wiring fans, you should get an electrician to do the job.

You need the original remote controller to be able to switch input modes.Universal ones usually don't work. If you don't have the original remote and can't find it ever or if it is too expensive you can buy an rf modulator ( very cheap) and connect your dvd player, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me. It placed the connection to channel 4 and other cable channels are still working,

You need the original remote controller to be able to switch input modes.Universal ones usually don't work. If youdon't have the original remote and can't find it ever then the only way to reachyour tv is through coaxial antenna port. Soyou can buy an rf modulator ( very cheap) and connect your red yellowand white cables (rca cables from a dvd, game consoleetc) to the modulator then connect the modulator to your antenna with acoax cable. This worked for me. It placed the connection to channel 4and other channels are still working,
