The problem is with the micro processor on the back of the fx-1169a board (gm-p420ug) this is the board the inputs connect to . yours may be a diffrent p/n due to yours bein a "e" extention model. to repair this problem you need to remove the processor from the socket, remove the socket from the board and solder the processor onto the board. the processor is ic002 on the back side the problem is thermal in nature due to cold solder joints on the socket. i have fixed this problem many times by using this method.

This is card problem, you need to replace the card- FX 1170 A. Apparently I have been told that it's worth $1000. Please check. Harish

Link ASUS laptop to Sharp Aquos LCD TV


No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

I have an older 2004 or so philips hdtv projection tv with the built in tv stand. i want to connect my HD cable box but there are no hdmi ports. and i buy a wire with the VGA on one end and hdmi on the...


Get a component video cable (blue, green, red) and a separate RCA audio cable (white and red) if your cable box has a component video output and the TV has a component video input.

If your cable box doesn't have the component output, you will need a converter to go from the HDMI to component video. Something like this: http://www.hdtvsupply.com/hdmi-to-component.html . There are other converters available if your TV has some other inputs available.

A cable that has an HDMI M on one end and a VGA M on the other will not work. HDMI signals from the set top box are a digital signal. The VGA port on the TV is set to read an RGB analog signal. (Similarly a component to VGA cable would not work since the RGB and PbPrY are not compatible.)

I hope this helps.

How to turn on rgb from lap top to tv.


In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

Im trying to connect my sega dreamcast which has red white an yellow av cable only, however my insignia NS-32E570A11 led tv only has for component connection with the blue green n red, when i hooked it up,...


Sorry, this will not be easy....

You need to locate a composite to RGB converter box.

Your Sega outputs a composite signal - Video (yellow) and audio left/right (white/red).

The TV needs RGB (red/green/blue) inputs on the component connection...your composite signal divided by three. There are converter boxes out there for around 70 bucks or so.

Are you certain you do not have a yellow VIDEO IN jack on your set? Every LCD and LED TV I have experience with has at least one.

How do i get 1080i, my tv shows im only in 480i. i think i might have it hooked up incorrect. my other tv of another brand is much newer so all i did was connect the hdmi cable from the tv to the cable box...


Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

Im trying to connect my unit to my tv to record shows and i having trouble doing so please help i am hooking it up wrong


For OTA or CATV signals, you need to daisy chain the coax from the source (antenna for OTA) to the coax input on DVD recorder and then the coax out to the coax input of the TV. If you have a set-top cable box with an incoming CATV signal, it should be connected between the DVD recorder and the TV.

The unit can tune in and record 480i (SD) ATSC (OTA digital), NTSC (OTA analog), analog CATV and digital CATV channels.

A satellite receiver or a non-CATV cable box should get the incoming signal first and then have their composite video output (A/V) connected to the DVD recorder composite video input and then their coax (RF) output (if present) gets connected to the TV. For these, you would record from the IN1 or IN2 (press Select Input) instead of selecting a channel. Then connect the composite video out on the recorder to the TV's composite video in.

Digital signals are either enough to tune in or give no signal. So check that your antenna is correctly oriented for OTA.

Separately, you can connect the video signal when playing DVDs via composite (good signal) out and component out (better signal) out to the TV's matching input. For the component video, the sound is carried on a separate cable. Then set the TV to the input source.

In the case of wanting to watch a VHS tape while taping to a DVD, do not use the Component video source, set the TV to Input 1 (composite).

I hope this helps.

Hooking up my Sony HD Tv


Couple of items come to mind.
In the menu of the receiver, is there a way to choose video and RGB?
Set the receiver to SAT
Connect the HD Cable Box to SAT
Check the TV is on Monitor RGB.
Check the input being used by the monitor RGB cables is selected on the TV.
Have a picture? NO, receiver has issues.
Yes? Do this with each input to confirm they work.
You can reset the whole receiver to factory by holding the tone button down and holding the standby button for three seconds. (This clears your speaker setups, too.)
