When I plug in samsung tv, power indicator lights up, but tv doesn't turn on after pressing power button. caps seem in good shape


A power supply is more tann just caps. And a capacitor can be defect, without any visible signs. As a electronic repair engineer (already retired) I can tell you it is not even easy for me to do a good diagnose, when I have a TV on my bench. I use service manuals and measurement tools to chech where the error is, before I can solve it. Can be a bad soldering, lose contact burned IC bad diode, broken wire, to name sustain a few things you could find. I think it would be wise to ask a tech to do the repairs for you, but before arrange a max price, because tv's are becoming so cheap it is almost impossible to repair on, for less then the price of a new one.

Serial port remote control between Sony models


The problem you will have by keeping the serial port is; all the new products will no longer have serial ports.
You should replace the serial port with wireless or dvi .

Go into the settings menu of the projector and turn off the auto source function, then select the input that you are using.

if using a laptop you may have to simultaneously press your FN and relevant 'F' key to send the signal out to the projector. The 'F' key usually has an image of two side by side monitors or it says LCD/CRT. Wait a few seconds each time for the signal to be sent to the projector. Sometimes you may have to repeat this action 3 times to get the image on both your laptop and your projector.

good luck

Canon LV-S3 how to check hours on the lamp? do I have to have unit hooked up to an input source?


Lamp Replace Counter
Be sure to reset the lamp replace counter after Lamp Assembly is replaced. When the lamp replace counter is reset, the LAMP REPLACE Indicator stops lighting.
Note : Do not reset the Lamp Replace Counter until after the projection lamp is replaced.
1. Turn projector on, press MENU button to display the On-Screen Menu. Press Point left or right button(s) to move the red frame pointer to the Setting Menu icon.
2. Press Point down button to move the red frame pointer to "Lamp counter reset" and then press SET button. The message " Lamp replace counter reset? " is displayed.
Move the pointer to [Yes] and then press SET button.
3. Another confirmation dialog box appears and select [Yes] to
reset the lamp replace counter.
Note : Do not reset the Lamp Replace Counter until after the projection lamp is replaced.
This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard.
 Lamp life may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their life in a shorter period of time than other similar lamps.
 If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR lights up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down.
( Follow carefully the instructions in the LAMP REPLACEMENT section of this manual. ) Continuous use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.
 A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in which the projector and
lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector's AC plug from the AC outlet immediately. Contact an authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that
there are no broken shards or pieces of glass around the projector or coming out from the cooling air circulation holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the projector
except those who are authorized trained technicians and who are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to do so, may result in an
accident or injury caused by pieces of broken glass.

Sharp XG-E650UB LCD Projector


Absolutely, they are designed to do so. You will need a svideo cable for video if your laptop doesn't have a parallel port for external monitor. Most projectors have svideo and parallel ports to use them as monitors. If using the external monitor option you select the alt/enter buttons to display on projector.
