Top 20 Sony VPL CS5 Multimedia Projector Questions & Answers

Without seeing it I cannot be sure but it sounds like a failed pixel. That is not repairable.

What sort of a projector is it?

Are you connecting to a laptop or PC as it maybe a fault with your cable, try another one first.if this does not solve it you may have an issue with the internal main board or LCD.

Try replacing the cord that hooks to your device and transfers data

That could indicate the following-

1. The lamp cover or filter cover aren't properly closed. Try shutting the projector down> opening both covers> closing them> restart

2. The lamp is nearing the end of its life or is faulty and you'll need to replace it.

Have you tried the following:

Connect the power cord and turn the projector to standby mode.

Press the following keys on the remote commander in the following order for

less than five seconds each: RESET, <,>, ENTER.

did you change anything in the unit recently

Hi, Please check the power supply and fuse.

i hear that this is a common fault and that after a few minutes up to a few months they can just suddenly start working again if left plugged in... i have one which has just done the same thing i have taken it apart and checked everything minus the 10000 microchips... my advise would be check the main power board and see if the fuse is still good, the main power board is located in the front right of the projector and is a B!tc# to get at but if this is your problem it will have been worth doing. also be careful if you attempt this as there are alot of small connectors and ribbon cables... it is easily done if you know hat you are doing...

The internal fan ,that are to be checked.The fan should run.If the fan is not running then projector will turn on,then start but will shut off.This happens because the internal lamp housing and board.This two things gets overheated,as soon as you turn on the projector.So this fan this there inside to cool the lamp housing and the board.But if fan is either slow or not running then internal heat temperature increases and unit shuts off.Its common problem,this is to save internal board and lamp housing from getting overheated and short.In this case take the unit apart from its back,by re,moving the screws,then see the fan,if its very dirty then it has to be cleaned by the cleaning brush then check the fan wiring.If its ok,turn the unit on and see.If the fan is not at all running then its faulty fan,but if the fan is running but very slow then from the back apply any external table fan too,to the unit and then turn on the unit.In some cases,not in all.In some cases this has helped to make the projector work.In other cases the fan has to be replaced.------------ Also as you mentioned that Air filter is clean,still try cleaning the filter once before replacing the fan. To clean the air filter please perform the following steps: 1. Switch of the Projector and let it cool down 2. Disconnect the Projector from AC. 3. Remove the air filter cover. 4. Remove the air filter from the cover. 5. Wash the air filter with a mild detergent solution and dry it in a shaded place. 6. Reassemble the filter and the filter Cover. ----------- this should help.Thanks.Helpmech.

i would imagine it is having a capacitor overheating... i just had one with dry joints on the capacitor and it took 4 hours to start up...... hope this helps i would recommend taking it in to get it looked at if you want the projector...... also the capacitor which will be most likely causing this will be located on the main power board which is located in the front right hand side of the projector under the main display board which is held in place b y three screws... cheers hope this helps

Replacement of the lamp can be done as follows:
1. remove the power and keep the projector under a soft cloth.
2.There is small door with one philips head screw which will open the cover.
3. You will find the lamp with two screws which are marked . remove the two philips head screws and using the handle which can be taken out from a catch , pull slowly up. do not pull violently.
4. Clean before you put the new lamp into the slot, replace with the two screws after the lamp goes into the connector.
5. clean tthe filter after you remove the cover and set it back.
6. Switch on and use the menu to reset the lamp timer.
You are now ready to use the projector but take care to keep in ventillation and clean the filters occasionaly.
Helpful I hope. Good day

You can not reset you have to take it Sony Service Center only they can do it

no power and after some months the power indicator comes on

Yes,get the unit fixed.

to clean the lamp: no chemicals, nothing abrasive. you can touch the outer glass (not with your fingers), but do not touch anythjing inside the bell. best thing to use is a microfiber cloth. your lamp is nearing or has passed 2000 hours of use. the projector is telling you to replace it before it blows (and sometimes shatters). after you replace it, reset the lamp timer (through the menu).

try to change your power cord if problem occur change power supply board.

canned air. blow it out.
