Hitachi 50UX22B I just cleaned the mirror and the 3 projectors off and dusted everything off with a soft brush. I put everything back together and when anything is in white,Like writing or the tv guide menu on direct tv it is blurry. Can you give me some advice on what to do to fix this problem? Thank you. e-mail is [email protected] The picture is blurry you can see the pic. but the white in the pic. makes it blurry. hard to explain like a halo around the images.

Use a 1" paintbrush and a vacuum cleaner hose. Then use a compressed air can to clear the fins on the heatsink also with the suction. It is also better to remove the fan, clean the underside and then spray it with dry silicone spray.

The best way to clean dust from your PC fans and CPU cooler is to use compressed air. You can buy cans of compressed air from any electronics store or online. Before you start, make sure you turn off your PC and unplug it from the power source.

How to Clean Dust from PC Fans and CPU Cooler - LinkedIn

Hi, Cutting out after 5 minutes sounds like an overheat fault. On every projector will be a filter that is user serviceable - it will most likely be blocked up with lint. To Clean - locate the filter & remove carefully. gently brush the lint & dust off the surface of itusing a soft brush or vacuum cleaner on its lowest seting. Try not to puncture the filter element. reinstall.

Sounds like static electricity caused some damage somewhere...you never want to try to vacuum a TV or use a cloth or brush, only thing that is safe is air like is used to clean a keyboard...you damaged a board in the set, could be the main or tcon or both

Hello
To clean the lens and mirrors of your projection tv follow up please.

Unplug the TV from the power supply. Never undertake any type of repairs on electric equipment without first disconnecting from power. Take care in handling any electric parts, as some may contain a residual charge that can shock you.

Remove screws from the back cover and connection area of the TV. Be sure to put them in a safe place, or on a piece of paper with notations for where each one fits in the television

Gently remove the back cover. Locate the mirror and three projection "guns," as these are what you want to clean eventually

Use a camera lens cleaning cloth (or other very soft and gentle cloth) to clean the mirror and lens. Gently remove any other dust before closing the TV.

Replace the back cover and screws. Plug back in the power supply

Turn on the television. Check to see that everything works correctly and that your picture is now clearer

snap off the fron cover its pretty tight so kind of pull hard dont worry it wont break its just snaped on tightly, after uncrew 3 screws under the screen lift up and pull out screen there will be 2 wires attached to screen, unplug them to set screen to side. dust off the projectors with dry rag, then clean mirror with windex or any window cleaning product. u are done cleaning front of Toshiba, put everything back together, then unscrew the bottom back and vaccum any dust balls u will see inside T.V. u r now done! let me know how it went.

You could Start with just Cleaning Mirror and top of All 3 Tube Lenses remove Back and try cleaning out All dust and Dirt with Thin Paint Brush then Remove Front Top and Bottom Panels and then you can Clean Mirror and Top Of All 3 Tube Lenses Then Put Back Together and see what Kind Of Picture you have then! Turn Color Off on Menu See if you Have a Black and White Picture?

You dont it is a specialist job please take it to an autherised service center, it has high level UV from when turned on with covers removed do not risk it, as it can blind you.

usually you need to remove the speaker grille then you will notice a few screws in the lower screen frame remove thos screws then grab the screen frame and slide up wards to disengage the clips that hold the screen assembly on.

was it blurry before you cleaned?
you should use lens cleaner and a soft cloth on the lens.

Wow, You are asking for a complete disasemmbly. If this is necessary, you have to remove any screws you can find that are connected to the front panel. Usually they are in the top of the set ( you'll find them after removing the mirror panel and mirror ). I wouldn't remove any tubes as the tube convergence would have to be all reset and that would require a cross hair generator. I do hope this has helped in some way, but all I can do is send you my best wishes as I certainaly don't suggest disassembly if there is any other way. Good luck
