SOURCE: I was given a sharp Aquos lc-52D62u the power

That is 2006 model year, 52" is a very big screen, you have nothing to lose if you will try to fix it yourself but you can also sell parts on Ebay, especially the screen is worth A LOT OF MONEY!

SOURCE: No picture or sound/wont power up

Your mainboard is damaged, the mainboard is the one where you plug all the cables (component HDMI), it is really easy to replace, you only need to take special care with the screws.
1. remove all screws in the back.
2. unplugg all cables from mainboard.
3. remove all srews from mainboard and replace it.
4. put all screws back and then plug all cables again.
5. double check all mainboard cables are properly secured.
6. Test TV.
7. put the back cover and secure it with the screws.

8. Enjoy your TV again.

SOURCE: power up not likely

This could be anything, literally. My first guess would have been the power supply but you have eliminated that. The rest of the unit is really not serviceable by home owners and would be very difficult for someone without any training. About the only other checks you could make is to check all the fuses. All boards should have at least one and may have several, including some microfuses which are typically marked as Fxxx (where x is a number). Additionally look for charred components (resistors in particular) or burn marks on the board. Check for loose plugs in sockets on interconnection wiring. If everything checks OK you need a repair tech. Furthur troubleshooting can only be done by a competent repairman. It does not sound like the problem should cost all that much to repair in relation to the cost of the TV. Good luck.

SOURCE: Toshiba 26lv610u tv/dvd has no sound or picture

Yes if there is no clicking, then the power supply is usually faulty. However its difficult to tell if it has affected any other boards(like the main board) with out testing it. I would suggest that you take the assistance of a tech, have him test it to determine if its just power. If yes then you can get a new power board and replace it. Otherwise it may be wiser just to get a new tv. You can get a 26 inch tv for around 350-400$ now.

A pretty strong clicking noise on pass side. nothing loose. good brakes. Maybe the wheel bearings


something in the tyre? wheel bearing problems do not usually click unless there is something seriously wrong. JACK THAT WHEEL UP AND ROCK IT LEFT TO RIGHT, IF THERE IS PERCEPTIBLE FREE MOVEMENT HAVE IT SEEN TOO. tHERE MIGHT BE SOMETHING STUCK DOWN THERE. Have a look at the brake disk and pads also.
Does not sound like a wheel bearing issue

2yrs old. Went thru 3 sets of batteries to get 20 pictures. Dead again. What`s the story?


Sounds like you have a short in the wiring. This is repair shop stuff, or buy a new camera time. Usually, if it is a point and shoot , it is not worth sending for repair as you'll playas much as a new camera is worth. I would look for a new camera, personally. Good luck.

10-year-old 32" RCA PIP TV just blinked off one morning after about 30 minutes. It makes a continuous high pitch sound, and the on/off switch is completely unresponsive. I assume this is a picture tube and...


It's not the picture tube(especially if image was good b4 it went dead). The high pitch noise is the power supply whinning because it's shorted or overloaded. I just fixed one of these sets - replaced the horiz. o/p transistor and flyback estimate around $120.00-$160.00

TV won't power on


Your model doesnt have a bulb. It has 3 CRTs instead. Sounds like something minor in the start up voltages. thereby allowing the start up relay to click then other times the relay doesnt click. So its either standby or start up supplies where the fault is. You can get a manual here at this link and also free support to help you figure it out.
