Samsung DLP HLP4663W

First you called a very inexperienced tech. Call a Samsung Pro.
Someone will have to examine it.
Get your money back for the ballast, call Samasung and get a real Tech to help you.

This sounds like bad solder connections on the circuit board. Call a good TV Tech to repair this problem unless you have knowledge of soldering circiut boards.

I have the same problem, it is called the "bow tie" effect, I read in a forum a couple of years back it is because they started computer sodering instead via humans and it was not successful during that time. I bought mine in 02. I was hoping to find a picture of the the board and the specific soder joint on this forum. I hate to pay alot for a tech, (specially since it was mitsibitsi's poor craftmanship) and a 65" is not something you throw in the truck and take to them. Good Luck.

Hourglass shape on left and right side-ballpark repair price please

The shape your seeing is called 'V Bow' and 'Pincushion' which needs to be calibrated again. Theres probably a diode that went out. The tech can open it up and adjust the angles back. I wouldn't charge over $100-$150. Shop around for a good repair tech. Good Luck poe_diddley.

Weird shaped picture

You have whats called a pincussion problem. Its not or should'nt be a major repair, but unless your an experienced tech, Its not the type of repair you should attempt to do. Call a pro. Good Luck

Continuous low whistling or thin buzzing noise

The high pitched sound is an indication that theres a short most likly in the Hi voltage sweep section or power supply and with out the proper training you should not even take off the back as there are no user replaceable parts inside of these sets. All the parts are soldered in and you can not look at them and see that they are bad.. its almost like when your check engine light comes on you look but what do you see without a computer to read the on board computer vto see what the problem(s) are. Take the set into or call a pro to assist you with this repair. good luck

No picture

Something in the power supply sounds like it popped. Like a capacitor? These sets the whole board is made to replace. But theres alot of techs who fix these boards and charge alot of money, but in the long run unless its a common problem it dosent pay for the board to be fixed. An example is a tech will charge 65 an hour for labor. It take almost two hours to fix board and 2 weeks to get parts. Pickup and delivery is 75 bucks. service call is 50 bucks. The whole rebuilt board is 140 bucks. + inhome labor at 50 bucks and no long wait to get set back. And the entire board has a 90 day warrantte not just what the tech fixed. Good Luck

Mitsubishi Big screen

This problem could be as simple as dirt or dust inside on the lens of the picture tubes or on the mirrors inside the projection tv. It could also be the blue tube is on its way out or the focus on the blue tube needs alighnment . This set has extremly high voltage inside, so its not for the do-it your selfer to mess with!! Now theres nothing wrong with a do-it your selfer but in this case save a life, and call a tech in to see if it just needs cleaning or light alighnment. If you call one, watch how they take apart the screen assy. from the tv and see how they clean the set ,so you can do it next time. Now like I said it could be a picture tube going bad too so please dont be too disapointed when they tell ya that. But depending on how old the set is ?? It might be worth investing in the set?? Also another thing , when the tech comes in they MAY say the set needs to go to the shop to be looked at . This is a way to get more cash out of ya as Ive seen simple cleaning or adjustment repairs turn into 500 to 700 bucks when in reality, it could have been done in the home for a hundred or so. Dont be afraid to pay someone a hundred or two, if they fix a broken set in the home, as believe me you saved a bundle when you let them, cause when it goes out the door (the set) tack on an extra 200 at least. Good luck
