These trouble is commonly caused by a weak solder or loosed wire connection, try to check the soldered parts at the main pcb if there is some weak connection then try to solder, but be sure not to connect separated pin, loosed connection or wire connector try to remove the connector then return it in the same position but be sure to remember the location of each connector or try to use a pen to mark the connectors.

I have a white line in my TV screen


could be as simple as a bad HDMI cable or a bad connection on the LCD screen to system board cable this is internal so harder to repair. It may be a bad LCD screen, which is not really repairable as spares are hard to find (no two alike) and expensive as a new TV.

Samsung smart tv picture is only in top left corner


Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

IH252 inc monitor bottom half darker than top.


Thin screen LCD monitor brightness controls operate several fluorescent lamps called "backlights" that are positioned behind the LCD display. Typically, they're located around the edges of the screen - sometimes just at the top and bottom, and other times at the left and right edges and others still at all 4 edges.

Fluorescent "backlight" lamp, inverter & connection wiring.

The lamps are miniature versions of those sold in stores. They require a support circuitry called an inverter that convert & boosts the level of DC to AC voltage performing the functions of a ballast in a traditional fluorescent fixture.

The reason a part of your screen remains dark is because one or more of the components in the picture above has failed and will not allow the lamp to shine. Replacement lamps and inverters aren't expensive - but requires patience and the ability to disassemble / assemble the monitor (which is usually harder to do than it appears) and solder. They are available various lengths and color temperatures (you must get a lamp that is identical or it will be noticed). If this is a new monitor - you ought to return it for replacement. If used, consider the cost of purchasing a replacement (new or used) vs. repair.

I hope this helps & good luck!

Why is my TV picture dim


Hello David
It sounds that the back light inverter board, and back light CCFL lamps to your TV need to be checked. It will be best to contact any service technician, because to check its back light CCFL lamps, you must disassemble the display panel, a very skilled work indeed. If you are sound in electronics, you can check it. If you wish to know more http://electronicshelponline.blogspot.com/ check this link. It has details. Pull up older posts there by its left side bar, or see it in 'Timeslide' option.

Pioneer pdp-6010 plasma popped loudly screen went blank flashing red light in lower left corner. will not come back on after unplugging/replugging just a flashing red light. brand new unit


Blew a transformer in the set. REATURN IT IF YOU CAN. Return it for the same tv. Pioneer makes the best plasmas in the world. This still cant contribute for the product of mass production. Defects will always arise in the best mass produced items in the world. If you cant return it then use the store warranty you will hope you purchased if you were a foold and didnt purchase it well then try to **** with the manuf. warranty. But by all means if you can return this tv to the store and only accept a new in the box model. Keep this in mind it does not hurt the stores budgets to return and exchange for the same item. The defective item goes for repair and gets to be resold again. So all stores will honor this with no trouble providing. #1 You are within the return policy. and most importantly #2 you dont buy from circuit city. If you did be wary of your warranty becuase the company just filed for Bankruptcy and they may not be in the position to honor that warranty soon. So if you guys have purchased something from circuit city that that has a warratny and you are within 30 days RETURN it and buy the same thing form the competior that you can forsee being in business for the next 3 years. All major competitors will price match so you wont have to spend a dollar more in most cirmcustances
