Because D953 and D954 go dim right away indicates a short in th +27v and -27v line. The most likely suspects are IK04, IK05 (convergence output IC1s). The other suspect is I601(vertical output chip)

The power, hdd led and reset switch pins are at the bottom right hand corner of the motherboard near the BIOS battery.

The connections are fairly easy to plug up to but not knowing what case you have or the connector plugs i'm going to give you a link to download the manual for this motherboard.

Just click on the link below and when the page has loaded up click on the "Downloads" tab and download the manual. The information you need is in section 12 under the header "Front Panel Connector"

Bottom of TV lights up but dims and get brighter and dims

If you buying from ebay it's very possible for this model TV to have two power boards that are defective as it has a history of LED issues that damage the power board, a lot of sellers on ebay get broken screen TVs and remove the boards and sell them without testing or having any idea how a TV works, send both back you bought on ebay at the sellers expense if they were guaranteed working. has a kit with both the supply and new LED's that will be tested and work, this set uses a couple different LED strips that aren't interchangeable, make sure you match correctly

It's not the main board, tcon board or panel, slim chance of it being the power board (5%), it's your LED backlights that have failed, new strips can be ordered from shopjimmy, I'd stay away from ebay for parts

Hitachi LE55A6R9A has sound but no picture. Passes flashlight test. No LED backlights appear visible at all. Trying to determine whether to start replacing boards or LED strips first.

The led driver may be on the main board or on it's own board. Led strips don't fail all at once so if you had a dark area of the picture then I'd suspect a led strip. TV Parts Universal TV Stands DLP Chips ShopJimmy This is the place to get parts.

My Hitachi tv will not turn on

My Hitachi used to eat Horizontal output transitors. I do not even know if your uinit has that anymore, but if that goes out the unit wont make the B+ voltage needed to power up the unit.

I have an LG 47LN522-UB LED TV that stopped working after three years and need help diagnosing a problem with it.

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. To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
