Coppell TV Repair LLC offers you a REPLACEMENT SET for the backlight inverter boards used in Digital Lifestyles' LT42322 LCD TV.
When either of those fail - and it is only a matter of time before they do -the TV would power on with sound (if on the right input/channel), but the display will be black.
The set consists of two brand new master and slave boards as shown on the picture below.
They are not the same boards as the ones in your TV. They are an aftermarket replacement , which is fully compatible and possibly better than the originals.
(Do not believe vendors who claim theirs are better unless they've been on the market long enough to actually backup such a claim.
The original inverters started failing around 2011 and earlier in 2012 those new replacements became available...it won't be a few years before we know if they live longer or not.)
The new boards are slightly larger in size and you will need to either bend the edges of the aluminium shield cover of the original inverters or remove them altogether.
Both approaches will end up with functional TV and both have their pros and cons so it is hard to advise on what to do. If it was us we would keep the shields, but so many of the newly manufactured LCD TVs come without them that you're practically upgrading your TV to today's [Chinese] standards as you keep pulling parts out of them...
No other parts or purchases should be necessary. The set comes with a flat ribbon cable needed to connect the two boards. Do not attempt to use the cable from your original inverters.
If your set has a flex connection cable between the master inverter board and the T-Con (the LCD controller) then you will not be using that with the new inverters. You will not notice a difference and you will not lose quality.
On another note, the LT42322 is also know to have problems with its power board...so before changing the inverters it is a good idea to make sure the power board is outputting the 24 volts the inverters need to work. It's a simple test and we strongly recommend reading our article on testing the TOM277CABB power supply board before placing an order for new inverters.
We - Coppell TV Repair LLC - specialize in LCD and plasma TV repairs and we have fixed hundreds if not thousands of such boards - locally and through Internet.
Last , but not least, you can choose to self-repair your old boards or , if you buy this set, you may want to send them to us as opposed to throwing them out. We will cover your shipping costs and , depending on the supply and price dynamics, pay you something.
Those are brand new parts and we have no reason to doubt their functionality, so we are not testing them indvidually.
In case of DOA issues you are covered by the standard warranty conditions.
The default shipping option for the kit is via USPS First Class Mail, which is slower and less reliable. Envelopes are light and fragile and there is a greater risk for the letter contents.
WE STRONGLY RECOMMEND THAT YOU CHOOSE THE PRIORITY MAIL OPTION DURING CHECKOUT.
WE DO NOT BENEFIT FROM IT - THE PRICE IS WHAT THE USPS CHARGES FOR IT, WITHOUT ANY ADDED VALUE TO US!
YOU ARE THE ONE THAT BENEFITS MOST, BUT YOU SHOULD MAKE THAT CHOICE!
PLEASE DO NOT HOLD US RESPONSIBLE FOR WHAT USPS DOES!
