It sounds like you have done some research on this issue. My suggestion is that the power supply is supplying the dc voltages to the inverter boards it is just that the inverters are not working, it is suggested that you replace both the master and slave inverters at the same time, You might want to try using a flash light or other light source and shine on screen and then get up real close and see if you can make out the images, and if this enables you to see the images and it appears that everything is working except the back lights then I would feel comfortable replacing both inverter boards. Hope this helps.HID KITS.

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.left one is good and right is badarrows point to a number of real bad caps

First, the used screen will be more than $300 plus shipping, new is almost impossible to get.Second, you need to get the exact model number as printed on the sticker on the LCD panel since you will have to transfer all the boards from old TV to the new panel.Parts: www.interliquidparts.comI myself will not do it.

The Master and slave inverter panels are faulty and yes this may still be under warranty. If the inverter panels (placed at both sides of the LCD panel) have "Rev 1.2" printed down one end, then they need to be replaced with Rev 1.3 panels. This is a common fault and worth contacting the manufacturer about.

LCD inverter backlight board is out 42pfl7432d/37

I wouldn't unless you're sure they match the particular model. Each of them are different depending on size of set. This can be verified by seial number version(ya1b, ya3b, c and so on). If you were to try this you might fry the backlight, requiring a replacement panel. They supply different voltages........Please be careful, can be lethal, 1000vdc or more........Good success, Meder's Tv

If the firmware upgrade hasn't helped then the problem is hardware - a part is faulty. By your description it appears that the main processor is functioning erratically and this can be caused by:
- overheating - you will need to open the tv and clean the inside thoroughly.
- an unstable power supply - you must open the tv and check the power source, probably the filtering capacitors have aged/failed and the output voltage is way off the recommended value.
- the processor itself is dying - you will have to replace the mainboard. Unfortunately parts for your tv can only be found at authorised repair shops, or dealers, so you will gonna have to take your tv to one.

unless it's under extended or manufacturer warranty...not cost effective to replace. You can get it at partstore or shopjimmy.com if this is the case. Good success.....Meder's TV
