Hello The problem is with its backlight inverter board. there are some step-up transformeres [small ones] fitted on board. If any one's core bacome loose this fault will occur. Just open the TV and listen to which one makes hi-pitch noise. Replace it, if you can buy it from the electronic market at your town. In most cases, the inverter board needs replacement. This board can locate on the right or left side of the panel, fitted vertically. http://www.dataentryjobs.us/67948.html
As far as I recall, there is no adjustment. Typically the display area can be cleaned as smoke and dust collects on the plate. Remove the front panel and clean the inner surface of the plate. You may find that sufficient to resolve the problem. If not, then check the power supply for 5V and 12V. If the supply is low, the unit will still work properly, but the display can be dim.
Symptom: when you first turn it on, you can see a VERY little light but after 5 sec, you cannot see it anymore or for most of us, we started using a flash light. Here is the summaryof the solution and I know that it works because I fixed it today 3/16/2011, 30 minutes ago. As many pointed out that there is a "light" 12v - 14v in the back but there is NONE.How do I know? I listened and searched and there are NONE. The whole LCD in the front is air seal like a light bulb so it is a light bulb already.Also, you might see a little burn/gray smoke on the left hand side, don't worry about it because if the light comes on, it stills work but not enough power. If the LCD is broken, please don't try by the part and replace it because by the time you read this, the parts and labor cost as much as buying a new one (on eBay and not Best Buy).
Problem: in the middle of the unit near the back near the "surround sound back", there are 3 capacitor rated at (2 units) 35v 220uf 85'C and (1 unit) 50v 220uf 85'C. What Yamaha did wrong, base on my guess is that they put the 85'C too close to the heat sink. The heat causes the capacitor to slowly blown that is why you still get your power to the LCD but not enough.
Solution: remove the top, unscrew EVERYTHING in the back and there are about 20 ~ good luck. For those that don't have good memory, please take a picture. There are many plugs inside that you need to unplug before you can remove 1st layer (audio/ video input) 2nd player (HDMI and Optical input), the last layer you will see 3 capacitors that are kind of "blown" up (google "bad capacitors" pictures or video). Remove them then replace them, which you can Google this on tube and they should teach you how. It was very easy for me but then again, please don't try to do it if you cannot even change your car oil or build a computer because I believe that is the difficulty level.
solder iron: $9-$20 get it on eBay or radio shack
(2 units) 35v 220uf 105'C and (1 unit) 50v 220uf 105'C or what I got was (3 units) 50v 220uf 105'C
I keep the 220uf the same to be safe but increase the voltage and heat to increase the life of the capacitors.
Sometimes,you might press a "film mode" or "Dim"or "dimmer which will turn OFF the front panel display.Check that first from your manual. It happened a lot! If that is not the case,then you need A/V repair guy to order the part to fix it for you. solutiondoct
Whats wrong is a bad capacitor. This is why when you turn it on you see the display for a little while, then it start to fade away. Unless you have a wiring diagram for this unit and know how to solder, your going to have to take it in for repair. You can try to check every capacitor, but have you seen how many capacitors are in that baby!!!! I hope this help. Good luck!!
The display will dim for certain features that are not available for use in your current configuration or current operation.
For example; if you do not have an antenna plugged in then the selection for the tuner will be dimmed on the display.
