    I've got an Arae 40 “ LCD Model number ELT-4000 AP. No display but all other functions OK. I have had the inverter boards checked professionally with no fault found. I have checked the psu on all outputs and they all check ok.



    Only thing left I am told is the lamps, whats the best way to check them ? Do I need any special equipment (anything over a multi-meter defeats me).



    Thanks in advance.....

My screen was very dim on the left half and totally dark on the right half. I pulled the lamps and sure enough both the top & bottom lamps were half lit. On the Backlight Display Driver Board are two Electrolytic Capacitors 56uf @ 25v. I replaced both capacitors and lamps are now working properly! Total cost of parts, under two dollars.Solution # 5 was absolutely correct. Thanks!

Please do the following: when turn the unit on, Carefully see the screen response,i.e., any bright screen comes on then off? or never has any light in screen. If screen is bright and than off, it indicates that the backlight is faulty. In this case you need to replaced the panel or get back light fixed. Deshan_lu@thomas.com.au

What do you have hooked up to it? make sure there arent any special features on a DVD player (such as progressive scan) that your other components might have, but this TV doesn't

I've had mine fixed now. Spent nearly 2 months trying to get it sorted and had to eventually give up under pressure from the wife who was fed up of having the projector set up in the living room !!!

I used a local company who had it running in 2 days telling me it was a 'LCD controller board', whatever one of them is.

The most frequent problem in this set causing this symptom is one or more lamps failing in the backlight assy. If the set lights momentarily and then goes out, the backlight shutdown circuitry is detecting a bad lamp and shutting down the inverter that powers the baclight. Have a qualified service facility check the backlight assy for a failed lamp or inverter module. Good Luck. Joe Weibel Custom Electronics Memphis, TN 38133 (customelectronics.org)

SOURCE: screen changes between color as a demo function.no signal

Gateway was sued Class action over LCD's and Plasmas they sold over a 2 year period. They resell 3rd party TV's that were very faulty, an immature design.

Here's what I learned about mine, which makes it limp through as a Computer monitor (both DVI and VCA) and halfway functional TV.
You have to connect a DVI source, on the Main Menu for the DVI input there is an option called "Factory Mode". scroll down to it with the CH buttons and select it with the vol button. The scroll to "initialize eprom", select and confirm it. After the "Waitting" words disappear, make sure you have a TV source connected, Then turn the TV off and on, using the hard switch in the back. The TV input should be defaulted to channel 10 or 11 now But you select a TV channel that has no TV signal on it (like channel 1 for example) , the whole TV input side will refuse to let you select it again, and you'll have a blank screen and have to start over.

That takes care of the blank screen thing Now the other problem is parental control is defaulting to "ON" or something, and you can't program channels. With the TV input Main Menu engaged, select "Setup Menu." If you have this problem, then you'll only see 2 options, all the TV input and channel programming options will be missing. You have to select Parental Control, and when it prompts you for a password hit the volume > button 4 times (or just wait for a minute.) This should bring back your TV System and auto prgram/manual search options.

Unfortunately, my TV doesn;t remember these setting very well if I select cable, it does better if I select "AIr". But at least it funtions - kind of. If you switch to your computer input, you probably will have to switch the monitor off and on from the back panel again. Mine always starts up with the menu onscreen. All this might bve less trouble if you have a the remote, I don;t know where mine went after the last move.

Good luck, and hope this helps.

For the solutution repair of the Gateway Model GTW-L17M103 TV 1/2 lit screen - I was told by a local authorized Sanyo Flat Screen Repair shop that the lamp or bulb is going out and needs to be replaced.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. The question will be, is the part still available? Before paying a TV repair person $75+ to diagnose the problem, ask yourself if you're willing to pay $250 minimum to fix this particular set. Also keep in mind that most TVs that old have a very limited number of replacement parts still available. Normally it will cost at least $75 to have the set looked at by a repair shop (diagnostics). If the part needed to complete the repair isn't available, you won't get that money back.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here.

Please let me know if I can be of further assistance.

I actually bought the 5 year warranty when we purchased this new and it was still under warranty. Gateway is sending us a brand new TV. No need for me to try to fix this, but thanks to all involved.
