RCA Scenium D40W20 40" Rear Projection HDTV - Answered Questions & Fixed issues

we layed it down to insert the brackets

Try turning down your Red CRT.

It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. The noise is what gives it away. This happens so that no further damage, and possible fire will occur.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

Does the led blink

If this is a combo unit (TV with DVD built in) you need the original remote---Universals almost always are missing key features the original remote had as most companies have someone else make the unit and put their name on it.

Thanks for using FixYa and for the great rating.

no sound

do you see thin curved blue lines going from bottomto top of screen. If so its most likley a blue CRT drive board issue. If its a solid blue it could be a small signal board issue.

Hello
I can,t understand the fault of your TV with this short description. Will you please inform me some more details of the fault? What do you mean by this "image tears" and "inverted colour". Please give me some more explanations. OK.

You have bad grounds on the power board. The first place are the solder connections under neath the flyback transformer. This is my first area of inspections. You must really, really inspect the rest of the board. This TV has many poor solder connections too numerous to pin point. These are very small and will take an extremely close inspection. I cannot say enough here. Look for bad solder grounds on the vertical IC (do not use excess solder or you will short this IC). Look for solder connections on transistors, diodes, jumpers, power resistors and capacitors. Capacitors include electrolytic, disks and safety capacitors.Resolder other transformers too. Be sure to check close for bad solder connections on the heat sinks as well. Next, use an ESR meter to check all your electrolytic capacitors.This is a good place to start repairs. Thanks for asking and show a few hands of support!

If there is not one in back, it could have the old style DVI jack. You'll need a DVI to HDMI adaptor.

What is the Chassis number printed on back? ITC222? Are you sure its the FBT?
UED has Parts and boards for these sets, 1-800-648-6657 they should be able to give you correct part number.
AMCE for flyback Transfomers 1-800-575-9833

there is most likely a bad connection on the power board. i really suggest not letting it do that all night unplug the tv it can do alot of damage to the tv if it cycles like that for long periods of time.

could be a setting on your dig-cable box routing audio elsewhere try that hopefully its a simple solution to your problem good luck

the fact that you have color on menu. is an idication this will be a small signal board issue.

At the back... small door.. remove old bulb and replace it with new. It could be blown and it is protecting the rest of the TV
On google put: RCA D40W20 parts.
Near the top will be a site to go to and they will ship to you and it is easier than changing a home lightbulb

convergence is off, convergence ICs need to be replaced

Replace the small signal Board. You can get replacement boards from www.tvrepairworld.com

Most of the times, the power suppply board just have dead leakages gases capacitors.These capacitors alway bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get ur tv power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole rerfurbish power supply board for the replacement.

check AC cord, fuse, resistors in poer supply lines, rectifiers (diode), power regulator and horizontal output (transistor near flyback)
