Question about Sony 42XBR900 Television

1 Answer


I turned on my TV (KE-42XBR900) yesterday and after a few seconds, it automatically turned off. Right after the TV shuts off, the standby timer light on the TV / Plasma screen flashes 6 times and the red light on the base unit flashes 9 times. What could be the problem?

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).

Tv will not turn .....replaced lamp about a month ago worked fine until yesterday, green light blinks and then shuts down

Ask for a repair man to open and check it. There might be a problem on the circuit that the system detects and automatically shuts off to avoid further damage.

RCA DLP Model # M50WH74S Problem: Replaced blown lamp, when plugging it into AC, blue LED lights up right away for 2 or 3 seconds, then shuts off. Waited for a few seconds, and relay will click on and...

The blue led dies because the power source dies: it detects a big short on one of its outputs and shuts down to protect itself automatically. Since apparently it's a very big short and you just had to replace the bulb then the faulty part is the ballast board (the one that powers the bulb): when the bulb failed it has generated a power surge that fried it.
Replace the ballast and verify the power source board: if you're really unlucky when the ballast got fried it has in turn damaged the power board.

TV displays RGB code and then displays, no signal and then shuts off. What does the RGB code mean?

It means the source is not set correctly. Switch the source to input 0 (cable or antenna depending on your particular set up).

Will lead you to the manual and quick start information if you need more specific instruction.

Tv turns on for two seconds, shuts off, begins binking.

The problem is most likely a power supply related problem.
The TV is in protection mode right now. It's keeping the other parts inside the TV from being damaged by automatically turning itself OFF. The 9 blinks should be an error code for the problem with the power supply. I don't have the Service Manual for your TV model number to tell you what the code means and which part to replace. Every brand of TVs have a different meanings of the code.
If you have electronic experience, you can find a factory repair manual over the internet. Normally, it's called a Service Manual. It costs about less than $20.

My sony ke-mx42a1 shuts down and the stanby

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

I hope I shed some light on the subject for you.
