RCA DLP not powering up - stuck in boot sequence

To a recent message, you responded with the following: "That chassis has had some issues with faulty capacitors on the power board which will cause the set not to complete the boot sequence. If you need additional info please let me know." I am having the same problem with my RCA Scenium HD50LPW165 DLP. Can you share a possible solution beyond purchasing a new power board? Thanks weschue@swbell.net

    No, when I plug the TV in to the power line, the POWER LED and the backlight behind the MENU buttons light up. The power supply fan also starts. Nothing beyond this happens. I have tried unpluging and reconnecting. The first service man replaced the lamp, but this had no effect. His next guess was to replace a $500 circuit board, but I do not want to invest almost $1000 into a 3 year old DLP. I am capable of replacing components on circuit boards. I work with surface mount components frequently. Thank you for your assistance.

    Your model is the ATC322 chassis , The capacitor issue was for the ATC336. However the same capacitors may be at fault on yours. Does the led flash 5 times?

SOURCE: RCA R52WH74 (ITC222A Chassis)

no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.

Hi Jdvillanueva, I have a Mitsubishi 52525.


Hi Mark,

First of all I would like to thank you for consulting Fixya.com regarding on your problem.

Your model no. Mitsubishi WD-52525 (Chassis No. V26) is known for steady blinking Timer LED fault after pressing the power button key. Once this kind of symptoms is encountered and the unit didn't come on and stuck to this blinking death of life, it means that the DM board failed to boot up. In normal operation, timer will blink after AC is applied for 80 secs (DM board booting process) maximum before the picture and sound to come on.

You've mentioned that you had already reset the unit, unplug and plug back in to the outlet but still the symptoms persist, then this is a clear indication of DM board malfunction. It will not stop from blinking if the faulty parts didn't isoltated.

Good news! because I have a link where you can buy a repair kit for this kind of fault. Kit includes the parts that are known to be faulty, instructions that will guide you in the whole process of repair. Click it HERE. It is a V26 chassis (your chassis) DLP / DM Power repair kit.

For additional info watch some tutorial video below.




Electrolytic capacitor info. (Known to be faulty on the symptoms you've encountered)

Please let me know if you need further assistance.
Rating and feedback are highly appreciated.

Hope I helped you.

Have a nice day!

Are you Sure that the computer model is Dell Optiplex GX260? Because looking at the manual diagnostic lights are found at the back. and the fault can be determine If the ABCD lights are yellow or green. But None the less 2/3 Depicts a hard drive problem while 3/4 depicts a memory issue.

Hard drive Issue:

1. Disconnect all non essential cables at the back of the computer. Leave only the mouse, monitor and keyboard. See if it boots up normally
2. If it boot up fine. try plugging one peripheral at a time until you find which peripheral causes the computer not to POST (Power on Self Test)
3. If you still getting problems, Follow these steps
4. To access the BIOS you must tap F2 or delete key upon turning the computer on
5. Try to look for the Hard drive if it is detected by BIOS if not got to step 9
6. Look for Boot Sequence or anything that is associated Boot
7. The Order boot of must be 1st: DVD Drive, 2nd: Hard drive, 3rd: Network etc.
8. Save the changes and Restart
9. If you still get the same message I suggest that you take out the hard drive and put it back in until it is detected in BIOS
10. If Step 9 did not work I think you need to replace the Hard drive

Memory Issue:

1. Open the chassis of the computer
2. Try taking out all memory modules
3. Rub the metal contacts of all memory with a pencil eraser
4. If more than one memory. Put one memory first and turn the computer on. If it turned on add another memory and turn the computer on. Repeat these steps until you determine which memory is faulty or all memory module contacts needs cleaning

Iphone lock button doesn't work (not responding to clicks)


Can I ask if you have the following issues:
- Power button will not lock screen - When resetting the phone you see the apple logo for a few seconds then it resets again and goes into a loop - iPhone will turn boot when connected to a computer - when it boots up, the slide to power off screen appears - no amount of restoring fixes the issue
If so, then your issue is the power button is sticking. I fixed this last night by opening up the iPhone and cleaning out the Power button.

Normal sequence is the power led should blink 5 times then shutoff when power is pressed. If the led stays lit the DM is suspect. You will need to have the DM trouble shooted to determine whats preventing normal boot sequence from completeing. If you need further assistance. please let me know.
Your chassis is the ATC322

RCA DLP TV


That is either the flyback auto transformer or the relay getting energized. I reckon it is some issue with these, or a failing power board. Best get a technician to look at it, as some spot inspection and testing will be required to isolate the faulty components.
