Question about Mitsubishi WD-52525 52" Rear Projection HDTV

2 Answers

Blue flickering light, no audio

I've removed the back panel on the TV in order to access the power supply and check the capacitors. How do I remove the power supply? Is it all one unit? Does the entire bottom left section come out together? I'd appreciate any help. After reading where others had the same problem, I'd like to check the capacitors and see if that's a problem before taking to a technician.

You will need the service manual in order to get that chassis out. once out it is an easy repair to replace the capacitors yourself. I just did one the other day.

My tv just popped shot blue sparks and smoked a little? Power supply? No power light.


Yes. It must be from its main power supply regulator section. Might be due to burned backlight inverter transformer at the back light inverter board. It is an other chance. Check it.

This trouble caused by weak dc output voltage. Try to check your power supply it is located at back of your tv, try to remove the back cover of your tv and follow the ac cord there you will see the power supply then try to observed the capacitors if their is a swollen or leaky capacitors you will notice it that the bottom of the capacitor has a wet mark or an oil spill if you notice something like that, try to replace it with the same value. But be very careful,observe the polarity of the capacitor.

WHEN THE TV IS PLUGGED IN AND TURNED ON IT FLICKERS IS THIS A POWER SUPPLY ISSUE AND IF SO WHAT IS THE SERIAL FOR THE POWER SUPPLY


The flickering you describe is most certainly a bad capacitor in the power supply. find a hobbiest or TV tech to do this for you. These TVs require lots of patience to remove the back cover and removing the power supplies. Good luck and thanks for asking.

Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care .......

How do I access the circuit board on the Apex LD1919?


All the components are screwed to the back of the cabinet. Once the back screws are removed, the front bezel snaps off. (Not easily, but take courage and try.) Release a connector in a set of leads to the pilot light panel to get enough slack to lay the bezel flat. The LCD panel then removes with seven silver screws (one is a ground lead). Move it to the side, and the power supply board is accessible. Two connectors and four screws, and it comes out.

Blinking light on 37" Dynex LCD


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Vx800 flickers when cold


I have repaired several Viewsonic VX800 monitors. The symptoms include a power light that flickers or flashed on and off or a screen that flashes on briefly or stays off. The problem is bad electrolytic capacitors on the power supply board. These bad capacitors do not look bad and do not swell but they do develop a high ESR (Equivalent Series Resistance). You need a ESR meter to check them. But if you have these problems, you should assume the capacitors are bad and just go ahead and replace them.
First you must open the monitor and gain access to the power supply board.
1. Remove the stand: It is held with 6 screws on the back. Also on the back are 2 black screws that must also be removed.
2. Remove the button bar from the front, bottom: It is pried off. This will expose the 2 screws holding the front plastic bezel.
3. Remove the silver plastic bezel from the front: First remove the 2 screws holding it, then you can pry the rest off. This will expose the 2 screws holding the screen to the plastic back.
4. Remove the screen and electronics from the plastic back: Remove the 2 screws holding it. The 2 speakers are glued to the plastic case. Cut the glue with a knife. The screen and electronics and speakers should lift out of the plastic back.
5. Remove the metal cover to expose the electronics: There are 2 screws holding the VGA connector and 2 screws holding the DMI connector. There are 9 screws holding the cover. These must all be removed. There is a black plastic sheet glued to the lower edge of the cover. It must be lifted. The cover should now come off.
6. Replace the bad capacitors. The power supply and signal processor are on the same board. It is marked VG800-2. The bad capacitors are surfaced mounted 100UF 25V. The bad capacitors are CM16, CM17, CM2 and CM165. The two most critical are CM16 and CM17, but they all read high ESR, so I just replace them all as long as I have them exposed.
Reassemble in reverse order.
