If the volume button on the TV itself is doing this, I recommend taking it to a TV repair technician considering this will require knowledge of the internal mechanics. There are several causes for this however the most common is corrosion and broken linkages inside of the panel.If you're refering to your remote itself - there are ways to help these issues:After removing the batteries - Using a phillips screwdriver, you can remove the mounting screws and open up the remote (may have to pry it open gently with a flathead or soft tool) . Underneath the top (where the rubber buttons extrude), there should be a flimsy sillicone sheet which connects to the board underneath. Thoroughly clean it with q-tip and rubbing alcohol to extract anything that may have spilled inside crossing connections or debris (dust, etc..).Usually, this solves the most common button issues.

Hi Scott,May I know if the unit stuck to green blinking led at the front panel and the unit won't come on?Jdvillanueva

you tube it! always helps

When you unplug the set it then when powered up waits for the DM unit to boot up----the green light blinks on the front for about 70 seconds and when it goes out the set can be turned on.If this is the case I have a suggestion, let me know if I have described the situation correctly.SD TECH

Tools needed: Phillips screwdriver 1.Turn the television off and un plug the AC cord.2.Remove the front speaker grillby gently pulling on each side. The grill will snap out.3. Using a phillips screwdriver, remove the three screws (one on the left and two on the righ tside)that hold the recessed plastic cover in place .4. Remove the plastic cove rand set aside with the screws.5.After removing the cover,you will be able to see the lamp cartridge .With the screwdriver,loosen the three screws of the cartridge. The three screws will not completely remove.6.Gently grasp the metal handle and pul lstraight out (towards you).7.Insert the new lamp cartridge securely into the TV. Do not touch the glass surface of the cartridge.8.With the screwdriver ,tighten the screws on the lamp cartridge.

FMT pwb or the light engine either can cause the same symptom

That symptom is almost always caused by bad capacitors that are known to fail through ou the five circuits boards within the chassis. Usually the DM board and The Power Board caps fail which can cause the non stop blinking timer led. You can get the V26 Chassis DM / Power repair kit from www.tvrepairworld.com which has the caps with repair instructions that will often repair that issue.

Press the Menu and the Device/input buttons both in together and see if the led blinks the two digit code of three blinks pause then followed by four blinks then it repeats the 34 blink several times. If so then the V26 Chassis power repair kit from www.tvrepairworld.com will usually solve that issue. The kit contains the replacement capacitors and the CD with repair instructions.

The optical block is going out. You will notice more dots coming untill the screen is full of them replaceing the optical block will be quite costly over 400.00

are you talking about Test points on the power supply?? the capacitors tend to dry out after heat and time and will be less expensive than the board? you can measure a an ohmmeter to confirm.?

defective DM assembly

Replace the front key board panel. You should be able to get one at www.tvrepairworld.com just hit the contact button on the right and enter the model number and symptom they respond quickly.

most likely having a optical engine failure. the most expensive part of the tv no less. suggest having a tech go and evaluate.

Thats usually caused by failed capacitors on the DM and the Power boards most of the time. Its very famous for your model which is the V26 chassis. You can get the V26 Chassis DM / Power repair kit from www.tvrepairworld.com which has the caps for both boards and the CD with detailed repair instructions.

yes they dont always puff up on top. But check the ones on the power board there are two 2200 uf, two 3300uf, and foue 1000UF caps that are known to fail and can cause the blinking led also.

Take it apart and clean the dried water spots off. Its hard to say if it will work but that's the first thing I would try.

Clean it

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Something for you to try, it will not hurt the set.

With the original Mitsubishi remote and the set on hit Menu, 1,2,3, enter to do a soft restore on your set.
