55 in Hisense has no picture, red start up light blinks three times when try to power on

SOURCE: philips tv blinking red light

Hello,

I've seen this problem before with Philips. 6X3X blink was the X-sus or Y-sus boards. In other words, the TV cannot make the picture on the screen properly, so it won't even try and will shut down.

I've also had difficulty getting these parts from Philips (even while being an authorized service center). If you have an authorized service center near you, you might want to give them a try because I don't believe they were too expensive, just hard to get.

I hope this helps you...

Your problem is your thermal fuse.It is located around the bottom of the compartment that houses the lamp. You will have to remove the lamp and take the bottom back panel off. Then you will have to remove the fan. I ordered the thermal fuse so I would know what I was looking for when I started to replace it. If you take your time and are patient enough you can fix it yourself. I fixed mine and it's working great.GOOD LUCK!!!

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to.

I do not think it needs replacement, rather some defective capacitors are 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.

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.

Good luck.

SOURCE: When TV is turned on,

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

• No video, Power light is on or blinking.
• TV is making a clicking noise.
• TV takes a while to come on
• Screen is very dim or flickers.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
