RCA, rear prjetion, 46" tv,no power, ticking sound

The tv is model # p46720lvlg2 and chassis # is ptk169pka.
If i hold down the power button the green light blinks and when i let go of it nothing happens.but When i go to the back of the tv there is a ticking noise coming out around the flyback and a transformer when i hold the power down not sure where it is exactly.
Iv had 2 years of electronic training. But its been about 3 or 4 years since iv done any work on electronics and im a bit out of practices.
I did do some research before asking. what i have found is its ether the flyback or horizontal output transistor and the blue caps. Im not sure witch it is or if its something else.

or if at all possible to get a new board would be better yet

Ticking is usually related to the horizontal output and the flyback with the flyback being more suspect. If you need more assistance please let me know

Have Hd 1080 series tv model # vs-50111 tv will not turn on. When you try to turn it on green light stays on for 3 seconds then nothing.


it may or may not have the self check but try this:

When green light comes on and goes off ON THE FRONT OF THE SET press and hold the menu and input buttons at same time for 5 seconds or more and release both.

Power light should blink a two digit error code like 2 blinks, 2 blinks and pause--repeat it several times--all their sets after 1999 have this feature.

If yours does not someone has to go inside and measure voltages etc to find problem---a lot of the older ones develop broken solder connections and the chassis would have to be examined for that.

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

Sharp aquos 45 inch tv power light blinking


Please let me know if you can get any sound at all out of your unit.

I had a similar problem. I had a 52" RCArear projection tv. It would do this when I initially turned on the television, but then after a few "on/off, on/off, on/off" cycles it would stay on. Eventually it started doing it more; until finally there was a spark and that was it. The tv was dead.The bloggers called it "the blinking green light of death" (because of green light on the panel).The power board is going out.ALSO holding down the Input and Menu buttons afterward will give you some diagnostic information via 2 sets of blinking indicator lights.

You may very well have issues with capacitors on this set being that it is or very similar to the V26 chassis. Since I have spare test lamps laying around, I would normally try that first. If the lamp still would not stay lit, I would then suspect the electrical chassis (capacitors). When I suspect the chassis, I can usually verify it by pulling it out and partially disassemble it and find blown capacitors

The tv was working fine. Pressing the button to turn it on only turns it on briefly (sound but no picture) then it turns off. The standby/timer light blinks six times repeatedly.

No picture or sound mitsubishi 62525


Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.
