    My tv picture shakes on cold start. After warming up a bit, the shaking stops. This problem started after I had to move the tv to install new carpeting; the tv was not dropped, shaken, or otherwise mishandled. This has been occuring for about a month; I noticed that it takes much longer now for the shaking to cease after startup. On warm startup, the tv shakes but hardly noticeable. TV has worked beautifully until now.

    I checked all the wiring; all hook-ups are correct.

    I refocused the image with the onboard matrix alignment sequence.

    Cable company repairman verified that service was not the problem.

    I have the same problem. It has progressively gotten worse. Is there a way I can adjust V-hold?

That problem is caused by defective capacitors on the Hyper Board location UZ01 stamped MVPU14. You will need to have a technican remove the board and replace all the 10 uF @ 16 Volt SMD caps p/n 24619040N found on that board. The Hyper board is no longer available as a part.

The problem has been there all the time, probably a dry solder joint or a bad chip, thats got worse over time & has now completly failed, its time for either a trip to the tv repair man, or the best option a nice new smart tv, i just bought a 42" for £199 why mess about.

The power comes on and then turns off and the front green power light blinks.


There is a small IC in the power supply section,
not the IC regulator that's the problem.
