A dead Viewcom LCD computer monitor. Model WZ005S12-D

A customer brought three of these LCD computer monitors to my shop. All three LCD screens had the same problem. Shutting down, no screen display and the stand light was flashing.
Usually, when I see a stand by light flashing and no screen display, I know this was a power supply problem and it should be an easy fix. I opened the cover of one of the three LCD screens and soon enough I saw seven capacitors that were bulged. I opened the other two monitors and all of them had the same problem with the same exact bulged capacitors.
The power supply was a separate board than the inverter board. It was an old LCD computer screen. I took the power board out of the screen and replaced all the bad capacitors in the power supply. With the ESR meter, I checked the other capacitors on both boards the inverter and the power supply and all of them checked ok.
The bad capacitors were: two 1000UF/16 volts, two 1000UF/25 volts, one 470UF/25 volts and two 220UF/35 volts. The moment I replaced all of these bad capacitors on the three LCD screens, all three of them came to life. I was an easy fix and good income.
To me it was strange since I got all three LCD screen and all of them has the same exact problem and the same exact bulged capacitors. The job was done fast and easy and I was happy about it.

Dark and blurry Sony KDL-40W2000

-+ Dark and blurry Sony KDL-40W2000

Dark and blurry on the left side, the image has lines and distorted ghost images
The unit is 3 years in service.
This problem occurs while watching all different devices hooked to this television: (DVD player, cable, satellite, game counsel, etc.)
When I push gently on the top left corner the set works fine for seconds.
With this small movement, I don’t need to check the inverter nor CCFL .
What I face is a LCD panel that has failed, this is a very common problem with these new LCD televisions and there is no way to fix it. The part price is always more than a new television.
Fortunately this kind of faults, I already have met with in several notebooks lcd, and managed to fix some ones.
The set works now fine, but for how much time? This is the question!
As you can notice on the image(1) the set is repaired on 26 Sep. at 19:54 local time (GMT).
until now (7 Oct.) the customer is glad.
If the problem occurs again I coud then update you.
In this repair, I proceeded as follows:
First See how to dismantle the set here:
Then the images shows the fault before and after repair.

Recently i repaired a NEC TV 21 CRT and this is the story that how i have fixed this issue.
The sound of this tv was not stable. Sometime good and other time not. After i opened the tv first i checked the speaker (tv is off) the label of speaker indicated that the speaker must be 8 ohm. My ohmmeter confirmed this, when the sound of tv got problem and speaker is ok the most problematic part could be the sound ic amplifier. Since i did not find any diagram for this i asked which ic is sound ic?
