Question about Philips 42PF9996 42 in. HD-Ready LCD Television

Phillips 42" LCD Mod#42PF722OA/37

I purchased four of these TVs on the same day at costco. It was October 06'. The first one went out in November 07' (just out of warranty) Contacted Phillips they said it was most likely a power supply problem. The repairs are over $800.00 only paid $1200.00 for the damn TV. So I went and just bought a Visio for $997.00. Now all four of the Phillips have gone out with exactly the same problem (but phillips will tell you it's rare). Turn on power hear a click, green light comes on, then begins flashing red. Has anyone yet to find a solution for this or should someone form a website to file against Phillips this is rediculous. FYI these were purchase for my corporate office coference rooms.

This problem is related to two failures, one is the Power Supply Board, another one is the Y-Main Board. Troubleshoot procedures:

1. Disconnect the Vs Power Supply cable from the Power Supply Board,
2. Turn on the tv and check the Vs voltage on Power Supply Board,
3. If the Vs voltage is there, then the Y-Main board failed.
4. If the Vs is not there, then the Power Supply Board failed.

Philips 42PFL7422D/37 42-Inch 1080p LCD HDTV Picture went out but still have sound. Any tips on how to fix it?

If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

The *audio cuts out occasionally on my 42 INCH Toshiba flat screen TV Model # 42RV530U. Unit purchased from COSTCO on August 21, 2008. * Audio 'dead spots' (missing several words) in conversations every...

Try using the Audio line out RCA jacks feeding a PC powered speakers to see if it does the same thing, If it is OK, then the problem will be in the power amp sections that drive the speakers.

I need screws for an Olevia LT37HVS tv stand

Most of these sets us either a M4 or M6, around 22mm. this is close to a 2" long 1/4-20 screw, but in metric.

Home depot or radio shack, or just about any place that sells TVs these days ought to have them.

At radio shack, a wall mount comes with the following screws to fit all TVs:

  • 4 x Phillips screw (M4 x 10 mm)
  • 4 x Phillips screw (M4 x 20 mm)
  • 4 x Phillips screw (M6 x 12 mm)
  • 4 x Phillips screw (M6 x 20 mm)
  • 4 x Phillips screw (M6 x 30 mm)
  • 5 x Phillips screw (M5 x 6 mm)
Only caveat is don't go with a screw substantially longer than what is needed.

3 light x-lines across TV screen

From elsewhere on the web:

"Proscan used to be the RCA high-end trademark; RCA (at least the TVs) was purchased by Thomson; they leased the proscan name to a Korean outfit that has the TVs made in China.
I've never owned a Proscan (post RCA)... but the internet buzz is that they are of inferior quality and that it's virtually impossible to get support in the USA. I would qualify that: Costco is selling Proscan TVs; they extend the warranty by one year (to two years); and if you have a problem, ya got Costco behind you. So I guess unless you buy one at Costco, you should pass"

Perhaps you need to contact the entity at which you purchased the television.

Green screen vizio lcd

My 37" vizio I bought in Dec 2007 did this (green screen at start-up on all inputs). At first it went away by itself after you left the unit on for 15 minutes, but then 2 days later the whole thing DIED. Luckily Costco has a 90 day return policy on TVs.

Vizio tech support suggested this (before it died that is):
Please try to reset all setting and then to see if the problem is solved. 1. Press the Menu on your Remote Control;
2. choose Set up on the OSD;
3. then choose Reset All settings;
4. Press the Exit on your Remote Control to remove the OSD.
