    Thats a power supply issue, as the set isnt going into shutdown you may possibly need a new deflection (D Board) which has all the power supply and deflection supplies on that one board.

    They are no longer available at panasonic, so a remanufactured one is the only option which is just as good as a new one. The company I get me manufactured boards from is at the following link theyre fully guaranteed and they give credit for your dud board. You can leave them a email with the model number and they respond quickly with prices.Heres the link.

The color goes out on my panasonic PT-47WX49E TV.


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

I Have green squiggle lines that are moving around on the screen. I can minimize the lines by darkening the picture and toning down the color which makes the picture too dark. Any idea what is causing this...

Panasonic 53" tv


Blue background lines with colors otherwise OK may be a loose or dirty blur drive potentiometer on small circuit board behind front grille and beneath front imerboard cover. These are hot-glued in place from factory but may be the cause f the problem. They're VERY sensitive.

If you have bowed blue lines instead of properly aligned colors, you probably have a blown convergence amplifier IC. These boards are no longer available so yours will have to be repaired. Some shops repair them but many send them out for 6-10 weeks. Fairly expensive too considering the amplifier chips are about $35 each (x2).

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

there will be 2 convergence ICs that you can access from the front. take the grill off in front(screws behind door and on side in back of tv)and take the panel off. then the board right in the front with the black heat sinks is the convergence power board. take the board out or position it comfortably and replace the 2 large ICs(stk392-110) and any burnt resistors you can see. after fininshed check alignment in the regular tv menu.

Panasonic PT-47WX53 does not turn on


Yes, I did try to use the power button on the TV itself. That did not work too. Yes, there is blinking red light too. I searched through several sights and found out that it is an issue with the IC 4511. I could not find a place to buy the chip.


By the way, our local TV dealer asked for $400 to fix this issue. I had already spent $400 on a different repair on this TV, 6 months ago.

Any suggestion/advice would be very helpful. Thank you again for your response.

3 green spots on the top center of my projection hd tv


I had a similar problem and brought it in to a technician for a quote of $860 to fix. The problem - speck of dust on the optics. If it weren't under warranty I would take it apart and blow off the dust myself.
