Question about Samsung SPN4235 42 in. Plasma HDTV

1 Answer

No pic For a while there is a random rectangle thta pops up at top of screen, large from side to side. It contains random pattern of lines. Turning tv off and back fixes this- until today. After turn off & on, flashes of color (every 0.5 seconds in the same pattern every time) are running across screen. Turned off and waited 1 hr and now now picture at all, only a very small randomly placed orange dot is visable. Audio is OK. Any ideas?

My Vizio TV has dark spot top left corner


Hi Brandon,
I am afraid that the dark spot in the screen is not repairable. Manage as long as you can or go for a new tv.

Picture goes black with gray fuzzy lines ~ 1/2" apart horizontal.


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

Vizio 42" LCD - Random appearance of small black rectangles


There is a processing fault that is starting to occure. What you are seeing is a type of aliasing. This can be in the main signal processing or in one of the control areas.

The set will require service. The service rep will test the set by using board substitution. There are typicaly a number of areas in the TV set that can cause this type of fault. Once the defective board is located the fault will be easy to service with a simple board swap and some adjustments.

If the set is out of warranty, it may be expensive to service. With many of the no-name brands, spare parts can be difficult or impossible to have.

Vizio 42" LCD - Random appearance of small black rectangles


I would check and see if you have the text option on under your closed captioning. With the new digital transition the signal for text captioning has been getting messed up during broadcast here lately. If it is on i would just shut it off or go to regular closed captioning.
