Question about Sampo Televison & Video

4 Answers

I have a 42" Sampo-PME42S6 plasma TV. Its been running perfect until yesterday when it started to show lines and picture degradation after approx 3 to 5 mins of running. I thought it was the cable box so I changed to a DVD player as the source, the same exact thing happens. Pls help.

Typically the symptoms you describe can be either poor connection of the connectors and cables or some parts that are starting to break down because of heat. If the set is no longer under warranty, start with opening up the back and reseating all of the cables and connectors. Be careful with the flat ribbon cables coming from the panel itself. Update this with your results. If needed, we can look further.

Change ur pIF you are saying that every thing is connected properly check your video cable it could be bad use a new one if that does not rectify your problem it is time to call in the tech you could be having problem in your video circuit but you did not mention if the screen light up with no picture but with sound or it does not light up blank with sound.however there could be two things 1 if the screen lightup with normal sound it could be a leaky ,open, or shorted, transistor or ic in the IF circuit.2 If the screen does not light up and has normal sound it could be a defective horizontal stage.so it is time you take the set to a tech for repairs.good luck.

Did you try to unplug the TV from the power outlet for about half day to let it reset itself and also to cool down the unit, and that should do the trick for this problem..

Hope that helps............

You can try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works.. this not work check the cable try yo use another pair of cables ,even this did solve your problem then you need contact the company if under warranty ,if its out of warranty then you need get service from local TV repair center....


Good luck..

2. Punch in a 3 digit code (provided below)

Hello experts I recently came into ownership of a Sampo pme42s6. it powers up fine and has audio, but none of the video inputs are allowing a picture. I plugged in an S-video and Analog VHS signal,...

i don't know how much the new one cost but it is fixable. Check the components around flyback transformer , check bad connections, check the flyback it self. It ask some expertise . If you can't ask help for your neighbor technician if he is good you will pay little money. but not less than $80

Samsung hpr4252x perfect picture in

You have a burn in problem from watching widescreen movies.If you have access to a signal generator or tv setup disc run a perfectly white screen on the plasma for about 30 min.This should help even out the pixels on the display.

Distorted picture on Sampo 42" monitor

This can occur due to many reasons...the simplest of those is...
Damaged monitor signal cable...results in improper signal transmission
Also check if ths is a problem with the monitor or VGA card...Just connect it to another computer...If it works then its VGA card problem otherwise its a monitor problem.If you are good in electronics then the problem is
1)You have the typical convergence failure of the convergence correction IC's which need to be replaced

2)Cpacitors on the CRT are damaged and need to be replaced..

If you are not familiar with electronics pls dont attempt a repair as it is a high voltage device and the risk of electric shock wil be high.Just drop into a service center if this is the case

"No Signal" floating notice on Blue Screen - No other picture

If all connections and the tuner have the same issue, you either have a power supply issue or a bad digital board.
