Is it analog or digital?


If it is a standard CRT TV unit it will be analogue only. If you want it to display a picture from a digital signal you will need to buy and connect a digital set top box to the TV. The set top box then picks up the digital channels through the antenna and displays the picture on the TV set. You will need the basic connections on the back of the TV to be able to connect a set top box and many older TVs do not have them..

Pictures shrinks.. Panasonic TC-20LM Television


Shrinking picture is a voltage regulation problem in the switch mode power supply, Possibly a cap used in the feedback circuit. Or an over current condition on the B+. This is a very tech intense repair because there is no magic bullet. If it is shrinking on bright scenes then you can bet it is a regulation problem, bright scenes draw more current from the power supply causing this effect. I would not suspect the horiz output because the regulation for this circuit usually comes from the main switch mode power supply. One diagnostic is to monitor the B+ going to the horizontal output and see if it fluctuates. If so you can bet it is a cap or optical coupler in the switch mode circuit.

We bought a 20" analog/digital tv the analog channels come on fine but we it scans for the digital channels it says no siginal will we be able to watch it when the change takes place even though we can't...


This could be caused by two different issues.
  • Digital signal reception is bad. The digital signal must be locked in, digital signal reception is either on or off (not like analog signal reception where you can receive a low signal and a fuzzy picture). You may need to adjust you antenna direction and height or obstructions around your antenna, reference the web site for your specific location (address) for antenna compass headings. http://www.antennaweb.org/aw/Address.aspx
  • Television is faulty, digital receiver is bad. Your new television has two receivers, an analog receiver and a digital receiver. A simple power surge will knock out your digital receiver. Make sure you have a quality surge suppressor connected to the television power and the antenna is properly grounded. Return the television for a replacement and purchase a quality surge suppressor.
You must add a quality surge suppressor to your digital television! http://ezinearticles.com/?Power-Protection-in-the-Home-Theater---Use-of-Surge-Suppressors-to-Guard-Expensive-Electronic-Gear&id=41318

Good luck.

Hi: When you say small horizontal screen, ¿Do you mean picture does not fill the screen completely from top to button? ¿Do images display normally though they are smaller in size? ¿Is color and definition of signal OK? Please answer so I can have a better picture of the problem.

Picture Shrinks


It is in the power supply or I would guess most likly in the horizontal sweep section of the tV set. MOST of the time, if the power supply is going lower in voltage, the set will shrink in width,BUT will also shrink in vertical size. If this is not happening, then I would say it is in the horizontal drive circuit. This is not a circuit a user should be experimenting with, as this is the HIGH VOLTAGE circuit and can pack a mean punch! Please if the sets less the 4 to 5 years old you may want to concider an estimate or replacing the set. Its all up to you. GOOD LUCK
