Proscan PS 50670

Hi,
11 years old Tv
Problem is: too often, I loose image and sound, lot of horizontal lines.
I have to shake cable at the back or knock hardly the side to recover both image and sound.... till the next time few minutes later!
Is it a cold soldering problem or anything else? Expensive to repair?
Thanks for your help!

Hi.. Mine is a sansui tv and I bought it 3 years back. Now it is showing a horizontal line on the screen. Sound is fine but I can't see the picture, I just see one white horizontal line on tv...


The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

My Sony trinitron tube Tv 36" seems to be going (its 10 years old


no ....the tube will end up after 20 yrs in 10 yr old sony...
it is worth if u fix it. randomly going black means...horizontal driver trans former is the problem..or any loose contact with the 110 volt supply to that transformer,,or any loose contact with line o/p transformer.. (horizontal driver transformer may be gone
then tv behaves like this) if any other parts gone tv wont come back.... there may be a loose contact call a service pro..

Distorted picture on my 32" Proscan TV...(about 15 years old)


The RCA GE sets have a problem with bad solder connections in the tuner unit which also causes numerous symptoms including poor regulation, no vertical deflection, low audio or dead set.

Pulling in from the sides is either poor regulation or a bad eeprom/solder join issue

Ps 27123 have sound, tuning etc only small horizontal color band


Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,

Proscan PS27123 TV Problem


just to be sure, is it vertical or horizontal? Anyway, if it is vertical, it could point out to the vertical Ic section or some loose contacts along the lines. If it is horizontal, it could be a filter capacitor along the horizontal Circuitry. Mark the high voltage capacitors along the high voltage sections.


regards,

chris

Vertical line picture


problem is caused by the loss of horizontal deflection signal. It is quite surprising that the entire unit is still working, since usually, a loss of H-Out will disable the entire set. Problem can be as simple as loose solder connection to a more complicated defective horizontal circuit. I would suggest havint it checked by a professional TV tech.

I'll bet you have vertical output IC with some pins not soldered. This IC ( integrated circuit) is a "chip" that makes the picture fill out from top to bottom. After a period of time heat will cause the pins to crack loose on the circuit board. You need to have a tech check it for you. Stargazer
