Weird TV the audio is perfect, but the screen vertically squeezes to about a quarter of an inch and stays horizontally regular. it makes it impossible to watch but can still hear whats going on.

Hi. 1/4 screen. Horizontal or vertical ? Makes an important difference. I need more details, like typenumber f.i. Also, you must be able to carry out repairs on this electronic circuitry. Otherwise it makes no sense talking about components etc.

Sound like your Y-Sustain board has one foot in the grave. The Y upper buffer and Y lower buffer boards go when the Y Sus Goes too...

i think your vertical IC ( if vertical lines are shown) / horizontal IC ( if horizontal lines are shown) of your monitor has damaged. you may contact a mechanic and change the corresponding IC

Check the horizontal trafo output voltage,the capacitors and the power supply voltage (135-155V dif.the tube diameter).

REPLACE VERICAL OUTPUT IC ' LA7838

This is nearly impossible to diagnose via the Web. It sounds like the logic board is at fault, but not necessarily.

Hello Barbara76,
Is this a Horizontal line (inch or two) across the screen, if so
the fault could be either a faulty Vertical IC,Faulty Electrolytic
capacitors or just simple dry joints.

Hi,
If you have intermittent line horizontally across both tv screens then there is likely to be bad solder connections on the vertical ic's of both of them. This can be fixed by taking the back off with quarter inch nut driver and carefully sliding the chassis out and turning it up to see the solder side. I don't know the location numbers but the vertical ic will be mounted on a metal heat sink and the connections will be in a row. Sometimes you can see the bad connections. You may need a magnifying glass. I recommend someone who has experience soldering electronic circuits. No solder bridges etc. This is for intermittent (works sometimes) problem on vertical ic. If the line stays then the chip ic is bad along with a 1 ohm resistor off the flyback high voltage transformer. From what you described you likely have bad connections. Hope this helps

you have a problem in your vertical circuit i would recomend taking it to your local shop rca's can be real tricky to fix.
