This set uses what is called a "Hyper" board; it processes all signal from all inputs.

These sets have a history of tiny capacitors on that board failing, called surface mounted that dry out and fail.

The classic pattern when this problem happens is the period until it clears up gradually gets longer and longer.

The board is no longer available and only available if removed and sent out for repair.

Probably not worth doing as the last one I saw cost over 200 for a repair/rebuild.

I do not like giving bad news but this is what you have.

Power light flashing green to red


Assuming the "squiggle line" is the Utility LED the unit has proper power. The light is steady green and not flashing, correct?

Have you reset the unit?

Try removing all but one attached device to verify it's not an overload condition.

A photo of the control panel would help.

I'm getting vertical lines on the screen half way down until it warms up


When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

Start up problem


Bill;

Cause 1
1. VERTICAL ROLLING, VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE, ALSO MAY HAVE HORIZONTAL PULLING OR TEARING. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB.

2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
Replace all these if they look bad or not. If you can't do it yourself call a service Company and get an estimate, it should cost about $450 if they know what they are doing.
Thanks using FixYa, Big Irish.

My sound comes on and the picture does not right


This could be a vertical deflection problem waiting to happen. Have the vertical IC replaced on this unit...
Seen this problem before, also have a technician check the IK kineing Bias circuits, could also be cold solder joints that do not make contact until the televisons warms up.

Didn't see the original question or follow-up, but the answer is no -- If the hyper module is failing and causing the wavy or line squiggles it will be apparent on ALL outputs to some degree and continue to get worse until the high ESR (equivilent series resistance) of those failing caps cause the chip sets to eventually fail then it will be nearly impossible to repair the module.

Poor and incomplete image until warm up


Does it shrink vertically as it warms up? could be a bad capacitor in the vertical circuit.
