My sisters TV picture keeps shrinking to about half size, and after atime comes back to fullsize. I do not know the make. Other TVs in the house are OK. Could this be expensive to fix? Thanks, R.L.

    Thanks, Dan,, it is an ordinary tube TV, I think it is a job for a professional.



    If it is expensive, then a new TV! RL35MEG.

I can only provide a [possible solution here without the make and model, but from your description I'd guess that there are poor solder connections at or around the vertical IC. I am assuming that this is a CRT based projection set. Other types will have different solutions. If you can solder and you are comfortable working inside the set (there are high voltages present even when unplugged), you should be able to fix this yourself. Locate the vertical IC (usually a small flat IC attached to a heatsink) and resolder the pins. If that fails to resolve the problem, try replacing the IC.

Update this with the make and model along with any progress.

Thanks,
Dan

Regular picture size shrinks and color fades


This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video. You can get complete parts and instructions from www.TvRepairKits.com

I have a Slim-View LXI TV Model # PTV 515 AHO1 Has no Picture


while i dont have a true answer, I can tell you its a magnavox tv sold by sears produced back in 93. Ours just started doing this last week. I couldnt find any help online so we replaced it with a new led flat panel. WOW what a difference, the LXI was great for the past 17 years but the new tvs are better. We put the LXI in the garage because we couldnt throw it away. That tv was like a family member, if i figure out how to fix it i will post the how to.

TV screen shrinking from top to bottom.


My Dearest, j30;

It sounds like you have a problem in the 9 volt circuit which feeds the vertical output ciruit; CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
This is not a repair that a novice should try, but if you call a factory authorized service center and have them come out and give you an estimate; AND tell them what the problem is, you will look know what you are talking about!

60" Projection - Screen shrinks down then back up


 
I had the exact same problem. The screen would shrink then expand. After thrity minutes it would correct itself. Then one day it just broke - no sound and no video. I searched these forums but did not find clear instructions on how to fix it. I gave up and called in a repair tech. He fixed my TV in less than 30 minutes.  To help others like me I documented the fix and created a step by quide and repair kit to fix the problem. You can find it here. http://www.magnavoxhelp.com

After power on TV the screen shrinks to (50%) and then back out to (100%) back and forth for about 15 minutes


the quetion is:  have you checked your format/aspect settings? if it is on auto-format, picture size will vary due to program you are watching.....or is it a raster/width problem? The thing about the time on digital clocks: daylite saving time usually started last saturday, the federal goverment changed it, the fall back time is now this saturday! Most newer digital clocks auto-change according to old schedule....( not sure if you were aware of this )  let us know whether a width problem or what......
