When I turn on my tv it may at times have a white screen-then it goes dark and eventually the picture will come back, its been happening more and more lately.


The lamp only has a life span of about 8000 hours if you are past that then it maybe time to replace. If you average out 6 to 8 hours a day X 365 x years you will get the average hours used, not sure how old you set is but the formula works.

Power but no picture


the Y-SUS BOARD is for picture in tv.if the picture is not coming or not proper the Y-SUS board needs replacing .but if the picture is blurry or with linings reparing helps.but in your case the tv does not turns on with y-sus board connected only error led comes on.this means y-sus board needs replacement.
you can get it from www.partstore.com
---------
if you are not familiar with replacing the y-sus board its advisable to get it done by local tv repair technician familiar with your brand/model.

This will help. Thanks please keep updated.please do rate the solution if helped.thank you for using fixya.

Picture (video) jumps from bright to dim


I figured it out myself. R243 was intermittently open. Replaced it, and now we can watch the Super Bowl.

TV picture scrambled and getting worse


This can be a fault in the tuner, IF, or primary part of the video processing. With age and use some of the parts, and especialy capacitors, in these sets can become thermo sensitive and unstable.

To service these types of faults can be very time consuming. On top of this would be the cost of the parts.

Considering the age and type of set that you have, I would suggest that it is time to be looking for a new set.

Wavy Screen on Startup


I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes. The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.
