You probably have a component breaking down on one of the circuit boards. It would have to be checked out to find out which one. Stargazer

No picture, no menu, black screen, no raster, sound ok

From your detailed description, it sounds that the main chroma processor IC has damaged. Raster means nothing, but the lighted screen that appears, when a TV is switched ON. For some brands, there will be a blue screen; when there is no signal input, and some others will have a bright white screen with some snow.
I advice you to contact any service technician, to get this TV repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

My RCA console tv has white horizontal lines accross screen, picture is very light and sound is ok, very frustrating. I know its an old tv, but appreciate any response. Thanks

Cold solder joints on the flyback transformer circuit board - probably because RCA used feed-thru steel rivets on their boards. Re-solder the connections using a good solder flux for clean solder joints and this will fix prob. The joints with the dull, pitted finish are the problem joints.

Visual transparent lines at top of picture

You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

It needs repair.
If the line is vertical, then something is damaged on its horizontal circuit section on the mainboard.
If the line is horizontal, the vertical circuit section is damaged.
have it repaired to a qualified service center or person!
avoid switching it to avoid further damage on other parts!

Philips 27PT6441 27" TV Problem


Pls note that my experience is with the phillips 27" model27PT6341/07. It may not be the same board as yr model, as I can't remember nor find the service manual anymore. (browse around online for it though)

However, after taking the back off. Look close to the rca jack and svideo connection. Mine is located about an inch from the svideo connection.

Here are some pics that may help you.

The new one is the black and gold one marked 10uf 100v in the pic.
Other users have advised to go as high as 10uf 250v, to avoid having the cap overload again.

PS. I had the lines for about 2 weeks. They got steadily worse then one day my tv looked like it was broadcasting an hourglass. The lines converged in the center and flared outward (no pic).

Tv showing blue screen with flyback lines sound ok

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket

White line horizontially through middle of picture

A repair like this is in the vertical drive/output section of the TV set. It could be a simple capacitor causeing this problem or a combination of the capacitor and the output IC. A repair like this should not exceed 120 to 150 US. Is it worth that to you? How much can you replace it for? Good Luck PS please dont forget to rate this thread.
