Sony KF50XBR800 Red Component not working

I just purchased this older (2003) Sony Grand Wega from a private seller. Anyway, when I tried to connect the red, green and blue components for HD, I get no red color. I know the red component isn't working because when I unplug the red component, the color doesn't change. I get blue and green color only. So, I am assuming I have to replace the component part?????? Does anyone know if that's going to be expensive to fix?? Or if I can just order the part from Sony and change it myself???????? I just think having someone try to fix it, they will charge me A LOT! If I am am wrong about the problem, can someone correct me? I made sure they were plugged in right. Thank you!

The set does not have a crt - its an lcd projrction
the most common is a hook up problem - you may have the reds backwords - varify the red audio and red video are not reversed
thanks

This sound like a picture tube that has gone out but may a circuitry problem and needs to be checked out by a profesional. Is the red tube lighting at all on any of the other inputs or menu?

Sony kf-50XBR800 tv turns itself on and off


I just purchased a replacement lamp off ebay and the TV is working fine now. Color looks better too (which I guess I should have expected). Search for "REPLACEMENT LAMP SONY XL-2100U" on eBay and look for seller "niosales". I paid $129 out the door. Their are other auctions for this lamp you can check out. Make sure you look at lamps that include the entire lamp housing, not just the bulb.

Grand Wega picture going on and off; standby light flashing, sound remains on


Is the cooling fan running properly?  I'm just guessing, but it sounds like it could be overheating and shutting off, which allows it to cool off enough to turn on and overheat all over again.

Sounds like a light engine issue to me. Is there anyway you can post a picture of the issue itself?
