LINES or noise from left to right etc. This is a classic problem in a lot of these sets--that this clears up after a while is also typical---the period will gradually get longer and longer for it to become normal.

This set uses a Hyper board for all signal from all inputs---about two dozen tiny surface mounted filter capacitors on that board---they dry out and lose value---flat caps will when hot attempt to regain some of the value they should have.


Board is no longer available from Toshiba, only way to fix is remove one in set and send out for repair to someone like PTS Electronics.

I have seen experts try to replace the tiny caps--usually several are off value or open---cheaper to send board out. Last one I saw cost was about 200 for rebuild, keep in mind same problem will happen again in 5-8 years.


Let me know if you have questions and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

HCL652W picture faded will bulb replacement fix this


I would say that it is not worth replacing the bulbs. I had a similar experience with an old rear projection TV like that and I just cleaned all the dust out of it as well as I could. i cleaned the back of the screen, the mirror that the image reflects off of, and the bulbs themselves. I used a dry micro fiber cloth so as not to scratch anything. doing this might help you some, but if it is working and it is bright enough for you after a few minutes, I would just live with it until you can upgrade to a newer TV.

50 in sony rear projection tv screen has yellowish or greenish tint in center 1/3 of screen


OMG. If it is a rear projection LCD then you have a bad light engine. Any good repair shop will repair for $200-250.
If its an older 3 tube projection then you have contaminated coolant in one or 2 of the picture tubes. Just drain out the fluid and replace with new. Should be able to do in 15 minutes. total cost $45.

Lamp problem?


your picture processor is broken. we have the same tv, after 1 year problem started. we got a tv tech out and he looked at it and said it would cost $1800 to fix and this is after we bought a $400 bulb from sharp. this problem is in many of the same tv's of this exact model as we've invstigated and sharp is unwilling to help. there should be a classaction suit or recall for this exact tv.do not buy bulb , it will not work

Red screen


It sounds as though your Picture tubes are getting weak or theres a bad capacitor in the screen drive circuit. The only way to tell would be to call in a tech to diagnose this problem with his test equipment. A tv set is not a place for an unexperienced person to play with. Good Luck
