My projector shows a blue tint to the right of the screen. I am afraid that it might be the blue LCD panel gone bad. What might the diagnosis be? Sony VPL-HS51


Does the blue tint show up as small rectangular pixel shapes when you get up close to the screen when focused properly. This would indicate a blue LCD panel fault. If it's fuzzy then possibly a blue polarizer overheating

Blue Haze on screen Sony cineza vpl-hs50 projector


Its your blue polarizer going bad. This happens over time due to the excessive heat generated in the projector. The main problem is that your projector has organic LCD panels that degrade over time and in turn degrades your blue polarizer. The same thing happened to my sanyo Z2. It took 5 years for it to show on my Sanyo because I only use the projector for sports and movies. not daily tv watching. In any case, it isnt worth it to spend the money ti fix it...jut put tat towrds a new projector. The latest crop of LCD projectors almost all use in-organic LCD panels that last much longer. Hope this helps.

Sony tv model no. KV - 19 APR 2


This is for a different model, but I had thin horizontal lines in red and had to adjust the tube for red. You may have a similar adjustment on your set.

I had the same problem with a Sony VPL CS1. It's not the mainboard, but the blue filter - cost to repair runs around $500 US.
Hope that helps.

It's hard to say, based on your description, if your symptom is caused by the power supply or vertical circuit. Do you mean there is one thick black area that moves slowly up the screen ? If so, do you still have picture and sound while this is going on ?

samsung pn64f8500 boot loop with evoulution kit 3000za installed I had perfectly working Samsung plasma ph64f8500 working fine with Samsung evolution kit 3000 ZA installed. Then we moved I took off the evolution kits so the movers would not knock them off. I powered up without the evolution kit installed accidently. Now both plasma are stuck in boot loop. They power up but go to the smart tv logo and cannot find the evolution kit. I read somewhere a long time ago that I needed to reset the evolution kit to a state where it had not been installed. The current issue is the Main Logic Board eeprom instructs the unit to boot correctly but it cannot find the evolution kit. If you boot without the evolution kit the system halts and indicates on the screen the evolution kit has been uninstalled and you must install it if you wish to view. If it could find the evolution kit one could go thru the menu to uninstall it correctly. One option is to manually reset the eeprom to remove the install instruction that boots looking for the evolution kit. I have been looking for the eeprom on the Samsung main logic board but I cannot download the logic board schematic. I cannot find the logic board number. The main logic board is BN94-0625C. The logic board has tow other part number references.• MFR Part Number 1: Samsung BN94-06205C • Board Number(s): BN41-01998A, BN97-06633G i have been researching the logic board IC Numbers and belive that IC 1701 is the eeprom that requires reset. The youtube videos for similar models indicate a eeprom that is listed as a part nmber for this samsung pn64f8500 unit as 24C512 and shows how to jumber 2 IC locations that will force the eeprom to reset to standard starup without the Evoution Kit 3000
