Question about Samsung HCM4215W 42" Rear Projection Television

Samsung 42" rear projection HD tv issue

Ok man , thanks for all your great responses. after doing what you said , there is still no reset factory convergence, and the guy i talked to at samsung said this is a DLP TV and not a CRT tv.. im confused because i thought the CRT PCB attached to the bottom of that HUGE CRT tube that i changed might indicate its a CRT TV and not a DLP TV LOL....
i guess ill try and install the new board tomorrow when it gets here and hope for the best , the convergence is SO close to right even with the IC board unplugged that im "hoping" that it auto resets the convergence to factory tolerance. im at a loss i feel like i have gotten a half year one of a kind TV when the manufacturer tells me its a DLP and it is Obviously not!
i guess what i really need to know is:
1) how often are these IC/main convergence boards shipped bad.
2) does the actual convergence board that attaches to the chassis with the one screw have to be connected securly? as in does it gain ground from the chassis in any way? if so i am going to use dielectric grease and a wire brush to make better contact to the chassis.
3) how long would it take to blow the IC's before i can get the convergence set and lastly..
4) should i even use perfect focus or actually set each cross hair for each color (only has red and blue that you can change) THEN use perfect focus.
Thanks for tolerating my n00bishness and helping me out man ,

    thank you

    As i speak the TV is on and working GREAT !!!! its got some convergence issues but thats cause i messed around with the yokes out of desperation after the original BOOM. no its a TV again!

    well i wanna thank you fixya.
    the error i get now though is no sensor data for perfect focus. i guess im happy that its not a 13" TV sitting ontop of the 80" entertainment center LOL
    its wierd though cause the perfect focus worked once before i hit the Mute,1,8,3. since doing mute,1,8,3 it dosent work , but i can still use Mute,1,8,3 to do it all over
    thanks again

1 they are either rebuilt or a defective returned to stock accidentaly
2 yes securly attaching it helps the heatsinks keep even cooler. no you don't need heatsink grease.
3 if the tolernace is very far out of wack then it woun't take long befor they blow. once you have instaled the new board turn on the set enter mute,1,8,3 then perfect focus on the remote let it do it's thing then shut off the tv and resart the tv and press perfect focus again.

Multipoint blue convergence cannot be adjusted

Sound like you need to replace the STK's and any blown pico's on convergence board.

I have a 42 Sony flat screen it has a blue blob in the lower left corner what do I do to correct this?

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Blue and red overlap shadowing

convergence ic's are your culprit. they are responsible for aligning the 3 colors your tv projects onto your screen..

Convergence problem ,Help Please

Something is not right here. Is there any possibility that you can get the circuit designation (Rxxx) of the resistors that were "incorrect"? I am not aware of anything like this that can cause the "memory to be erased". The only memory in that area would be the factory convergence settings which can be modified from the service menu. Please try to supply the resistor IDs and I'll check on this.
