Philips 50P8341 50 in. No picture,no sound and chirping noise. What could this be? Thanks.


Problem is on the middle (main/deflection) board. The chirping is a sign of shutdown, a short usually there. It can be a transistor or capacitor but someone with knowledge needs to get at the board and test things for a short.

Let me know if I can help--this is not a set for a novice to work on; rather difficult to into service position--do not attempt to remove center board--there is a better way.

In the shop I work for several techs refuse to work on these sets and I as a result have worked on a lot of them. I am a hired gun for them on certain sets.

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

Coolant is highly corrosive and will destroy any component that it touches. So the components will need to be desoldered and removed then tested and reinstalled. Also turning the screen adjustments too low will prevent the CRTs from turning on.

Chances are you will the small signal board. Donot confuse it with the small signal module. You will be replacing a board the size of a playing card. Part# PH3912725871. Follow the instructions that accompany this part. Mainly you will have to adjust the geomtry.

How would you replace the coolant for a philips 50p8341 50 in rear projection television


you have to remove the picture tube, drain the fluis through the drain plug, then take the lens cap off, clean out all the crud, then fill it up with new fluid, don't try to do it while it's still in the set, you could spill fluid on the board and cuse major damage, also, if you remove the tube, usually you will need to re-adjust the convergence of the tubes, usually only the blue and green tubes need this, pretty major repair, i don't recommencd doing it yourself, but getting a qualified repairman to do it.

Board repair


Hello sportylakey,

I would suggest first that you have a technician come over and troubleshoot your problem to determine which stage of the TV is malfunctioning. Then If you want you can have the technician repair the problem or swap out the board. This believe it or not is the cheaper option. I know that today a lot of people think that board swapping is the best thing, but in reality it's just a time consuming object lesson in futility, because you never know if you have fixed the problem or just bought more time. In any event try the option above, and if that is not to your liking try to send the boards to http://www.ptscorp.com/. Contact them to discuss your options on sending them the boards.

I hope this helps,

Thank you,

Sounds like the blue convergence IC s bad. They are relatively easy to replace if you can solder they cost around 10.00 each and you should change both the red and the blue.
