Philips Rear Projection Model 55PP8620 - convergence problem

Hello,

My 55PP8620 has just lost its colour convergence. I have tried to correct the colours both manually and with the inteligence system. A local TV technician says I may need to replace the convergence system. Are these still available in Australia or can I purchase elsewhere? I opened the back of the TV and found a 5cm square box mounted in the centre of the unit. This is marked 'Sony' and has the words 'screen' and 'focus' plus 6 small tuning knobs. The TV has had previous repairs - is the Sony part standard in this model Philips TV? Thank you for your support.

Manufactures sometimes contract with other tv companies to build their tv. Regardless of the internal hardware you still have a philips tv. I beleive this set was made by Hitachi. And what you are looking for is a replacement board. This board is referred to as the small signal module. When contacting a rebuilt board, have the model# and the chassis# available. And contact PTSELECTRONICS.com or Andrews Electronics.com. The board you seek is in the rear lefthand side on the floor of the TV. You will see a pair of tall aluminum fins. Theses are the heatsinks for the convergence ICs. I would definitely replace this small signal module, as repair on the local level will require pulling the board in and out of the tv several times. The company will give a part number and then you may order this. Striving for success the first time!!!!

I need a lamp replacement the original in Sonystyle cost me $299.00 a Philips lamp only without a cage $80.00 is it true that this lamp is the original for sony?


Hi,
Sony original lamp is longer lasting and supplied as per standard where as bulb only does not work like original lamp, many times it will be required to replace again after couple of months.
My opinion is to go for Sony original lamp that is no doubt bit high priced item but works great for years.
Hope these info will help you.
Thanks.

I believe you have convergence problem on your rear projector TV. It require to replace may be 2 IC output convergence or the convergence drive, after replace those component you need to readjust convergence which mean you move the RED GREEN BLUE to be 1 on top each other you must have the remote control and service manual to get into the service mode, if you thing you can get those part in your country the service manual I may help you with that, ask your husband if he like to challenge it. I hope that is give you some ideas
Cheers

This is a relay that has gone 'spastic' a protection device- something like a bi-metal thermostat on an iron or kettle. Now you know that what can you do about it? Its up you you to see in you can find it an fiddle I suspect that like kettles and irons these things are not made to be repaired. You could try Philips customer support of course.
