    Trying to change the glyol is dangerous and risky--blue will usually be bad but my guess now is a careful inspection is going to show glycol has leaked from the seals somewhere and got on the boards--careful as very toxic---look for the leak I suspect you will find--water will remove it but gloves should be used as it will get absorbed into your body if touch it. got glycol leak?

    a simple way on this brand is to unsolder all 18 pins on both chips completely and see if set comes on at all--the knock off thing is a myth. Upper right corner on the chips is a letter and number sequence---production code--seen Mitsubishi chips that wholesale for 22. 00 with same production run number as the generic that cost 7.00---like looking on ebay and seeing exact same auto part with a wide choice of prices.

    Sorry, I have a Phillips Magnavox 9P5534C103. The pic was bowed and shrinking. So to start with we thought while we were working on the TV we would go ahead and chang the Coolant Fluid because it was discolored. And clean the lens. That task went pretty good. Then all that worked good and Tv color was better but pic was still bowed and shrinking. On the convergence to line up color the green is very blured. So he changed the Convergence Ics. Then when we went to cut the TV back on and you could hear it try to come on but nothing nothing but the light on the front of the TV. And I cant find a service/repair manual. Anyone have any suggestions.

    He checked all of the resistors and they all seemed. We are going to check it out again this weekend. Checking the fuses and etc. It's been a busy week. And I think the ics i bought ended up being the knock offs i am reading about. How do we check to see if i got bad ics. We are looking for a service/repair manual for it? Thanks for all of the info we have got this far.

SOURCE: convergence no adjustment

There are black in color circuit protectors in the set that have blown because of the bad convergence IC's. You will need to measure the voltages on the ICs and make sure you have the correct plus and minus voltages. There should be about + and - 24 volts on each IC. I'm afraid the only way you will know what voltage are what and where they should be would be to get a service manual. i am sorry i do not have this model to share with you. Good Luck.

EVERYTHING IN WRITING IS DOUBLE AND THE PICTURE IS DISTORTED


Hello Tim this is a very common problem with the projection tv set, the problem is coming from the convergence board with faulty ICs that have to replaced in order for your tv set picture to work properly,they do sell convergence repair kits for your tv set but i would not recommend this the reason being is that if you make a mistake while changing out a component your whole tv set is gone not going to work anymore so for this i would recommend for you to call a near by tv repair shop and have a tech come out and change this ICs for you, after you change this ICs from the convergence board your tv set should go back to working normal on the link below you can check out how a convergence board looks like thank you hope this helps.

Are your colors out of convergence also? If so this is a classic symptom of bad Convergence ICs.
