IC Failure In Philips Radio DL167
MAKE AND MODEL: PHILIPS DL167 AM-FM RADIO
COMPLAINT REPORTED: Not picking up any stations.
HISTORY: This Radio had visited me once in March, 2018, though I could release an article only in January, 2019. Please see link : https://jestineyong.com/bad-capacitor-found-in-philips-radio-dl167-40/
TROUBLESHOOTING AND RECTIFICATION: I checked and ensured that the voltages to the IC CD2003GB were ok. The crystals were not oscillating in AM or FM when I checked and moreover the IC was getting warm soon after switch on. A clear indication of the IC failure. As I had a bad experience of trying to remove the SMD IC by a blower on a previous occasion (Please see https://jestineyong.com/bad-am-fm-ic-replaced-in-philips-radio/), I decided to use an IC Cutter Tool. Removed the IC and replaced with a new one.
As no other defects in any components were detected, applied power and found that the set worked very well. As before, I never charged anything to my dear old and most revered School Master, who is nearing his century! The gleam of joy that I could find on his and his wife’s eyes (another teacher) when I delivered the Radio to them, cannot be explained in any words and cannot be valued in terms of money! Mission accomplished and utmost satisfaction got added to its collection!

Thanks for mentioning the CD2003GP IC in this repair. I knew about the EXAR XR2003 often used in washing machines and dryers, just like the 2004 but this AM/FM IC is less known with interesting features and is still available. https://www.datasheet4u.com/datasheet-parts/CD2003GP-datasheet.php?id=653642

you may try with some chip quick low temp melt desoldering alloy... its under 20$ and will get the job done 110% far more safely and easier... have a look!

Sir,
some time this type of "Cutting" practice may worst the job if you are working on "Multi layer" PCB.Chances are more to damage the Traces underneath IC.(If the pressure for cutting is more).....you can use some Jigs made of simple Copper Wire if you are not comfortable with Hot air workstation.
Here are Some De-soldering Idea Without Hot air.
