Are There Any Modification Kits For Philips TV 30PW8402/37?
The chassis is A02U AA. I've got two sets that failed within 12 months.
Both won't start up. The SSB's are OK. Any input is greatly appreciated. Philips no longer has a tech help line for non-authorized repair shops. Mark Affordable TV Repair |
