Rear projection TV's are very prone to failure, they are among the most asked for help. Unfortunately, there is a myriad, of "Causes" that portray, those symptoms.

Please find above, Field Training manual, this is what us engineers are trained on to repair these sets.
I get similar ones frequently at my shop. So if you find, you do not want to do the repair, please contact, a Sony head office, and ask for a referral to an authorised service center, then ask for a "Quote" before proceeding with any repair.

Do you know where to get an owners manual for a Free Spirit BMX bike from 85/86 bought at Sears? Who made that bike, Murray or Huffy? Does having the serial number help me?


well if it helps neither murray or huffy ever made free spirit this is a bike company thats been around for a dogs age making discount rate bikes the murray company folded about 15 years ago and huffy has been bought out so that their bikes can be built on a budget with a name once able to draw customers and sears has never really sold any bikes worth holding on to in my opinion and i ride an older bike made by intense cycles from california good luck and if it has plastic spoked wheels you shouldnt have a hard time selling it hope this helps:)

I have a Panasonic 32" tube television that is only 6 years old (Model CT-32D31) that we bought from Sears. We suddenly have nothing but a horizontal white line across the screen, which "grows" into a...


Sounds like 'bad' or 'dry' capacitors in the vertical deflection circuit. Please note that leaving the white line on the screen too long can burn in the screen, which is permanent damage.

Who makes proscan tv?


Proscan is produced by ON Corp. They are a leading producer for most LCD screens used by a large group of TV makers. Proscan used to be a high end RCA product. The CEO of On Corp was the head of the Proscan division of RCA. After Leaving RCA and Beginning On Corp he purchased the right to the Proscan trade mark. Thus a new beginning for a old name. Many people still belive it to be an RCA TV but it is not. It has good ratings in most reviews for TV's in it price range. It is now a sears brand much like Dynex is a Best But brand.

My braun plusonic wasable 549 class 2 will not hold a caharge i bought it 5 monthes ago 


You may have ended up getting an older model even though you bought it 5 months ago. The rechargeable batteries lose the ability to recharge after some time (usually a few years). You may still be under warranty with Braun, so check.

Panasonic pt-52lcx65 picture problem


Have a sears technician come over ,call them and set up an appointment, they are the best techs out there for tv issues, they will come out even if you did not buy the tv from them. Most of the Sears tv techs come from Philips which closed down their tech shop a while back. It sounds like you have dirty or faulty fans on your board. please advice.
