Expect slow response this is on old pc. I have a Panasonic

Greetings, Expect slow response this is on old pc. I have a Panasonic CRT Television Model CT2508 (yeah an antique) on which the verticle hold has gone out. When I turn the set on all I get is a bright horizontal line running across the center of the CRT. Adjusting the verticle hold controls on the back has no effect. The manual for this Panasonic Television Model CT2508 set is on my Box.com site at https://app.box.com/s/yy6zkg5x0adt0t2q1l9tl26vn6dmbfeb). On page 15 in the parts list it shows under VR controls: Ref No. Part No. Description ----------- ------------------------- --------------------------------------- R428 EVTV0U00MB52 Vert hold 400 Ohms Apparently a 400 ohm resistor. Do you think this is the part that needs replaced? If so, can you recommend a supplier? See spec particulars in the circuitry screen shots, (page 11 in the pdf), below. **********************

My TV repairman tells me that the newer large Flat screen TV's

My TV repairman tells me that the newer large Flat screen TV's are made in China and need repairs sooner and more frequently. Are some brands and models more reliable?He suggests (of course) that we repair the circuit board of our 2004 Sony Triniton XBR 34 inch Tube set because it does have a fantastic picture quality and will last for many more years.The only problem now is that the set does not always turn on. If we keep it turned on 24 hours a day we have not problem. But if we turn it off we might not be able to turn it on. Do we pay for the repair or do we buy a new larger flat screen TV?
