No power

Did the set just turn off and stay off? Has the set been turning itself off and then back on before this issue. If you push the power button, does set set cycle on and of 3 times?

If it just went off and stayed off, the first thing I would check is the main fuse near where the power cord goes into the set. You'll have to take off the back and then unscrew and unclip the plastic cover in the back where the various inputs and out puts are. Looking down after removing the plastic cover you'll see a glass fuse that snaps onto the board. Check and replace that fuse if it's bad.

If the other symtoms I mentioned happen then it's most likely the HV splitter up in the front part of the set.

Tv won't turn on

Usually this problem is caused by part failure on circuit board. Most often in power supply or deflection circuit. You will need test equip. and soldering/desoldering tools to fix this set. Most repair services charge 275.00-475.00 to do this repair on a PS60690. Crate is removable by removing rear cover, disconnecting spk. plugs and keyboard plug. Loosen two screws and whole thing slides out. This can save you service call fee.

Proscan not turning on

Actually, the set has the PTK188AC chassis. This is a very uncommon chassis. The most common reason for the set not starting in that chassis is a shorted high voltage splitter. That is the large black box inside the set that has 5 thick red wires in it. When the set is turned on, the computer senses the short in the high voltage circuits and immediately shuts the set back off. When the set is on, that box has dangerously high voltage in it so it should only be replaced by a qualified tech familiar with the high voltage splitters in RCA projection sets.

Proscan 60 inch

You can get ahold of PTS Corp to get the board rebuilt, how do you know the transformer is bad? Sometimes the HV distribution block shorts out. Can you hear the HV "Squeak" 3 times when you press power, if so probably bad transformer. The whole board wont be available new, might be able to pick up a rebuilt one, will have to be careful with the HV leads.

60inch rear proscan picture hour glass problem

Most likly this set has two or maybe trhee problems .. first one sounds like a main power filter is open or the main power supply is at fault. the second coulkd be related or the cause of the first problem and could be shorted convergence ICs. the third could be a bad flyback transformer and good luck if thats the problem.. if the sets 10 years + in age, i would think very seriously into investing much to get this one going again.
