i checked them four things they read ok but i changed them anyway but still the same the cap gets hot and bubbles at top.i read on this site that if the power supply fet transistor had shorted then ic 101 would have gone could that be the case as if so i would scrap the tv,but would that cause this cap to go any advice appreciated as always

i eventually got this tv working but the sound is ok and the picture is there in a fashion its hard to discribe its like more grey and black there is some couler but its hazy like under water and with no signal the raster isnt normal more of a dull grey with white dashes across it much the same as the old phillips video used to be when the heads had gone in your experiance would you put that down to the tube any advice appreciated
