Do the 2 av cables available for psp in the market display games on a crt tv ?
By CRT TV I assume that you mean a standard-definition TV, as opposed to a high-definition TV. LCD and Plasma standard definition TVs exist, and a few high-definition CRT TVs were made as well. The way that the image is produced is irrelevant to the cabling. The answer depends on the PSP model that you have. The PSP-3001 and PSP-Go can display games, video, or other display content on any standard definition TV using either cable. The quality of the image will generally be better with the component cables, compared to the AV, cables; but either will work. The PSP-2001 can display photos, video content, and music visualization on a standard definition TV using the AV cables, but you cannot display video generated by a game using the AV cables at all. To display games on a TV with the PSP-2001, you must use the component cables, and in addition the TV must support the enhanced definition (480p) video mode. Only a small percentage of standard definition TVs support this mode, and a CRT TV almost certainly does not.
To sum up, in most cases a PSP-2001 will only be able to display photos and video content on a standard-definition CRT TV, no matter which cables you use. You will need component cables to have any chance of displaying video from a game, and even then you will need a progressive-scan TV. A PSP-3001, or PSP Go, will be able to display anything on any standard definition TV using either type of cable, but you may get a better quality image with the component cables. Also be aware that the PSP-2001 and PSP-3001 use the same AV and component AV cables, but the PSP Go uses different cables that are not compatible with other PSPs. The PSP-1001 can't display on a TV at all.
