HDMI Problem

[chriskaraokeman]

Hi folks , my PS3 will not play games via HDMI , after reading up , i found out about the HDMI clock problems it sometimes has. I rang Sony , who were not interested cos i bought it second hand I wouldnt mind, but its a 40 gig that were only launched last Oct.
Anyway , reformatted it , and tried it through composite input on my TV , and hey presto , everything works fine !
The thing i cant understand , i have got 2 HDMI cables , and they both give blocky or no graphics , but both used to work fine. Should i bite the bullet , and spend a load of money on a top HDMI cable , or is it cos i got a cheap unbranded HD tv , and need to get a decent TV ? Like i say , ive only had it for 3 weeks , and it worked fine at first Bluray movies play fine still though , via HDMI
